Anybody using this amp. It looks to be good but I have no experience with Pioneer amps.
Pioneer GM-X364

I was going to put this in the Miata so size is an issue. I am wanting to run the two door speakers and the 4 headrest speakers. Also, can you run a 2 ohm load on the rear channels of an amp and a 4 ohm on the front. The headrest have two speakers in both seats and they are wired in series. Any other suggestions if anyone has any for amps to fit this purpose.
