Works great on the boat
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Very powerful and compact. Sound quality is excellent. Small form factor makes it easy to install on my boat and is exactly what I was looking for. Ability to run a set of speakers and bridge the other 2 channels to run a subwoofer reduces the power required, which is critical in a marine environment.

Awesome amp for small spaces
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I bought this amp, some upgraded Polk speakers for the dash and a 6" Bazooka sub for my stepfather this last Christmas for his 1994 Toyota pick up. Best Buy did the install and did a great job. 45 watts per speaker for the dash and 90 watts to the sub and it sounds pretty thunderous in such a small cab. Amp installed right behind head unit with no issues. My stepfather thinks he is in the front row for a Bob Seger, so I am very happy with my purchase!

Music sounds clearer
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.The alpine power pack is feeding off the original headunit in my 2013 Nissan Altima. The sound of the music coming through my newly installed jbl gx602 and jbl gx 963 sounds is loud enough and clear.

Our son's review
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.My son did all the reviews and tends to like the "best of the best" and went with this. He installed it himself. The best part of the entire deal was the customer service we received from the sales person. He knew his stuff and confirmed everything my son had researched.

Perfect for my application
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Great little amplifier. Easy installation. Just perfect to run a set of 4x6 kickers. And at some point either a sound bar or another set of 6x9 kickers.

Great amp if you don't want to spend a lot.
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.This amp is great. I have 4 Infinity 6x8 speakers in my F250 and they just didn't sound to much better than stock. I was going to replace them with some Kickers and was told about this amp. It takes up no space and is mounted behind the dash. It sounds amazing!!!
