deck shuts off when the stereo is at its loudest!?!
 

I have an alpine "glide touch" head unit and when I crank the stereo.. The deck shuts off then comes back on right away... What would be the cause of this?

System: JL - 1000/1, 2x 12"w6's, 0/1 gage, stock altornator, 1 farad cap.

could this be because of a voltage drop? (lights dim bad when I drive)

Triple check the ground to the deck!

Check the speakers, make sure the OHMS are correct. I had this problem and it was a blown coil of my quad coil sub

that would affect the amp not deck!

I will check the ground but the power to the deck is not to the battery. It's hooked up to the wire harness.

Hook it up,just like you would an amp,i used 10 awg from battery to deck,alot of alpine decks require this..
I never really noticed any major improvement,just slightly.

I should put a fuse from the battery to the deck right? If so, what size?

Depends on the size of the wire that you are running...

are you runing subs if not there wont be enough voltage drop to shut off the deck. most likely it is a bad ground i would just change that before you do anything if that doesnt fix it then just run a wire to the battery you can do this with power and ground. put a fuse in line with the power and try to keep it as close to the battery as possible use a 10 amp that wouls be fine.

your car has dogsh!t factory wiring, you need to run a new 12awg consatant powr lead to your ignition or battery if you cant figure the ignition out, just do it and be done with it
