What are some good subs (single) that are in the $200-$300 range like the RE SX 15" (on ebay) This will be my first sub and basically all im looking for is that its loud and can play reasonably well (pitch or sq w/e). But looking to spend around $600 for amp and sub, and i want to make my own box (if anyone has plans for ported). Im also wondering how to tune the box... I like the SX but i dont know theres probably others that are just as good that i dont know about... its just in all the SX videos on youtube it looks like its banging Alot..
