H YANKASODA-10ASW 480W 10 Inch Compact Underseat Car Subwoofer with Built-in Amp, Slim Powered Subwoofer for Car/Truck/Jeep Audio

As a single dad of three kids, I had an Audi A4 with a premium sound system. My kids and myself loved that car, mostly because of the killer sound system with subwoofer. Then I got married and her two kids, her Honda Civic, with my three kids, and my Audi meant we needed a van. I submitted my love away from my Audi and to my wife and our five kids, and traded the Audi for a new van. I was now the proud owner of a Honda Civic with the worst sound system on planet earth. The speakers were literally made of paper. And this was to be the vehicle I spend 1.5 hours a day in commuting to work. I was allowed to spend some money on upgrading the sound, but not a lot.My quest began in the search of the highest quality speakers and woofer my meager budget would afford. I got some Kicker speakers and tweeters and I found this under seat subwoofer for a great price. Due to budget restraints I had to keep the OEM head unit, so I purchase a LOC2SL line output converter to tie the subwoofer to the two rear speakers.The hardest part was locating a reliable power source for the LOC2SL in the web of unnamed wires within the Honda Civic. I gave up the search after failed attempts and settled on just using a fuse tap and tapping into the fuel injector pump fuse slot near the steering wheel underside for the LOC2SL power. This worked out great since this slot is only powered when the car is turned on. I just had to run a other power line from the front to the rear of the car, which was a bit of a pain.Long story short, I achieved reaching a sound quality very comparable to my Audi A4 with premium sound and subwoofer. This woofer really bumps and shakes the butt and bones. Having it under my seat took a little getting used to. I've always had a woofer in the trunk before and having it under my seat really gives a body massaging experience. This woofer does fit perfectly under my driver's side short Honda Civic seat. It won't shake the neighborhood or anything, but it doesn't lack enjoyment power. It's more than enough for enjoyment inside the car rather than making a public announcement of how annoying you can be to neighbors. Having the bass turned up full is actually too much in my little Civic. I enjoy bass heavy electronic music, and this definitely satisfies my bass heavy requirements to enjoy music on my long daily commutes. My children are bass junkies too, and they approve. I achieved Audi A4 premium sound quality by adding this subwoofer. After months of daily bass hitting usage in my car, in 110+ deg Arizona heat, I approve of this subwoofer.

I love these little speakers lol. I have the 8 under my driver seat(because the 10 won't fit with the electric seat) (2015 WRX), and the 10 under the passenger seat. Ran one single 4awg wire through the firewall and under my center console molding. Split off to both seats and works amazing!! Perfect amount of bass to fill in what my Infinity 603rs's couldn't.

Got this installed under the driver's seat in my '04 Tundra. Easy install, whole thing took me about two hours. I used the 8ga Boss wiring kit. Everything works as it should. I didn't want huge bass that rattles my whole truck, I just wanted something to take the strain of those lower frequencies off of the stock door speakers, and this does a great job of that. Get that low pass filter set right, was around 85-90Hz for me, and it will definitely breath new life into your stock audio system. Kick drums no longer rattle my door panels. Build quality seems good, but the lugs they use for the power, trigger, and ground terminals are cheap. When I was securing the ground wire, the head cracked in half with moderate force. It is tight and secure now, but I'm going to have a problem if I ever need to remove it. Only reason I gave 4 stars instead of 5. Still definitely worth the $87 I paid.

Can’t believe the great sound from this subI was replacing an infinity 10” powered subThat I spent $280 onThis cheap knock off speaker is heavier, built better and sounds better than infinitySmhYou won’t believe it until you hear it

I received it and had to wait three weeks to have it professionally installed. It sounded great. I loved it then one day I got in my Roxor and the radio came on and the Sub-Woofer didn’t.I checked all the fuses. Took it back to the installers they checked it out and said everything is hooked up correctly all the fuses are good. It ran great for two weeks so the installation is correct the next thing would be to look in it. that would have cost me more than the unit cost! It only worked for two weeks, and I only used it not more than a total of three hours in that two-week period, “Hell” I’m over 78 years old, it's not like I was rocking out 24/7, that’s some pretty expensive music wouldn’t you say? That’s what you get when you buy made in China!!!
