Excellent! December-08-10
Reviewer: Mark from Chicago, Il  
Perfect with my JL W0v2.  Installed in a Ford Escape and the bass is plentiful.  Amp is small
enough to fit underneath most seats.  'The included bass knob makes quick adjustments
easy.  
Some cons:
The adjustment dials weren't perfectly aligned but still work.  Wish the inputs were signal
sensing.  And why not Class D?  Nonetheless, good value & quality.

I'm using speaker level inputs and the amp sounds good. With an aftermarket reciever,
this amp will sound great!


 
came as a package deal August-21-10
Reviewer: Eric from Boston  
This amp came as a package deal with a 10"JL woofer They are both on the low end of  price, the lowest end of JL I believe. When I first Put the sealed box together wired the  amp and installed it all in my F-150 club cab I was ticked. It sounded as if I did nothing. I  first thought the amp was not on, it was. I checked to see if the wires came off the  speakers, they didn't. Then I looked at all the knobs they came from the factory all the way  down. I turned up all three and it came to life. I listen to all types of music and anything I  played sounded so much better. My Kenwood goes up to 30 or 35 but I highest setting I go  is 26 and it pushes my woofer quite well. Now I am chasing some rattles in my cabin. You  cant get a positive without a negative. The amp stays extremely cool I was expecting it to  get hot but it's not. I do recommend it to anyone the price is good and JL is a good brand.

Before I installed the amp and sub. I put in Boston Acoustics SC85 5x7 front and rear with  a JVC 100watt amp its sound so much better with the sub hooked up but the amp gets hot  this is my guess why I got it free with the pair of speakers I got. I gave this four stars  because this is all I have used to me it is a great package for the money you cant beat it.


 
Very Nice May-07-10
Reviewer: mcsewnab from Green Bay, WI  
I chose this amp based on research. I am running a single JL 10W1v2 with this amp in a Dodge RAM. I have limited space and the box I have the sub mounted in has .69 CuFt of air space. All I can say is that this combo sounds better than I could have expected. The single 10" sub hits hard and this amp has plenty of power to drive it. I felt the amp after a 30 min drive with the volume as loud as I can comfortably stand it and it was barely warm. I am 100% satisfied with this amp's ability to push my sub.

I am in my 30's so I am not looking for competition sound levels but I can say that this combo does shake my mirrors. The sub I am using is 4 Ohms so the amp runs at 175 watts. This was the recommended safe wattage listed by JL so I didn't see the need to get anything more powerful.

I am also running an Alpine CDA-105 for a head unit.
