Need Help Bridging Amp

[Remo Valentine 10+ year member]

Sorry to bother you guys with this simple question, but I'm really struggling with it, even after doing much searching on my own...

I've got an Alpine PDX 4.150....it says it does rated power at 4 ohms and 2 ohms (150 wrms x 4)...it also says it does 300 wrms x 2 at 4 ohms...

I'm using the front two channels for my component sets, I want to bridge the rear two channels for a single subwoofer...

I need to know what load to present to the amp and what kind of subwoofer to buy...

Could someone please take a second to explain to me how to individually wire a single 4 ohm subwoofer, a dual 2 ohm, and a dual 4 ohm woofer. Also please tell me what would be ideal.

Once I understand what I can possibly wire, I can go ahead an order my subwoofer. Thanks!

For a single sub you're looking for an svc 4 or dvc 2 - the dvc 2 can be wired in series for 4 ohms. That will get the most power from your amp (300w) while keeping it within its intended load.
