My Rockford Fosgate subwoofer isn't working. I looked at one on eBay and the sub looks really shallow. I'd like to replace the sub, but does the factory RF 8" sub have a special connector or special slim depth? Also, since my sub is out, I might go another direction. I'd like to put in a new double din stereo with Android Auto and Apple Car Play. I realize to do this I'd have to bypass the factory RF amp and I also realize I'll only be able to power the door speakers and not the 8" sub but that may be ok. I might install better door speakers with more bass. I might even put a speaker box in it. I have a JL Audio amp sitting around and a dual 12" sealed box with 2 12" Memphis audio subs. I'm just trying to find out my possibilities right now.
