What kind of amp specs should i look for? i have 2 15 inch subs with dual 4 ohm coils?
I currently have 2 alpine 15 inch subs that have dual 4 ohm voice coils. They are rated at 750w rms and 2000w peak. I'm looking to wire the subs to 4 ohms and need to find a sub that will provide the power to both. I've taken a look at a bunch but I can't seem to find one with enough rms at 4 ohms. Any advice for how to look.

Dual 4 ohm coil subs can be wired one of three ways.
All in series for a total of 16 ohms.
In a series/parallel configuration for 4 ohms.
All in parallel for a total of 1 ohm.
Your options to sufficient power will be much larger if you run them all in parallel. Finding an amp that puts out 1,500 watts RMS @ 1 ohm is a lot cheaper and easier than finding one that puts out 1,500 watts @ 4 ohms.

Sure, that amplifier shall be nice. It's rated for 400 watts RMS, and if you are now not familiar with the subs, then you definitely must stick to 400 watts RMS. The other alternative that you have is to re-wire the subs throughout the enclosure so the impedance of the field is shrink, after which appear into a mono-block type D amp.
