I am looking to build a 6.1 sound surround system, I have experience building boxes, and alot of car audio install experience. I want to build 4 towers with 2 6.5"s a 4" and a 1" tweeter. using car audio speakers, most likely infinity kappas.
One center channel with 2 sets of components, and a powered 12 " sub. I want to be able to place passive crossovers on all mids and highs, but still wire the towers with all 4 speakers powered by one input, and have the correct ohms for the amp and speakers. The amp also has to have enough power to run the speakers at the correct ohmage, Is this possible, or just a pipe dream?????
Also where is the best place to buy internal amps for powered subs? I will need a
6-800 watt rms internal amp.
