Just bought the Pioneer GM-7300M. Have all power connections hooked up...receiving power from battery and remote...amp will not power on. Was testing the connections and when I unhooked the rmote turn on and touched it back to the hookup the power light flashed on. Any ideas?

Hi there, check when you have switched off the power in the car to see if the amp power lights are still on, if so there could be a problem with your remote wire. Check the cables to he rear of your stereo and with a test meter, determine which one loses power when the ignition key is removed. When you have found this cable, splice your remote lead to this one, and your amp should switch off when you switch the car off, thus saving your battery. You could wire it to a permanent live feed and install a switch to allow you to run the amp without the key in the ignition but dont forget your battery will run down fast because Amps use a LOT of power.
i doubt its the rca cable. check the connections from the back of the head unit, also check that you didnt blow any fuses either from the wire from the battery or on the amp also check the remote wire (little blue wire) and make sure its grounded really well
Make sure your power line comes directly from the battery and that iyt has no abrasions or cuts in it. Check your ground and make sure that it has a good connection to the vehicle chasis. Ensure that the remote line is connected properly to the remote lead from your head unit/receiver.
Common mistakes in this area are using the remote turn on lead as a power lead. It does not have near enough power to drive the amp so you will only get a slight trickle of power.
With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.
If the voltage on both terminals is 12v or higher, the amplifier may be in need of repair.
Buy an amp wiring kit. The battery cable goes to the battery (duh, right?) with the fuse within 18 inches of the battery. The ground gets bolted to a clean section of the car chassis/body. the remote lead goes to the radio's remote out (blue/white stripe). the rca cable goes to the radio's Sub/rear RCA outputs. Speaker wires go the speakers. Done!
This may have a different type of triggered turn on wire. On some of the older Pioneer amps (and maybe some new ones) the trigger wire would SUPPLY B+ TO THE RADIO and when the radio was switched on the amp would sense a current draw on that wire and would then switch on. Unlike most common amps which sense the presence of B+ on the trigger wire supplied by the radio and then turn on. Look in your owners manual to see kind of turn on system you have. If you don't have an owners manual then perhaps you can download one from Pioneer support.
