I went and did the Avic D3 bypass yesterday, so that annoying message doesn't come up every time I turn on the car, and after I got everything put back my subs weren't working. I checked everything. The amps power light is on, fuse in power line is good, RCA's, Remote, everything is connected and looks good. I cannot figure it out. I went over every connection. It has to be something with the bypass I did, because they worked before that.
ANY input is greatly appreciated. I'M STUMPED
Thanks Guys
