HELP!! Only One Side of Speakers Work on 1993 with aftermarket amp and subs

[jd92887]

i Just put in a new pioneer headunit, and a pioneer amp with subs.

The Left side Speakers work, but the right dont.
When i balance the Speakers to the Left, nothing works, Balance to the Right and the Left Work only.

When i got the car, there was already an amp bypass, so i didnt install the one i got with my other harnesses.

Only One Sub works too.

Any help would be appreciated.

got the door speakers figured out, but now one of the subs seems weaker than the other.

Does the subwoofer amplifier have dual gain controls? If so that could be the reason...

Are the subwoofers wired up exactly the same? You don't have one set of wires crossed accidentally, leading them to be outta phase with one another? It's also worth checking the RCA wires to see if the signal they're presenting are the same or not.

What was wrong with the speakers in case someone has a similar problem and searches for a fix?
