Is this possible?

[tee 10+ year member]

First off, I am completely clueless when it comes to sub wiring.

Is it possible to wire (two) Dual 4 ohm subs to 2 channels (bridged) on an Alpine MRP-F450 amp?

The subs are 175 RMS and the amp is 4x70; 2x200 RMS @4.

Thanks.

If your amp isn't 2 ohm stable in bridged mode, you can do it, but you'll have to wire the subs as 8ohm each

Wire each sub in series(8ohm) then parellel the two together to get 4ohms ran to your amp bridged.Or wire each speaker in parellel(2ohm) and run one channel to each speaker not bridged.

I believe it's a 4 channel amp, so that wouldn't work?

Yes, it is a 4 channel amp. 70x4, 200x2 @ 4 ohm. I guess it won't work then?

You'll need (2) D2 or SVC4 to achieve a stereo 4 ohm load.

oops...I seen the 200x2.Should've read it a little better.

A 4ohm voice coil into each of the 4 channels, or just 8ohm bridged x2 like budget76 already mentioned (functionally equivalent, so it's up to your preference). Those are your best options with that equipment. It is too bad, but there you are.

You still end up with 140w/ sub, so not too bad.
