Hello, just looking for some advice on my build ill be working on.

Currently have 2 Orion HCCa152 Subs. I have the 2ohm ones at 2,500w RMS each.

I was wondering if anyone knew of any good amps that can run 5000 watts at 2ohms

THe biggest alt I can get is 270A and ill be buying from either Mechman or Singer.

And my second question is, how many batteries should I expect to run with this buiild, and which ones will be best?

I have a custom box built for my car. I have a 2010 forester. It'll be tuned to 28hz.

Would also like some recommendations on a mid/highs amp.
