Default Need some help.

I am trying to hook up a system in my wife's New Beetle. The HU is a brand new JVC, subs and amp are used Memphis Audio parts. Bought those from a family member, so I have heard them and know they worked when pulled (which has been awhile though).

Everything is wired up, the amp's green power LED comes on, aswell as the blue Memphis 'M', however the subs make very little sound, you have to be next to them to even tell. Now I have double checked the wires, tried another ground, tried new RCAs, tried another amp on these subs, tried this amp on other subs, tried other amp on other subs, all same results. The HU has a Sub on/off and I made sure its on. Played with all gains/ levels. Nothing is working though. Any ideas?

Do you have another speaker that you can connect to it?

I have tried another pair of Xploders on it with the exact same response. Very small amount of bass and can just barely feel the woofer cone move... also tried the Xploders amp on my Memphis subs with same response.

Try plugging the RCAs from one of the highs amps into the sub amp. Does that produce any output?

Mids are just HU amplified, but I did try running the RCAs out of the front and rear outputs on the HU with no noticible response from subs.

Check the shield ground on the head unit.

Ok, well I didn't try the shield repair, but I tried the headphone to RCA on the mp3 player Nd still no output.
