Nice amp
There are no cons to this amp. The pros: Easy installation, has enough power for what I need it for and it looks great. I would recommend this product if you have a small car as you don't need a 1000 watt amp unless your in a band or running a pa system.

Decent Basic Amp
I'm powering (2) 6x9's and (2) 5 1/4 inch speakers with this amp. It does the job pretty darn good. This thing runs hotter than a firecracker tho so I think I'm going to put a couple computer fans on a relay to keep it cool. I was kind of disappointed seeing it only has a 15 amp fuse in it. However if it lasts 6-8 months i can't complain for the price.

Great little amp.
I have a 2003 Bonneville SLE. The stock system in it was lack luster. However, I put Polk Audio speakers in the front doors and pioneer 6X9's in the rear deck and it helped, but the punch and clarity at high volume just wasn't there. I decided to amp my system. This amp is great. It is easy to use, was rather easy to install (did it myself), and it's been over 6 months now and it has never skipped a beat. I like to blast my music, and even in the summer months it has never ran hot. The 6X9's bass is much better and the highs are clearer too. The 6.5 inch door speakers really pound now and they rarely distort. I would recommend it. :)

Works great
Already had 4 speakers with sub in expedition... wanted to add extra speakers to 3rd row and tweeter on dash... works great and kids love the improved sound for watching DVDs... I've had it now for several months... no issues

Alright Product
When I first installed this amp I had a dead channel from the start, but the other three channels that worked sounded great and was a definite improvement over the stock sound.

Gets the job done great!
For the price you cant beat this amp. I installed it almost 4 months ago and it still works and sounds excellent powering my 4 pioneer 6x8 premiere speakers. As mentioned by another reviewer it does run hot.

Good amp for for the money!
This replaced a factory amp with factory speakers. Easy to install and works fine. Good for stock type applications - I have a GM monsoon that had a stock amp -where you are not pushing the speakers too hard - blasting days are over for me. I would recommend it as a good value stock repacement.
