Rockford Fosgate R300-4 Best Option

[r1addict]

Hi all, I have a question about how to best utilize the power available to me from this Fosgate 4/3/2 channel amp I purchased. Problem is I jumped before I looked and now own this amp that is, or appears to be, underpowered for my application.

Here are the wiring options for the amp:

50W x 4 @ 4 ohms
75W x 4 @ 2 ohms
150W x 2 @ 4 ohms bridged

Problem is that I want to run four, 75W (rms), 4 ohm, two-way speakers. I thought I could do it bridged with this amp untill I realized the obvious impedence problem with doing it that way.

So, what configuration will produce the best result from this amp? Or, can I still go the bridged route, with two speakers in parallel and a 2 ohm resistor in series with them? Or can I go with really small gauge cable and get the same affect?

Thanks so much in advance for any help or advice.
