Amp gain won't set high enough.

[Mustangfreak]

New to the forum and really would appreciate some help

Seriously dumbfounded now.

Have a set of Rockford fosgate p3 12s hooked to a Rockford fosgate 1200.1d amp.

Was working great and slamming hard.

Took my trans out to put in a new clutch and got car back together and subs quit hitting.

Unhooked battery during work so never shorted any wires.

My issue is now that I cannot get my gain to even reach half what it was.

I set it at 34 which is the square root of the 1200 I was running. The subs were wired down to 1 ohm.

My head unit set at 3/4 way 26 out of 35. I just need some advice or maybe someone that has already had this problem.

The head unit probably reset. Go in and change the sub level back to where it was.

Does the amp work at all?

What voltage are you able to get out of it? Possible headunit setting from the battery being unhooked. Check all sub settings in the headunit.

Los got it. Once the power has been removed from the HU, everything gets set back to factory. Gonna have to re-tune the HU again. And then get back to us if everything is A-ok.

Yes powers on and checked voltage.

HU sub settings. Level, filters or both

I will do. I'll get back with y'all tomorrow and let y'all know. Thank y'all so much for the quick replays.

Hey guys. Recently checked all the settings. None of that worked. But I'm going to do a total HU reset later today. It's a Kenwood.

Hey y'all. Sorry I got lost in work. Ended up being my amp. Luckily still under warranty. Got a new one and got the power I needed. Sounds awesome again!

Thanks again you guys!
