My first question

[edouble 0]

Whats up all! I am about to purchase build new system and I am starting with the low end. I want great sound quality, reliability and lots of output!

Big 3 (Optima 750CCA and factory 90amp alternator)

Alpine CDA-9887

Alumapro Cap5 V2

I dont know which amp yet but I have it narrowed down to these two choices

Sundown SAZ-1500D

US Amps 400DE

I think I am going with one 15" subwoofer and I have narrowed it down to these three choices

RE SX15

Fi BTL 15

SSA XCON 15D2

What amp and sub combo do you think would be best? All three subs seem great and both amps are excellent, any advice?

Welcome to SSA. I would suggest reposting your question in the General Audio section. You have 3 very different sub woofers listed, so we need to figure out which is the best route to take based upon your goals.
