I was going to listen to my system the other day, and i turned it on when it was just about to hit it kinda shut off and started making a weird noise. Kinda high pitched noise. I took the sub out and brought to another car an ran it free air so that wasn't it. Same with the amp. I replaced the auxiliary wires and it started to work on a low level. so i turned it up just a little bit. Like up 2. Hooked it back up.(keep in mind this is back in my car running free air to see if its going to work before i put it all back together) and then it sparked and stopped working again.

I have a 18" fi Bl, It was hooked up to my buddies sundown saz-1500d, and my Pioneer avh5000dvd headunit, Knuconcept 0 gauge wire. RF speaker wire and RF aux cable.

What sparked exactly? What are you grounded to?

The speaker wire to the sub spared. The sub still moves in and out freely w/o scratching of the coil. It's grounded to a bolt that is underneath one of my seats. The amp still comes on. The sub just isnt getting a signal. I believe that there is a short somewhere but i don't know where. I don't know why it would have just now happened when i have and the same ground for about a year. and the same basic setup since December.

Have you tried a different head unit or tried bypassing it?

Have you tried a different head unit or tried bypassing it?

No i havent tried either.

You didn't turn off the amp before you hooked the speaker up? Bad idea.

I unhooked the battery cable. I believ that it is the radio, i just sent pioneer a message. Hopefully they get back to me...
