Building a new system


Unregistered guest
Okay, I started off my car audio system by replacing the factory speakers. Heres my intended setup:

Front Speakers
Infinity Refernce 6012si Shallow mounts
50 watts @ 4ohms RMS
150 watts @ 4 ohms Peak Power

Front Amp
Alpine MRP-F200
(40 watts x 4ch. @ 4 ohms RMS 75 watts peak power)but will run it at 100 watts x 2 ch Bridged 4 ohms RMS @ 180 watts Peak Power

Which Comes to question #1. Is the Amp too powerful to run these speakers in 2 channel bridged mode? Should i just run the amp in 4 channel mode and power the two front speakers or both the front and rear?

Rear Setup
Alpine SPR-69LP
55 watts RMS
275 Watts Peak Power

Amp: Orion 500.2
RMS Power at 4 Ohms 125 W x 2

So whats the best scenario for me to run here? I don't want to go out and buy a new 4 channel amp and I don't want to under/over(blow) power any of my component speakers....

definitely leave the amp in 4 channel mode and run fronts/rears with it.
infinity refs aren't very forgiving when overpowered and tend to blow. you'll also get better results with power to those alpines.
leave it powering all 4.

Thanks Glasswolf.....

So I should just chuck the Orion amp and not use it for these speaker?
