Was the amp in working condition when you bought it?

Try double checking your rca cables from hu to amp.

the seller said its in working condition, and i double chcked all wiring and rca's like twice. the guy said he would give me a refund if it didnt work though, so we'll see if i could figure out what's wrong.

Check fuse too...sorry having a brain fart on this one.

make sure the sub is turned ON on the pioneer... other than that check for 12v on remote... 12v on battery... make sure it's grounded fine... and meter the sub at the amp with the amp off and see what it reads

what's "phase control" and how do i check the fuse on this amp?

 

[Slody4Futbol 10+ year member]

leave phase control set at 0... and to check the fuse... pull it and look at it... is it blown?

press the reset button on your subwoofers motor structure

Might sound retotted, but play with the gain control, (turn other way)?//content.invisioncic.com/y282845/emoticons/banghead.gif.8606515f668c74f6de0281deb475b6fd.gif

put a DMM to the + and - of the amp and see what it reads with the car on and music playing

Measure the remote and power w/ respect to ground ofcourse //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif. Also check the output (speaker channel)and see if what its reading there.

edit: found the right one to open it. now i dont see the fuse x_X, also everything looks fine..

Maybe you have the amp bridged wrong.

the fuse(s) will be on the outside of the amp... like on the side probably close to the power terminals...
