alright, so i disconnected my subs and amp for a while before i took my car to the shop to have a new clutch installed. after i got my car back i hooked everything back up and im not sure whats going on but the subs are really quiet. not sure why this is happening. the subs use to hit really hard and now it they just have no power at all. could either the amp or subs be blown? i did get a new fuse for the power wire. thats the only thing that has changed.

 

are they in a shared airspace box?? try unplugging one speaker. if it gets louder then one was hooked up backwards.

 

both 12's are in one box but its separated in the middle. ive pluged it up correctly with neg going to neg and positive going to positive. just is really quiet. i did switch the wiring aroud and i got one sub to get a little bit louder but still is quiet. thease subs were super powerful before. do you think anything is blown?

 

you check the gain on the amp? and or balance on the deck and or front/rear fader?

 

yes, everything is set correctly and i just tested my subs with a multimeter, the subs are fine. perhaps the amp is bad

 

they are probably out of phase with eachother. try flipping one of the terminal wires around.

 

the amp should not be bad from you just taking it out and putting it back in.

 

did you accidently adjust a crossover frequency or push a mono/stereo switch?

 

check power and ground to the amp, sounds like its just a wiring issue and nothing is blown because they were just unhooked
