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

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.

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.
