Question about possibly blown amp

[Jakeeck 10+ year member]

I accidently touched the power wire to the ground wire and it sparked... Now the amp (hifonics) has weak lighted lasers and only the hi of hifonics lights up and it doesn't put out much power. But my amps fuse is perfectly fine...how can I blow the amp without affecting the fuse?

Did you let any of the smoke out of it?

not sure what that means... If you mean smoke coming from the amp there was none

oops probably blown a ground trace

Recheck all you wiring/connections/grounds, if they all check out, you probably burnt part of the traces in the board.

I have a rockford 4004 that my friend did the same thing and it did'nt blow any of the fuses and its stuck in protection. I buy blown amplifiers to repair, it sounds like you burnt some traces on the board or you fried the internal circut protection. PM me and I can help you out more.

what other wiring would i be checking? my amp worked fine before i touched the 2 wires on accident.. so i know my ground was good.. but i also double checked every connection physically connected to amp and all of them were still on good.. and then i even re-did the remote wire connection to my HU and still got the same thing

if i did burn traces.. is the amp done? or is there something i can do?

open it up and look for blown traces on the circuit board. probably in the power supply.

if i open it up does that void any chance i have at sending it back? i just got it a couple weeks ago and they said i could send it in for a new one but if i can fix it easily myself without voiding any warranty then id like to do that so i dont have to wait another week or so.

send it back if they will take it. don't know if warranty will cover that.

x2 send it in and be DOUBLE careful next time you connect it. Remove the fuse up front by the batt before making the POS/NEG connections at the amp. Then put the fuse back in...
