Pioneer GM-7300M Car Audio Amplifier Logo
Anonymous Posted on Feb 25, 2010

My pioneer gm-7300m recently stopped working. On occasion, like when i start my car, it will cut on and play normally for a few minutes and then it will just turn off. I have no idea what could be causing this as I have checked all connections and I'm still completely baffled. Please help

    I actually figured out what my problem was. The in-line power fuse was blown...but not due to excessive current. It didn't look like a blown fuse. What happened was it was resting on part of the engine, exposing it to high temps, which in turn corroded one of the ends. it still looked fine, but if i tapped it, i could see a dust like substance in the glass. Hope this helps

    brwnmfb4ever That was the problem thank you very much for following up. I did not go to that inline fuse because the amp was still getting power. Turns out it was only getting power still because of the way the fuse blew it was allowing power through. Thanks again brwnmfb4ever!

    Wow over a year later I blew that inline fuse again. I guess if they last over a year it's not so bad. Well I thin I will run to the store and get a new inline fuse assembly to go with the new fuse this time. Just to clean it up a bit.

Had the same problem my pioneer gm 7300 amp just cut out day and never worked again, but it's pulling power like it wants to play but doesn't. You can here it trying to push out power with very little sound here and there but that's about it. Very thing is hooked perfectly no fuses blown and the light on the amp is still blue. If anyone has an answer I would great appreciate it

Your subwoofer has gone bad. It is shutting off the output which is causing the red error light to illuminate on the amp and send it into protect mode.

You need to clean the IAC again and also the throttle valve and bore, use only CRC brand Throttle body cleaner. After they are thoroughly cleaned disconnect the battery for 5 min's and then drive the car in varying condition for a few days. If that doesn't cure the issue you have more serious problems and will need a scan tool to look into the readings from the MAF, TPS and ECT sensors. High idle cold start is normal then slowly dropping after a few minutes. I assume you never had a check engine light. Correct?

I got a 800 watt amp from my friend and he didnt have instruction

What's the exact model of your amp? For taking the higher frequencies/treble out of the subwoofer, the amp should have a little button on the side that says "Hi Pass" or "Low Pass" or maybe an adjustable knob-thing that says "X-Over". These will set a cut-off frequency for your sub output. Some amps don't have this feature, but many do.

My GM-7300M anot woking

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.

Let me know if you have any other questions.

Installation

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!

No power to amp

Are you sure it has the full voltage going to both BATT and REM? sounds like the REM signal is weak.

Pioneer GM-7300M 800 Watt amp will not power on

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. good luck
