I don't know the problem, because I've never wired up subs. Do you have secure connections with all your wires?

First thing you need to do is see if your amp is even turning on. With the stereo on, what color is the light on the amp?

Might be a dumb question, but have you turned up the gain on the amp? Lol

This may sound like a pain to do but this is a diagnosis thing. Pop one of the subs out of the box. Using NEW wiring, run a wire directly from the amp to the sub (this will test the wiring from the amp to the subs in the box) if the sub plays, bad terminals or wiring, if not possible other issue.

If it doesn't play, tap into the rear speaker wiring and run a wire from the rear speaker wiring to the sub. If it plays, you have other issues, if not, that sub is blown/bad.

Also, check on the amp on the setting switches, are you running on LPF?

Which model amp/head unit do you have? May be able to look further into it if Iknew that.
