so i have a 2005 honda accord i took out my aftermarket JVC stereo and put new head deck alpine 122 and installed two frnt 6.5 speakers in the front doors i also have 2 jl W6 in the trunk, after installation i did myself i keep having my subs go off like not going with the song just a loud noise like its bumping and wont stop. i have no idea if it could be something wired wrong or something is shorting please help..

FYI i took it to a stereo shop he saids its my bass control **** being bad so he disconnected it but i still keep getting that noise like if my bass is just vibrating very loud..

 

Check the sub amps ground.

What is the make and model of the sub amp? 94

 

Im having the same problem

 

i figured it out with FCM help thanks..i found a loose wire close to the ground that might have been a good way to short out my subs and amp if i didnt catch it...
