Default Amp not powering up (new install)

Sorry to keep bugging you guys, but I've got another issue with my system install. I've got a Pioneer amp powering my stealth box sub, and the amp is not turning on with the system. Using a volt meter, it is getting the same voltage as the battery, so I would think it must be either a fuse on the amp (looked fine), a setting in the JVC unit (can't find anything), or the remote wire. I connected the remote wire (from the amp) to the blue/white wire coming off the JVC head unit that was labeled "remote out". Is this correct? Is there anything else to check? I'm out of ideas.

Run your remote wire to the vehicle remote input prior to the unit instead of the head unit output and see if its the head unit giving u the problem......

Hi Matt,
Does that remote wire on the back of the radio connect to the yellow wire on the stock harness. If not try connecting to the pin for the yellow wire on the stock harness, not the harness adapter. The yellow wire on the stock harness is ignition controlled power and will turn the amp on and off with the turn of the key assuming everything else is right which sounds like it is.
Others can use the pink wire in some instances which is the power antenna wire but the JVC unit turns the antenna off when switched out of radio mode which will effectively turn your amp off also so you can't use that.
I'm pretty sure that's your problem!
-Ian

since you have a voltmeter, at the amp connect volt meter between the remote wire and ground and with radio on you should have 12 volts if remote wire is properly connected

Use a Volt meter, but make sure your ground is good also.

We got it working! The remote line was cut/damaged somewhere along the way when he installed it. He tested it with his volt meter and determined that there was 12volt power going to the remote turn on wire in the rear of the unit but no power between that and the amp. Gave him a call when I saw this posted to see if I could help (he bought the system from me), he's up and running!

Ian (Kee Audio) is awesome. I've never had a vendor go out of his way to help. I'm impressed and would recommend him to anyone. Plus, the system he set up for me sounds great!
