Amp humming, Autotek sx1200

hey dwarren. thanks for your tips. very helpful. I may have misled you or you misunderstood me-the hum comes from the subs not the amp. its just a 40-50hz constant tone that starts when the volume on the deck goes up-doesnt increase with volume or rpm and dont stop until the amp turns off. When I turn it back on its ok til the volume goes up and it gets stuck on 'hum mode' again. Hope this helps you visualize this. how would i hear a hum with the speakers not hooked up unless it was the amp itself-its not the amp humming its the subs. Thanks againWhat the feezy?

i never got to check it like that...never thought of it..i just replaced the rca's to better ones. it only happend after i got the new cd player so that's where i started from. but i don't have any EQs or anything like that. just the cd payer going ot the amps then going to the subsTri County KustomZ

Maybe it doesen't know the words...... This may help... It won't be the subs. They just can't up and produce sound themselves, so that rules that out. It is coming from the amp. 1) Disconnect the RCA's from the amp- does it still do it? 2) If so... it is the amp. 3) Plug RCA's back into amp, unplug RCA's from deck. Still doing it? 4) If so, then check the RCA's, they may be pinched somewhere. 5) Try another source.... do you have an iPod type device that you can plug directly into the amp? This may help somewhat... Gus Wherever I go, that is where I end up......
