Thread: Adding subwoofer to 2ch output?

Thats called a crossover or a filter. A lot of amps have a high pass or a low pass filter on each pair of channels, this ramps down and cuts the frequencies below (or above) the level you set on the dial. For a sub you want a low pass filter with the dial set somewhere below 300Hz (hard to be exact, depends on your other speakers, your car, you speaker etc)

I dread to think how you are getting your rear speakers from one channel of an amp- you dont like stereo I take it? While a sub would work from an unused channel you wouldnt be able to use any onboard filters, youd need a separate crossover. It would be best to get a dedicated amp for it.

Thanks in advance for all your help.

a splitter would work yes

Actually I think the rear speaker are wired like that. Whenevr I hooked up either of the rear speakers (right or left channel) they bouth made noise. :-/
