Hey.. Question for the Audio System Gods here...

If I have a four channel amp with built in bridging to two channels, is there a way I can then bridge the two channels to one channel without causing impedance problems? I went from a two sub configuration to a one sub, and I'd like to get a bit more life out of my amp before I have to replace it. Right now I have the sub only running on one bridge channel and would like to use both, as fas as I know, I can't bridge it again without causing impediance problems.

Dan,

I wouldn’t advice bridging the two channels into one. Keep in mind that most amplifiers need to see a 4-ohm load when bridged to mono operation. To be sure, check your manual. Most amps that I know has only a 2-, 3-, or 4-channel output and 4-ohm stable in bridged mode. What kind of amps do you have? We can probably help you a bit more if you can tell us what kind of amplifier you are working with.

Be careful whose advice you buy, but be patient with those who supply it. posted_image

It's an El-cheapo Pyramid 440 something. like 1000WATT total peak output. Four channels with a built in bridge to two channels. I know I'l eventually get a better amp, but I don't have the $$$ at the moment and am looking for a cheap way out.

Thanks,
