Alpine Electronics SWE-815 300W 8" Active Subwoofer, With Custom Enclosure, Remote Control, 4Ω Single Voice Coil

The media could not be loaded. One of the best compact sub-woofers on the market for a reasonable price! Wow, where do I start. I was looking for a sub that would not take too much space in the boot since I got a small hatch ( Mazda 2). You will see how it fits in the boot on pictures attached. It is worth mentioning that boot space is very limited on Mazda 2 in particular. At some point I was even considering getting one of those under seat subs like Kenwood KSE SW11 and Pioneer TS-WX130DA. After numerous hours of research I found Alpine SWE 815. It comes with all wiring harnesses and instructions. Nothing additional is required in terms of wires, clips etc. All included. Alpine was cheaper at the time of purchasing (£99) in comparison to under seat Kenwood SW11 (£120) and Pioneer WX130DA (£130). So if you are on a budget go for Alpine. It took me many hours to install though. However, cable management took most of that time. Bare in mind. Actual installation time is not that long. Also, Alpine SWE 815 comes with a wired remote which allows you to select different frequencies and adjust bass according to your taste. Quite useful actually. However, still have to figure out some settings. Overall, I can say that this sub is a great value for money. Performance wise it is loud enough to make my car shake. It looks really nice, feels really good and sounds amazing. Will update this review in about 6 months or year to see if there are any faults or downsides.

I recently purchased this in-Car Subwoofer and I am impressed with its powerful sound and overall quality. However, I must say that the installation process was a bit tricky, despite the fact that the product did come with everything that was needed.The subwoofer produces deep, resonant bass that adds an incredible dimension to any music played in the car. It is well-constructed with sturdy materials, which ensures that it can withstand the vibrations and bumps associated with driving.However, I did encounter some difficulties during the installation process. Although the product included all the necessary components and wiring, it took some effort and time to correctly connect everything. This may not be an issue for experienced car audio enthusiasts, but it could pose a challenge for those with less experience.That being said, I was ultimately able to install the subwoofer correctly and the resulting sound was worth the effort. The powerful bass adds a new level of depth and richness to my music listening experience in the car.

First of all, it comes with the needed cables, fused battery wire, ignition cable, connection to rear speakers etc. Don’t make same mistake as I did and buy them separately and ended up returning.Second: sound is really good for it’s tiny size. I had a subwoofer twice the size before in another car, this one just blows my mind. Very punchy, very clear, very loud when needed!Installation is as with any amplifier, pretty easy. Instructuions provided are clear, but I have also watched a ton of youtube videos to ensure I don’t set the car on fire (first such install). For me it was more complicated since I stripped whole car to add sound deadening.Just to bring it live for testing purposes: 30 min? To actually tidy all the cables nicely maybe around 3-4 hours for someone who’s never done this before - me.I did have to buy some RCA cables because my 3rd party stereo has subwoofer output so might as well use it. Installed in an Astra H.So if you’re looking to add some base to your car on a budget, you don’t need to look further. Having a remote is also a very nice plus!

You’re probably looking to see how loud this is, I had fair few subs back in the max power days so I know what’s expected. I’d say if you have a standard factory sound system in a small or older car then this will be an upgrade, not shake the whole car to pieces loud, but it’ll more than add the bass that’s missing and you’ll be happy for the money you spent. If you have a newer or large car with a premium factory system like Lexus, Volvo, BMW then this won’t add much, you’ll notice it but it’s not adding anything to what’s already there. I fitted this in my older RX8 with a Bose system which had ok but not great bass to begin with and this is a perfect upgrade, I want to keep the car light and doesn’t take much space. I wasn’t sure if it would do for my newer Lexus with a Mark Levinson sound system and after fitting in the RX8 it don’t think it wouldn’t have added much at alI to the Lexus, I would need a single or twin 10/12 with 800+ watts to have that rattle the whole car amount of bass. Overall it’s a great small sub and the controller is nice to have when the partner has a headache. If you have a lack of bass to begin with or a small car this is perfect.

I’ve got a Toyota Aygo and the speakers in it just aren’t capable of producing any real bass frequencies. There was just silence where there was supposed to be low bass lol. I’d never imagined being able to fit a sub in such a small boot, at least not one that would be any good and was even looking at getting a new car because of the rubbish sound from the standard speakers. Then I came across this and after reading the reviews I bought it and installed it. Wow it completely transformed the sound in the Aygo. I now have bass and loads of it. I can now hear my music how it is supposed to be. I had already upgraded the head unit and used the RCA sub output and once I dialled in the crossover settings it sounds incredible. I just can’t believe how this tiny thing puts out so much low end (especially when vented) it comes with all the cables you need to install except the RCA leads if you have a sub out on the back of your head unit.
