Ok I got a new deck an Rca jack's, think it would keep my amp from shutting off. But it still doe's, My old deck would dim in an out evertime a bass note would hit even with the amp off an I couldn't turn it up past 20, an with my new one I can't turn it up past 25. An if I turn the bass up on it, it sound's like it is skipping while it's on just the radio. So I'm thinking I need A. New Battery an Alternator or B. New amp kit. Now my car's been sitting for a while so It' need's charge but before it was still shutting off. can somebody help please.

Do you have a volt meter? Your problem is a lack of current getting to the yellow wire of your radio. Or not a good enough ground for your radio. With the radio playing loud enough to make it "Skip" you need to check the voltage on the yellow wire of the radio. When checking that, you need to ground the black lead of the meter to the chassis of the radio. When checking that you need to ground the black lead of the meter to the chassis of the radio. Notice the lowest reading you saw on the meter. Now ground the black meter lead to another ground location, notice the lowest reading there. Post what you find.

Ok on the chassis it ranged from 13 dropped to 6 an then to the car in dropped to 8. I notice though while playing if I shut the door it would shut off.

You need to connect the yellow wire of the deck directly to the battery via a 12 AWG wire with a fuse holder and a 15 amp fuse where it is connected to the battery. You also need to ground the radio's black wire to the chassis of the car. Your radio is not gettting enough power.

Did you attach the radio's black wire to the chassis of the car?

is it screwed to bare metal or to something that has paint on it? you need to scrape the paint off the spot where you attach your ground. -------------

Ok So I've got the deck to stay on, My amp still shut's off though, I think I need to run new power cable's an remote wire.It' will hit a note an shut down like I don't have a good ground but I scrapped all the paint were it is screwed in at, My amp can take 4 gauge wire I got like 8 or 9 gauge hooked up now, Do you think I need the 4 gauge.

Take your volt meter and check the voltage at the terminal of the amp. Black lead on the ground terminal of the amp and red lead to the positive terminal. You must have the volume up close to the point of the amp shutting off. You must have the black lead on the terminal of the amp, not to the chassis of the car.

im having the same issue kinda, when i turn my radio up loud, it shuts off the radio. I found out that if i unhook my rca from my sub it doesnt turn off. Try testing your remote wire and see if that voltage drops

I thought it maybe the remote wire too.So do I just hook it up red lead to the remote an black lead to the ground.

use a voltmeter to test the voltage on your remote wire. your remote wire should stay at 12 volts

Ok I forgot to mention that about four or five month's ago I had some issue's an I got my license takin away, so I let my dad take my car, before he took it I pulled out my amp an sub, I disconnect the power from the battery an the ground, but I left the rca's an the remote connect. Well when I got my car back I got new rca's. So I pretty sure it's the remote since I've replace the rca's. Stupid of my part to leave them connect, So do you think that could be it?
