this is a monster amp

I have had this amp in the back of my chevy caprice, the trunk leaked and even with the water from the rain i never missed a beat. I would recomend besides rockford makes top notch equipment. I would recomend this amp to anyone whether boat leaky trunk or car looks great in a car as well.

Great sound

Have only had for a few weeks but so far everything works great. The sound is much better than my old Sony amp. Clearer sound especially at high volume. The amp has plenty of power for my small open boat even in wind and at 30mph. Instalation was easy. Had to install heavier wire and a bigger fuse.

Giving it a second shot

Received it from Sonic installed it and it sounded excellent. It's been 1 year and 2 months and now the unit stopped working. The unit powers on but there's no output to the speakers. I have it installed to a Clarion M502 and 4 Polk Audio MM6501. I'm giving it a second chance and ordering another since the sound quality was so good. I'm really hopping this one last a long time.

Super Value!

Bought the Amp a month ago and I am very satisfied with both Sonic and Rockford Fosgate. Did not rate high for durability since its a brand new item for me.

Second try

I bought this product twice and the first one burnt up!! I reordered and the second unit works well but gets very hot!!!! Lots of air space around it!!! It will definitely crank out the sound!!! I have a all Rockford system the M1200 mono amp is great !!! 2 Rockford marine 10" subs 2 marine 8" and 2 marine 6.5 speakers !!! It sounds great!!!

Great Sounding Amp

Easy set up. Can run for a long time on a small battery. Does not get hot at all. Great sound have it hooked up to 2 sets of DC Gold speakers on a small (14ft) boat. Plenty loud even at 30 MPH.
