No power or protection light at all.i am very good with electronics,but i cant seem to find the trouble area on this amp.have checked resistors and heat syncs,which is the most common problems in car amps.and they test fine.any hints would be greatly appreciated.
Blue wire on deck usuelly need to be connected well .does the ground wire have a good connection no paint locking the frequency scrape it to metal.an drrect li.e to battery with fuse right befor the battery.are the wirers thick enough

First disconnect the CD head unit from the sub amp and see if the other amp works. If yes, the problem is the wires to the amp, the amp itself, or the subs/sub wiring. If no, the problem is the head unit--probably an internal short. If the other amp works with the sub amp disconnected, reconnect the sub amp to the head unit, but disconnect the sub wires from the amp. Try the CD player. If the amp goes to protect with no speaker wires attached, the amp is bad. If the amp is OK, the problem is the subs or sub wires. Hook the wires up to the amp again, but disconnect them from the speakers. Try the player again. If the amp goes to protect, the problem is the amp wiring. If not, the problem is the subs. Check the impedance of each sub using an ohmmeter to determine which amp is out of spec. Please let me know if you have questions, and thanks for using Fixya.
I'd need to know more about the amp, but don't forget, amps are rated as their max power... So lets take a 300W/channel stereo amp at 8 ohms. Ok, it's stereo, so there's 600W But the amp is capable of 4 ohm loads...well, now you can deliver 600W/channel, for a total of 1200W In this scenario, your amp is doing exactly what it was designed to do with those speakers. If you wanted to get the full 1200W out of the amp, you'd have to hook up 2 more speakers in parallel to the ones already there. This drops the impedance to 4 ohms per channel = 600W / channel. Yes, the power is split among the apeakers...300W per speaker into 4 speakers = 1200W so any way you look at it, there's your 1200W
i had the same ploblem with my amp then i found out i didnt have a good enough ground. Make sure you groung it to your weel well or some part of the frame. Or you mite be running with a fuse thats pushing to much power i use a 100a fuse 5 gage power cord to power my 1200w xplode and my 2 12" kicker comps. Or if your using two diff kind of subs then you amp is confused in why your asking for 500w on one side and 600w on the other this will also make your amp light come on.
If you've got a standard 4 speaker system (2 front, 2 rear), your best option is to connect both left speakers to the left channel amp output and both right speakers to the right channel amp output. The only thing you lose is the ability to fade the speakers front to back.
