It's really nice bass proccessor I like it because I like to listening to Mexican music that doesn't have bass and it would put bass in it. And if I put English music it would sound double the bass.

I had never used one of this. But won't get another system installed without this thing again. Gives the best bass push ever alsome. Just try one. Words can't explain. N ull see for ur self1!!!!!!

I would and wouldn't recommend because everytime you turn it on it makes a noise

I purchased this product because I listen to alot of old skool type music and thought it would be a good addition to my system and it was I havent ever heard anyother product like this one so I cant compare it but it sounds good to me. Plus great service from sonic

Running 2 Kicker L7s on JL Audio G-Max 1200 and Pioneer 4300 head unit, RCA by Monster Cable, fiberglass doors with 10 JL Audio 6.5" speakers. It makes bass muddy when you turn it up on the unit. Sold unit for 25 dollars. I'd rather get something for nothing.

Cost effective and way more impressive than I thought it would be. I bought this with my fingers crossed and had great luck with the purchase. The filters work beautifully. I would definitely recommend this product. Especially over more pricey options. The only issue (and this may only be with mine) is that the gain buttons can be a little sensitive, but it's such a minor inconvenience, it's hardly worth the mention.

Works great! Gives extra bass.

I really like this unit. It seems well built and does make a big difference. I only have one issue... why anybody would want blue lights blinking every time the bass notes hit is beyond me. That's just plain stupid.

I bought one of these a couple of days ago. The lights didn't work at first. The second problem was that all of a sudden it stopped working. It doesn't turn on at all.

I like it for digital bass processor it add more bottom to your bass drop and you can really feel it. I have it running with two 1200 watt brutus driving 4 alpine R 10's and it sounds like 6 12's i'm hitting at 186dB's in a 95 infiniti you can't sit in there and crank it to 10.

This will add bass to any song and give that deep bass sound to songs that have less than satisfactory bass frequencies buy this way batter than audio control epicenter its less expensive but all the same in function has my to tens hittin deep lows
