No Sound from Subwoofer
The original Pioneer subwoofer has its own amplifier built in to the speaker, so the only cable required on the original speaker is a single RCA cable. To connect a different brand subwoofer to the Pioneer you will have to make sure that you have a subwoofer with the same specs. It will need its own built in amp to work, as you can only connect it with one RCA
i didnt meter test the amp yet
have you meter tested the amp ? its probably blown
