I PUT AN AFTERMARKET RADIO WONT POWER UP.

check for power at the terminal end that connects to the radio. if yes then there may be a fuse inside the radio itself. this may have blown.

sounds like theft proof issue. Make and Model would help.

Easiest and best way to put a aftermarket radio in any vehicle is to buy a radio plug adapter at Walmart for $10. No factory wires cut just wire the plug to the radio and plug it in.

The motorolla box may be remnants of an old disk changer for the stereo. With an amp your power wire goes into the positive wire that goes to your battery, your ground wire will be connected to some bare metal close to wherever you decide to install the amp, and the blue remote wire will be connected to the remote wire that in on the wiring harness of your aftermarket radio ( I'm sure your not installing an amp with your stock radio). Good luck I hope this helps

Hey man, you have an amplified system. use a 70-1858 wiring harness and jump the blue/white wire from the aftermarket radio to the pink wire on the second plug. this will power on the factory amp with the aftermarket radio.

Chris-

You have a power wire going to your on off switch you should also have a power going to a memory wire to keep your stations and clock intact.

If the problem is no crank, could be the security system, key switch, neutral safety switch, starter, cables, or battery.
I would check for power at the starer and work back.
Did you try it in neutral ?

I have the same problem. I found that the stick shift wasn't locked in park possion. Once I locked it and turned the key to off the radio turned off.

most aftermarket units have 2 power wires 1 for the battery and 1 for a keyed hot source,what you need to do is hook both of them up to a constant (battery) power source,be sure and include an in-line fuse.

could be a fuse link. when you replaced the battery, did you put back all the wires ? fuse links are connected directly to the battery positive terminal.

check also the ignition switch, sounds like an accessory contact problem.
