I replaced the center console subwoofer in my 04 sahara, and still not getting any power to it. I looked at the fuses and all were good. Im assuming the amp is blown, does anyone have an aftermarket suggestion that fits in the console? Also is that amp tied to the speakers as well? Ive noticed the sound is pretty subpar from all 4 speakers, PO isntalled pioneer speakers and pioneer HU. Just wondering if the amp would fix things before I go replacing speakers. Thanks!
