mid range wiring

[yUmadBro]

i want to wire 6 6" cadence mids @ 4 ohms. they run 75 watts rms each so 6 will run at 450 rms. i want to wire it to a crunch 900.4. how do i go about wiring up six to a four channel? the crunch 900.4 dosent have rms ratings but the amp runs 4 ohms @ 115 watts per chan and bridged @ 450 watts x 2 chans. any help is appreciated and sorry if the answer is posted somewhere else i couldn't find it.

You can wire 4 speakers to your front two channels buy wiring then in parallel with each other. That will run the front channels of the amp a 2ohm per channel. You can run the last two on the rear channel, but the amp will run at 4ohms. You need to find out the power output of that amp running the fronts a 2ohms. If your lucky it will be 230 per. That way all of your speakers will effectively be receiving around 115 watts. It's unlikely that running at 2 ohms will double your power though. You may be able to reduce your rear channel gain to balance the power among all your speakers.

You can not safely run that amp bridged with all six speakers wired in parallel. It would effectivly place your amp at an unsafe impedance (< 2 ohms).

so what do i need a different 4 channel capable of running them at 2 ohms or another amplifier?
