First system, worked at first...

[SMolen]

Well I just built my first system. I bought a Kenwood KDC-205 h/u. Blaupunkt PCA1350 300w mono amp, and a Polk db104 10" subwoofer. Topped it off with Monstercables.

Well when I first hooked the system up everything sounded great, at one point in time though my power cable slipped out of the spade terminal due to an insufficient clamp. Shortly after I realized my sub would sometimes not be on occasionally, just for a few seconds. After a while I noticed that I had to turn the h/u up to a certain volume for the sub to kick on, and it would be fine unless I turned off the car or turned the volume down too low. Gradually that volume needed to get the sub to kick on became higher and higher, now the sub does not come on at all. It strangely did the other day out of the blue when I got in to go somewhere, and the only thing I noticed that was different was it was really hot in my car. Hasn't worked since.

Amp is green light whenever my car is on, no protection or anything. I just don't know what I'm missing. The ground wire used to be long, but I regrounded with a bolt straight to the chassis so I know that can't be it... AUDIO GODS HELP ME!

Its not my RCA's. That was what I thought the problem was, should've mentioned those Monstercables came earlier today. Hooked them up and still nothing.//content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

Next time dont buy overpriced cables and this wont happen.

Guess that was my bad. Any other suggestions? Fuses are fine too...

Get a DMM and see what the coil(s) are reading at. Could have blown the sub, somehow, and while you are at it, check to see if you're getting any output voltage on the amps speaker terminals.

Trigger wire shorting out somewhere?

Bad turn on signal from the deck?

 

[SMolen]

The turn on is hooked up to my cig lighter. If the amp turn-on were bad, wouldn't my light be off on the amp?

Check the fuse on your cig lighter....better yet wire it off the deck like it's supposed to be...don't know why you wouldn't have done that in the first place...if that fails run a wire from the power terminal on your amp to the remote terminal on your amp and put a switch in the line....then see if the amp will turn off and on with the switch? if not sounds like the amp turn on or deck turn on might be bad...
