Rockford Fosgate Marine Amp
Runs 600 watts to my cadence comp 6x9s
Beast set up

Compact but Powerful
I bought this amp to put in a bass boat and I was very surprised when I opened the box. It's a very small amp and I had no problem mounting it where I wanted. It runs cool and powers my speakers with ease. My birth sheet said 507 watts.

Ole school
The ease of use and install, the look and design are awesome, the output is consistent and clear. I matched it with the rest of my Rockford Fosgate stereo. I am happy with it

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.

AWESOME!
This amp is AWESOME! Sounds great! Comes with a certification saying my serial unit was tested to 536 RMS. Would highly recommend.

Good sound, small package
I have this amp pushing a pair of RF 262s and a pair of RF 282s. Much better sound than my previous MB Quart amp (and that one didn't sound bad either). Time will tell how it holds out - only 3 stars on durability because I have only had it for a few week no, but 0 issues.
