read around the forum and learn a little more imo before you try to tackle a whole build with 0 knowledge at all.

many people here can design you a box if you wanan go that route, and there are many many amps you can choose to achieve what you want.

Id sell the d5 subs and get 2 more d2 subs so you have a final 1ohm load. and look for an amp that does about 2krms at 1ohm. dont place over rms on subwoofers when you clearly dont know what you are doing. Thats horrible advise to give anyone whos just starting out.

also nobody knows what vehicle you have so to tell you where to put a port without that information is idiotic at best

I have a 02 chevy suburban the long one, like steves!

I'm not sure how big the port hole should be
