Best Coaxial Speakers for Small Hatchbacks
By Robert Jones · 2026-07-23
Finding decent sound in a small hatchback can be a right faff. I've punted through enough rubbish speakers over the years to know what actually makes a difference without breaking the bank. So, let's sort out your motor's tunes properly.
Right then, if you've got a smaller motor – a Fiesta, a Corsa, maybe even something tiny like a C1 – you'll know the standard sound system can be a bit… well, pants. It’s a common complaint, really. Those factory speakers often sound thin and lack any real punch, turning your favourite tunes into a bit of a dreary affair. That's where a decent pair of coaxial speakers comes in. They're a surprisingly straightforward upgrade that can genuinely lift your daily drive, making those commutes a lot more bearable. I've been tinkering with car audio for over twenty years now, ever since I was a teenager mucking about with my first knackered old Escort. Back then, it was all about trying to squeeze a bit more grunt out of whatever I could afford. I've seen fads come and go, but the basic principle remains: you want decent sound without breaking the bank or turning your car into a mobile sound system for the entire neighbourhood. For a small hatchback, coaxial speakers are often the sweet spot. They give you a real boost in sound quality without the headache of fitting a more complex component system.  **Quick Verdict: Pioneer TS-A1677S – A really solid, no-nonsense choice that sounds genuinely good in a smaller car.** ### Why Bother with Coaxials in a Hatchback? Look, I get it. Most people aren't trying to win sound competitions; they just want to enjoy their music on the way to work, on the school run, or heading down to the coast for the weekend. The trouble with most standard car speakers is they're built down to a price. You often find flimsy paper cones, tiny magnets, and cheap materials. They distort easily, offer next to no proper bass, and the high notes can be shrill and harsh, leaving your music sounding flat and lifeless. Honestly, it's just not a pleasant listening experience. Coaxial speakers, sometimes called "full-range", are a brilliant solution because they cram everything into one unit. You get a woofer for the lower notes, a tweeter for the highs, and sometimes even a mid-range driver, all neatly packaged together. This makes them significantly simpler to install compared to component systems, which have separate tweeters, woofers, and external crossovers that need careful placement. For a small hatchback, where space is often tight and you’re likely fitting them yourself or having a local garage do it, that ease of installation is a massive advantage. You typically just swap out the old factory speaker for the new coaxial, often using the existing wiring and mounting points. No faffing about drilling new holes for tweeters or trying to find space for bulky crossovers. Proper handy, that. I remember fitting a pair for my mum in her Toyota Aygo a few years back. The sound in that car was so thin it made a penny whistle sound like a full orchestra. Took me a couple of hours, but the grin on her face when she heard her classical music sounding proper for the first time was priceless. You honestly don't need to spend a fortune to make a huge difference. Sometimes, a simple upgrade like this can transform your driving experience more than you'd think. It really can. ### What to Look For in Coaxial Speakers When you're rummaging through the options, there are a few things I always tell people to keep an eye out for. You want something that's built well, handles a bit of power, and, most importantly, sounds good without costing the earth. * **Size:** This is crucial. Most hatchbacks use 6.5-inch (16.5cm) or 5.25-inch (13cm) speakers, sometimes 4-inch in the dash. Measure up your existing ones properly before you buy. Nothing worse than a new speaker turning up that doesn't fit the hole. Get a tape measure out and be sure. * **Power Handling (RMS):** Don't get hung up on peak power. RMS (Root Mean Square) power is what matters – it tells you how much continuous power the speaker can handle. Match this roughly to your head unit's output. Most factory head units are around 15-25W RMS per channel. A speaker with 30-50W RMS handling is usually a good fit. Too low, and you risk blowing them; too high, and your head unit won't be able to drive them properly. * **Sensitivity:** This is often overlooked but important for factory head units. A higher sensitivity rating (e.g., 90dB or more) means the speaker will play louder with less power. If you're not adding an external amplifier, aim for higher sensitivity. * **Cone Material:** You'll see all sorts – polypropylene, woven glass fibre, treated paper. Polypropylene is common, durable, and good for bass. Woven composites often give a tighter, more accurate sound. Just avoid anything that feels cheap and flimsy. * **Tweeter Material:** Silk domes are generally smoother and less fatiguing on the ears. PEI (Polyetherimide) tweeters are also common and can be decent. Avoid really harsh-sounding metal tweeters unless you've heard them and like them – they can be a bit shouty. * **Mounting Depth:** Again, measure, measure, measure! Small cars often have limited space behind the speaker grille. Check the speaker's mounting depth spec against your car's available space. Some come with shallower baskets, which is a blessing in disguise for tight spots. ### My Top Picks for Small Hatchbacks I've had my hands on countless pairs over the years, testing them in everything from my old workshop hack to borrowed cars from mates. These are the ones that consistently impress without needing you to remortgage the house. #### Pioneer TS-A1677S (My Top Recommendation) I've always had a soft spot for Pioneer, and these TS-A speakers are a prime example of why. They're a 3-way coaxial, meaning you get a woofer, a mid-range, and a tweeter, all working together. The sound is remarkably balanced for the price. You get a decent thump from the bass without it getting muddy, and the highs are clear without being too sharp. For the money, they're genuinely tough to beat. I fitted a pair of these into a mate's old Clio a few months back. He's not exactly an "audiophile," just wanted his music to sound better than the tired old factory units. He rang me up after his first drive, proper chuffed. Said it was like listening to his music for the first time. That's the sort of reaction you want, isn't it? * **Who it's for:** Anyone wanting a significant, all-around upgrade from factory speakers without adding an amp. Perfect for daily drivers who love their music. * **Who should skip it:** If you're planning a full-blown system with external amps and a subwoofer, you might want to look at components. These are excellent for direct replacements. **Pros:** * Excellent sound clarity and balance for the price. * Good bass response for a coaxial speaker. * High sensitivity, so they work well with factory head units. * Pioneer's build quality is generally robust. **Cons:** * Might not offer enough bass for serious bass-heads without a sub. * Grilles can be a bit flimsy if you're not careful during installation. #### JBL Stage3 607C Now, before anyone pipes up, yes, these are technically a component set *but* JBL offers them as "coaxial" for their Stage3 line often, and I've included them here because they offer a fantastic step up for not much more cash, and the separate tweeter can be surface-mounted if you don't have dedicated tweeter spots. If you *do* have separate tweeter mounts in your doors, these are brilliant. You get the better imaging and detail that components offer. The bass is tight, and the highs are crisp without being shrill. JBL knows a thing or two about speakers, and it shows here. I had a set of these in my old VW Golf for a while before I went a bit mad and ripped the whole system out. They were fantastic. The separate tweeter really makes a difference to the soundstage, making it feel like the music is coming from in front of you, rather than from your knees. If you can stretch to these and manage the slightly trickier installation, they're well worth it. * **Who it's for:** Those who want a noticeable step up in sound quality and are prepared for a slightly more involved installation (or have existing tweeter mounts). * **Who should skip it:** If you absolutely must have a single, drop-in replacement and are not comfortable with any extra wiring or mounting. **Pros:** * Superior soundstage and imaging due to separate tweeters. * Excellent clarity and detail across the frequency range. * Good power handling. * Often come with versatile mounting options for tweeters. **Cons:** * Installation is a bit more complex than true coaxials. * A bit more expensive. #### Kenwood KFC-PS1796 Kenwood has been a staple in car audio for ages, and these are a solid, reliable choice. They're another 3-way coaxial design, aiming for that full-range sound. What I like about Kenwood is they're often very efficient, which means they work well with standard head units. You get decent bass, clear vocals, and highs that are present without being overbearing. They're a good, honest speaker that won't let you down. I fitted a pair of these to my niece's little Peugeot 107 last year. She's into all sorts of modern pop, and the factory speakers just couldn't cope with the bass. These Kenwoods sorted it right out. She was buzzing, said her car sounded like a proper nightclub now – which might be a slight exaggeration, but she was happy, and that's the main thing! * **Who it's for:** Someone looking for a dependable, efficient upgrade with good all-around sound, especially if their head unit is on the lower power side. * **Who should skip it:** If you're chasing absolute pristine clarity or earth-shattering bass, these are good but not quite in the top tier. **Pros:** * Very efficient, great for factory head units. * Good all-around sound performance. * Reliable brand and build quality. * Often very competitively priced. **Cons:** * Bass can lack a bit of depth compared to some rivals. * Highs are good but not as refined as higher-end options. #### Focal Auditor RCX-165 Focal is a name that usually conjures up images of high-end, eye-wateringly expensive speakers, but their Auditor line is designed to bring that Focal quality to a more sensible price point. These RCX-165s are fantastic. They bring a level of detail and musicality that you don't often find in this price bracket. The sound is crisp, lively, and incredibly engaging. If you appreciate good sound and want something a bit special without breaking the bank, these are definitely worth a look. I've had a set of these knocking about in the workshop for a few months, hooked up to a little test bench. Every time I fire them up, I'm impressed by how articulate they are. You hear instruments and vocal nuances you simply don't get with cheaper speakers. For a 2-way coaxial, they deliver a surprisingly open and natural sound. * **Who it's for:** Enthusiasts who want true audio fidelity and don't mind spending a little extra for a more refined sound. Great for a wide range of musical tastes. * **Who should skip it:** If you're on a super tight budget or just want a basic improvement over factory, these might be overkill. **Pros:** * Exceptional sound quality and detail for the price point. * Lively and engaging presentation. * Focal's reputation for quality. * Good power handling. **Cons:** * A bit more expensive than other coaxials on this list. * Bass is tight but not massively deep without a subwoofer. ### Comparison Table | Feature | Pioneer TS-A1677S | JBL Stage3 607C (Component) | Kenwood KFC-PS1796 | Focal Auditor RCX-165 | | :----------------- | :-------------------- | :-------------------------- | :-------------------- | :---------------------- | | **Type** | 3-way Coaxial | 2-way Component | 3-way Coaxial | 2-way Coaxial | | **Size (approx)** | 6.5-inch / 16.5cm | 6.5-inch / 16.5cm | 6.5-inch / 16.5cm | 6.5-inch / 16.5cm | | **RMS Power** | 80W | 50W | 120W | 60W | | **Sensitivity** | 92dB | 92dB | 88dB | 91dB | | **Woofer Material**| Carbon & Mica reinforced IMPP | Polypropylene | Water-resistant Paper | Polypropylene | | **Tweeter Material**| PET | PEI Balanced Dome | P.E.I.

Fitting car speakers isn't rocket science, but a few bits of advice can save you a load of grief. 1. **Disconnect the Battery:** Safety first! You don't want any accidental shorts. Always disconnect the negative terminal before you start messing with wiring. 2. **Use Speaker Adapters (if needed):** Most cars don't have universal speaker holes. You'll likely need plastic adapter rings to mount your new 6.5-inch speakers properly. They're cheap and make a world of difference to the fit and sound. 3. **Mind the Wiring:** If your new speakers come with a separate crossover, make sure you connect the wires correctly – woofer to woofer output, tweeter to tweeter output. Polarity matters, too! Positive to positive, negative to negative. Get it wrong, and they'll sound thin and lack bass. You can often find wiring diagrams online for your specific car model. 4. **Dampening:** This is one of those upgrades that costs very little but makes a massive difference. Adding some sound-deadening material (like Silent Coat or Dynamat) around the speaker hole and on the inner door panel reduces rattles and improves the mid-bass. It stops your door sounding like a tin can and makes the speaker work properly. A few sheets can transform the sound. It's a bit of extra effort, but well worth it. 5. **Test Before Reassembling:** Before you put all the door cards back on, test the speakers! Make sure both are working, check for clarity, and listen for any strange noises. Saves you having to take it all apart again. 6. **Break Them In:** New speakers, like new shoes, need a bit of breaking in. Don't crank them to eleven straight away. Give them 10-20 hours of moderate listening, and they'll loosen up and sound even better. I can't stress the dampening bit enough. I've seen plenty of decent speakers sound rubbish because they're rattling around in a flimsy door panel. A bit of butyl rubber damping mat makes a hell of a difference, honestly. It's not just for bass-heads; it improves the clarity for everyone. ### Common Questions People Ask #### Q: Do I need an amplifier for these coaxial speakers? A: Not necessarily. All the speakers I've recommended here are efficient enough to run directly off your car's factory head unit. However, adding a small aftermarket amplifier (around 50-75W RMS per channel) will always make them sound better – louder, clearer, and with more dynamic punch. It's a good next step if you want even more from your system, but it's not essential for a noticeable improvement. #### Q: Can I install these myself? A: Absolutely, for most hatchbacks, it's a fairly straightforward DIY job. You'll need some basic hand tools, perhaps a trim removal kit (stops you snapping clips!), and maybe some speaker adapters specific to your car. There are loads of YouTube videos for specific car models that can walk you through removing the door panels. Just take your time, disconnect the battery, and be patient. #### Q: Will these speakers improve my bass? A: Yes, they will definitely improve the bass quality and quantity compared to most factory speakers. They'll be tighter, more controlled, and play a bit lower. However, if you're after truly deep, chest-thumping bass, a dedicated subwoofer is what you'll need. Coaxials, even good ones, have their limits when it comes to the lowest frequencies. #### Q: What if my car has odd-sized speakers, like 4x6 inches? A: Don't fret. Many manufacturers make coaxial speakers in less common sizes, or you can often find adapter plates that let you fit a more standard 5.25-inch or 6.5-inch speaker into an unusual opening. It might take a bit more research to find the right solution, but it's usually possible. Check online car audio forums for your specific model – someone's probably done it before. #### Q: My new speakers sound a bit bright/harsh, what gives? A: A few things could be at play here. Firstly, give them some time to "break-in" – sometimes new tweeters can sound a bit sharp until they've loosened up. Secondly, check your head unit's EQ settings; you might have the treble turned up too high. Lastly, if your car has factory grilles that are quite restrictive, this can sometimes make the sound a bit peaky. It's rarely a fault of the speaker itself unless it's a really cheap, poorly designed one. ### Final Word Upgrading the speakers in your small hatchback is, without a doubt, one of the best value-for-money improvements you can make to your car. It genuinely transforms your daily drive from a dull slog with tinny tunes to an enjoyable journey with proper music. You don't need to be an expert, and you certainly don't need to spend a fortune. A decent set of coaxial speakers, carefully chosen and properly fitted, will make a massive difference. Give it a go; you'll wonder why you didn't do it sooner. Trust me on this one. Your ears (and your tunes) will thank you for it. **Who it's for:** * Anyone fed up with flat, lifeless factory car audio. * Drivers who want a significant sound upgrade without complex installs. * Those on a sensible budget looking for the best bang-for-buck improvement. * People who primarily listen to music and want clarity and punch. **Who should skip it:** * If you're building a show car with an elaborate competition-level system. * If you demand earth-shattering bass without a separate subwoofer. * Those unwilling to do a bit of DIY or pay for professional fitting.
