Can I hook up these speakers:
Front: 42.7i(50rms) and 50.7cs (85rms)
Rear: 693.7i(110rms) and 52.7i(55rms)
All speakers are Infinity Kappa.
To this Amp:
Rockford Fosgate P4004
50 W x 4 @ 4 Ohms RMS
100 W x 4 @ 2 Ohms RMS
I think of connecting them in parallel;
front left / CH1 (42.7i + 50.7cs)
front right / CH2 (42.7i + 50.7cs)
rear left / CH3 (693.7i + 52.7i)
rear right / CH4 (693.7i + 52.7i)
This would result in an 1ohm load
but the amp put out 100 W x 4 @ 2 Ohms RMS
would it work any good or do I have to get the
T4004 that puts out 100 W x 4 @ 1 Ohms RMS ??
I guess I can't hook the speakers in series, cause I have crossovers to the speakers and therefore I will loose some of the Hz on the second speaker in the series, right? cause could I do it in series it would be a 4 Ohm load on each channel and I could run it at 50W x 4 @ 4 Ohms RMS...

All of your speakers should be 4ohm impedence, so wiring them in parallel will produce a 2ohm load. This will work fine for your application.

Nope, they all have 2Ohm impedance,

I ask this because I have the P4004 Amp, but if that doesn't work I have to get another.

I don't believe that amp is one ohm stable, so no, it wouldn't work...
------------- It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."
