bought 2

This amp is awesome. Bought 1 for my son for Christmas and hooked up to 2 kenwood 12s. It slams. The other I put in my 07 nissan 350z roadster. It's pushing 2 rockford fosgate punch 8s two rockford fosgate 6 1/2 & 2 rockford fosgate tweeters and 6 1/2 mids. It is awesome.

great product

I purchased this amp for four JL audio 6×9s and it really shines.I used the high pass filter at 80 hz and let the sub fill in the rest. Every connection is solid, high and low pass filter and a fan in case she over heats . great amp for the money.

good deal

This little amp surprised me. I hooked it up to 4 6x8 infinity's with a Kenwood deck in my moms car and it sounds awesome. I would definitely purchase this amp again in the future. I've installed many systems in the past and this is one of the clearest and loudest!!!

Nice Amp

This "Amp" sounds very clean, even on a high volume, I paired it with a Kenwood Head Unit and 6 by 8 Infinity Cappas on all four Doors and it sounds very good. Also, the price is very low and the shipping was free and fast, so I do recommend this Amp.

Great Amp!

I have this amp powering Polk DB651's and Db461's crossed over at 80Hz for the Db 651's and 150HZ for the DB461's. I also am running a Polk DB840 sub and Polk DB1001 Tweeters all running from Kenwood amps. The sound is incredible.

Great for what I didn't get it for

This amp is a really good quality amp. I was just a nube and paired it with subs instead of car speakers. It works fine until big hits because it's not really meant for subs. If my head unit wasn't powerful enough I would definitely use this amp for my speakers I bought.
