My amp cuts off every time I turn it on.. even with n without the wires connected!!!! N if I do cut it on the volume is on -7 n cuts off automatically n won't come back on unless I replug n plug it up...


Does the "protect" light turn's on when it shuts off? If it does then theres a problem with your wiring or worse this might be a Thermal Protect. The amp shuts off because its lacking of voltage from your battery & alternator. Post your system so i could help you further.

I have my new HK3390 hooked to my legacy Polk monitor 7s. The Ohms and Wattage match pretty well. I have the positive hooked to the positive and negative to the negative. I only get a tiny bit of sound...


Never troubleshoot anything with the volume cranked up. The moment you find the mispositioned control you'll damage your speakers. If something isn't audible at half volume there's a problem.

Are the speakers activated?

Check that MUTE is not turned ON.

Make sure you don't have any Tape functions selected without a corresponding device attached and functional.

DTS Master HD audio problem


Hey! Make shure your amp and blu-ray player output and input signals are set to "bitsteam" and you are useing HDMI and optical connections. I hooked up my Onkyo tx sr 506 integrated amp to a Samsung BD 1400 player and everthing worked perfectly right out of the box. Perhaps your amp can"t decode DTS HD Master or your blue ray doesn't support it although i think a firmware upgrade may accomplish this. Put on The Chronicles of Narnia Prince Caspian which will DEFAULT to DTS HD MASTER 7.1 and see if it works. It's an excellent source to test your system. Picture and audio recieved 5 stars from Home Theatre magaziene and like i said, either your amp, or player doesn't support it or your interconnects are keeping it from coming thru. HDMI and OPTICAL connects and check your set up for "bitstream" Remember what Todd Rundgren allways said,"Everything will work if you just let it!"

Sound problem


Make sure all speakers that are hooked up sound ok. If any of them sound lower then the others or sound distorted you may have a speaker with a partially shorted voice coil. If speaker or speakers pop when power is first applied you may have a grounded speaker that should not be grounded. Each speaker wire rides on 6vdc and if any speaker sees a ground you will have 6v across voice coil which would explain any popping noise when first turned on and radio may play for awhile then overheat. be sure speakers are 4 ohm min per ch otherwise amp will run to hot. Just a few Guesses

Yamaha SW118V Subwoofer


NICE SUB! I have found that when this happens, there is a good possiblity that there is a loose connection on the speaker, or on the crossover network inside the sub. The real only way to test this sub to see if it is indeed the sub, would be to test it in real time under controlled conditions. That would involve hooking the sub up to a power amp that has a tone generator attached to the input and driving the sub to its rated capacity. Other then that, you could probe around to see if you have or can see any loose connections inside the sub BUT I would not recommend you doing this while the amp is on as you could short out the output stage in the amp. My best advice would be to take or send this sub into an authorized Yamaha repair station. Good Luck
