I'm trying to install a 4 channel amp. Here's the specs of the existing car:
'96 Honda Accord Sedan
Pioneer DEH-P9200MP <--It has 2 sets of RCA pre-outs.
MTX mono amp and 2 12" subs

Front Speakers: 6.5" Alpine type S (80w RMS each)
Rear Speakers: 6x9" Alpine type S (85w RMS each)

I bought a power distribution block and all that too.
I bought an Alpine MRP-F300, it's rated at 50Wx4 at 4ohms and 75Wx4 at 2ohms.

Now, I want to run it at 2 ohms. I know for 4ohms I'd simply run a pos and a neg wire from each channel to 1 speaker.

My questions:
1.) If I "bridge" the connection from front to back or left to right, will I be at 75w RMS per channel or way over that? I don't want to blow the speakers or amp here.
2.) How exactly do I bridge the connections for what I want to do? I've searched for wiring diagrams and everything for hours but couldn't find anything that makes me feel confident enough.

Thanks a lot.

You have a 4 channel amp, you have 4 speakers, why would you want to bridge the amp and wire the speakers together for a 2 ohm load?

The amp is underpowered for those speakers, the MRP-F600 would have been a lot better.

You could bridge the amp into 2ch, [2x150W RMS into 4 ohms] connect only the front speakers to it, keep the gain down a little, keep the rear speakers on HU power, SQ will be much better.

Better bet would be to swap the amp in, pay the extra, and get the MRP-F600. 94

your amp CANNOT handle 2 ohms bridged it will blow out. in addition, the power with the 4 ohm load is enough to run those speakers. they're pretty efficient, you're going to have all the bass on your sub anyway! Its really all in a good tune.

If you wired your speakers in parallel (2 speakers per channel) you could get 2 ohms, but then that 75 watts would be split between the speakers. Usually the only time people use an amp on a 2 ohm load is if they want to hook up, say, six speakers and bridge the last 2 channels at 4 OHMS for a small sub...
