alot of power for highs! i loved it! just got it so i can't say to much cause my i'm waiting to get the Rockford Fosgate Symmetry EPX2 w/28 band EQ card! then it's going to be off the hook!

it gets kinda warm. but who cares, your not going to be holding it! this is not a weakness! i have had rockford fosgate amps before and it does get hot but it never shuts off, i repeat never shuts off!!!

i got this amp for a steal... i have this amp pushing my highs... it works great! i got the soundstream spl 6.5" and they scream!!! pretty nice, i need to get the Rockford Fosgate Symmetry EPX2 w/28 band EQ card then my system will be excellent! i can't wait!

This is a great amp. I've used it everywhere in my system. It ran my highs for a while, then I used it for my subs. Better put some fans on it though, It gave me third degree burns on my vagina.

poor design and tech support

my 800a4 has been junk out of the box it can''t filter the noise from my ford f-350 powerstroke i have had it all over and tried everything. I replaced it with a cheap Pioneer and it fixed the problem.(only after it went to the factory twice)

Power, reliability, appearance and bass adjustment knob.

Amp gets HOT when driven hard, but doesn't cut out unless you have it in a inadequately ventelated area.

Have been using Fosgate amps for years and this newest amp hasn't let me down. If you hear someone complaining about power output from this amp it is because they don't have thier system configured right. I am using the front channels of the amp to run a pair of a/d/s/ 336im speakers and the rear channel is bridged running a Kicker S8L7 woofer. The system is in a 2000 S10 regular cab and it is LOUD!!
