There are a lot of different options. Here are a couple options for you I would consider. Active 3 way setup. First 300.4 amp, Channel 1/2 tweets, 3/4 midrange. First amp would be channel 1/2 & 3/4 on the processor. Second 300.4 amp, bridged channels 1/2 and 3/4 to operate as a 2 channel will be channel 5/6 on the processor. And the sub amp will be channel 1/2 (channel 7/8 on the processor). Option 2. active 2 way setup. First 300.4 amp. Channel 1/2 tweet (channel 1/2 on the processor) 3/4 midbass (channel 3/4 on the processor) Second 300.4 amp channel 1/2 rear fill. (channel 5/6 on the processor)Channel 3/4 unused(channel 5/6 on the processor)Sub amp channel 1/2 ( channel 7/8 on the processor.)
In order to do a ten speaker setup you would need to run the front doors and tweets off of the passive crossover that came with the set. Channel 1/2 on the first amp. Dash speakers, channel 3/4 on the first amp. Second amp. Channel 1/2 rear fill, channel 3/4 unused. Sub amp, channel 1/2 for the subs. That's the only way I see having a ten speaker setup without moving to a processor with 10 or more channels of output. Hope this is not to confusing.
