couple of questions. real fast. lets say i already have a headunit. with only one set of rca's output. i want to power all 4 interior speakers. but not with a four channel amp. i want to power it with two, 2 channel amps. how do i do this?

also how do you know if the outputs are for full range or for a sub, etc.?
i think thats all for now. thanks,

 

add a High level to Low level converter, this will give you RCA for
every speaker outlet. Chrystal is the best. But you can get cheap ones for $10-20.

 

Or get a EQ with 4 channel out and sub out.... This is the way I
would go.

 

Jimmy - Alvin's ideas will work but if your H/U has a single set of RCA's U won't need a LLC. U can use a splitter on the outputs but U'll lose your ability to fade or balance ( depending on how it's hooked up ). I like Alvin's idea of an EQ ( preferably a passive parametric if ya want to really be able to tune things ). As far as the signals go, unless the H/U has a dedicated sub RCA output then those will be full range signals going to your amp. Use an external X-over or the amp's internal crossover card ( if so equipped ).

 

ahh thanks alot guys. u cleared some stuff up about the H/U's i dont have one, BC of rx300 display. but my friend was curious and askin me how it would work, and how to hook it up.

 

sprinkles just run the 2 chan amp at 2 ohm stereo works fine and its easy and ya only need 1 set of RCA's

 

Or bridge both amps to the front speakers. Screw rearfill...
