I have a setup where im using a rear speaker as an input to a 1800watt Kenwood amp. everything runs fine and no probs. just wondering however, i can unplug or plug in the factory sub, i usually leave it unplugged because of my 2 12's so when i have it unplugged, will the amp auto-direct the watts it would be using to the rest of the speakers? or does it leave the same amperage to each speaker and just not direct any power to the sub. also im wondering why, (my other Cobalt did this too) as soon as you turn on your stereo and have the knob turned just once so its at the lowest volume, you hear static noise and the music itself but very very low, the static noise is louder until you turn the volume up high enough it kills the static.

 

Yes...........

 

The power distribution will remain the same whether the sub is unplugged or not. The speakers are on seperate channels from the subwoofer.

Your getting static because your plummed into the rear speaker line, by the time the signal has gotten to the rear it is usually pretty dirty. Your only choices are to grab the signal earlier near the front of the vehicle with better speaker wire, run your High to Low up earlier at the front, or go with an aftermarket deck. I'd go for the latter...

 

On my other Cobalt they Did tap into the front and i got the static, this time its rear and same static. im thinking its just on all Cobalts, a very light staticky at the lowest volume. otherwise the setup i got is awsome.

 

sadly you always run that risk with a hi-low convertor. The only real fix is an aftermarket deck. I attempted a Hi-Lo when I first got the car and got nothing but static and alternator noise.

 

Good grounding is key as well, since it will help reduce your line noise. But any Hi-Lo will have some static.
