Ok, so I had this amp I just got and it worked great for the whole day and I got everything tuned perfectly. Well I go to start the car and the light isn't lighting up, but all the cable's have power going to them and the ground is excellent also. No fuses are blown and the amp never smoked or went into protection mode and it was brand new hadn't even been run for one full day. It has 4 20a fuses on the amp that are all good and one 100a fuse at the battery that's good also in case anyone's wondering. Can anyone help me troubleshoot here??

 

Your turn on wire has power at the amp too?

 

Yup, remote wire has power also and there are no shorts in the wiring anywhere. This is driving me crazy, what could it be?

 

Doesnt sound to good lol. What kind of amp is it?

 

The amp is a Crunch GP1100.2. The amp is crap I guess and it's powering two Alpine s 10"'s. I payed like $100 for the amp which sucks and I really don't want another one at this point, so fleebay here I come... I'm going to be getting an Alpine MRD-M605 at this point and stay with quality components. I just don't know how it works and just stops working for no reason... no overheating, blown fuses, shorts, etc. When it did work, it sounded great and seemed flawless, just wish there was a way to fix it. Is a 100a fuse about right for the 12v cable from the battery?? Just trying to think of anything at this point... What else do you think?

 

Try a new ground and a new remote wire. I had the same thing happen to me I went to a new ground and its fine now.

 

It seems like the ground is good because when I screw the wires in it makes a little spark and if I touch the ground wire and 12v wire together it sparks also like it's got connection. Would the ground really go bad after working fine for a few hours and just crap out like that??

 

This is not a good method for testing to see if wires are powered.

However a bad ground will still cause it to spark, but may not turn on the amp. Check resistance on the ground and check voltage on the remote lead.

 

Yeah, I know it's not a good way for testing but I don't have a voltage meter right now and this actually happened by accident when I dropped the wires on top of each other before I taped off the ends so I didn't start a fire, but isn't it normal for the ends to spark once you screw in the ends for a split-second or so on the amp? I'm going to go clean the ground or find a new spot and report back, thanks for your help guys, hope the ground is my only problem!

 

Have a bit of patience and wait until you can use a DMM. Yes its normal for a bit of spark. You will also want to see what current is being supplied, not just if its there or not.
