I've been looking at my amp certificate and I noticed that it will put out a little more power at 2ohms. It's a Rockford 450.4 bridged to two 10" Rockford P2's. The subs are SVC 4ohms. By the book I'm putting 225W to each sub, but I'm pretty sure the amp is putting out a little bit more than that. I know that you change impedance with wiring, but I don't know what to switch around. Can I drop it down to 2ohms for more power or will it not work with my equipment? Or does impedence matter anyway when you have an amp bridged? I was just wondering because more power is always a good thing.

 

I would imagine the amp is 2 ohm stereo stable...as in you can run 4 2 ohm speakers... You really cant do much with the amp and sub combo you have.

 

Two run the amp at a 2ohm load then you are going to have to wire your speakers up differently. Take your wiring from your subs and run the two positives together and the negative also, and then run one positive and negative to your amp. You will have to look in your manual that came with the amp and see what channels you need to use on the amp and you will be good to go.

 

I tried wiring up my subs that way not to long ago. It sounded good, but it threw my amp into protect mode way too much. I guess I can't do this with my equipment. Well thanks anyway guys.

 

If the amp went into protection mode than the amp is not 2 ohm stable. I would just run the amp at 4 ohms, unless you want to buy another amp.
