BOSS Audio Systems BASS8 8 Inch Under Seat Powered Car Subwoofer – 800 High Output, Low Profile, Built in Amplifier, for Truck, Boxes and Enclosures, Remote Subwoofer Control

No es tan potente, es para un carro prqueño y que el sonido vaya bien con ese pequeño bajo

No funciona como yo lo esperaba

Good option to add to a budget or stock car audio setup. Won't impress anyone but it fills in that missing thump and low end. Do note that this doesn't come with any of the required wiring, so make sure to pick up a wiring kit (I got some cheapo kit here on amazon for like $12, just make sure its at least 10 gauge) and I wired directly into the rear speaker wire. Out of the box it's set to a base non-tuned setting so won't sound good at all - you NEED to tune and adjust the settings on both the sub and your head unit. Read the manual, it explains how to set the gain. I think I ended up somewhere with the gain set to 3/4, bass boost almost near max, and the high pass filter a half or turn up from middle (this is important if you're regular speakers don't produce a lot of bass). I also turned down my head units "bass boost" setting from +3 to +1 as the regular speakers don't need to try and fill in bass anymore and let them shine more in their minds and highs.

I'm posting this as a one star review, so that people may not have the same experience I had. I hooked this up as instructed, in a 94 Geo Tracker with aftermarket Kenwood "media player" stereo and I could not tell it was working at all, very little thump. I jumped on the reviews and filtered to one star, and yup, many of the 1 star reviews were exactly the same as my problem, 6 X 9's in rear, no bass at all, can barely hear it over the 6x9's, etc. I was expecting WAY more out of it, as there were plenty of good reviews. Is it my cables? NO. hmm, I started adjusting the gain and other setting on the amp, (requires flat head screwdriver) and voila, I'm in business. Bass is definitely audible, and yes you can feel it, its not going to be earth shattering but it's definitely a huge difference and frankly quite good for the $.. in reality 5 stars, just check your settings and adjust, out of the box its not going to boom, but with some tinkering, YOU SHOULD DEFINITELY FEEL THIS THING.

The ONLY good things about this sub are (a) it did function once installed, and (b) I bought it on sale. Had I paid full price for this, I would have given it 1-star and immediately sent it back. As it is, I'm keeping it (reluctantly) just because it does help a little in my F150. But the simple truth is: Do NOT purchase this sub for anything except a compact car where the sub is directly beneath the drivers seat. Even then, good luck. This is just NOT a strong speaker in any sense of the word. Better than nothing? Sure. But a waste of money for "real bass" in a vehicle with more than 2 seats.
