Audio Tech Question
Ever since I blew that fuse auto crossing last weekend, I havn't been able to get my subwoofer working again. It worked fine since I got it (used from dropout), but now something's wrong.
I have a Pioneer deck, Kenwood amp, and Kicker 10" sub. Simple setup, sounds good.
I first checked the back of the head unit. The fuse was fine, all connections in tact (including RCA cables). So I move to the trunk. I check the fuse on the amp (fine), the fuse on the power wire (fine) and the amp gets power fine. So it's not the power, it's the audio signal. I checked the RCA cables and they seem ok I guess. So I checked the speaker wire from the sub to the amp. While it was on I went to unscrew one of them and saw a small spark. I wiggled the wire a bit and I heard sound from the sub. Whatever I did seemed to work, so I went to put the sub back where it was in the trunk, but when I did, the sound went away. Since then I've tried "wiggling" the wires as much as I could but with no luck. I even cut off the old connectors and used new ones and crimped them super tight. Still nothing. My last thing to check before I go nuts is to take out the sub and check the connection from the inside.
Other than that, do you guys have any other ideas?? I really don't want to run new RCA cables. Thanks.

well you can start with a diag on the sub. Do you have a multi-meter? set it on ohm and connect it to the connections on the box and depending on what ohm rating the sub has or what you set it at you should see that reading. If it is showing nothing and you push in on the sub and the reading shows then you have a blown sub. So no fuses are blown anywhere? keep me updated

I still havn't had a chance to take a multimeter to the sub, I've been super busy.
But biggie5252, to answer your question I blew one of the radio fuses somehow. Go figure.
