If you asking about an idmax then 1, you said you wanna keep it under 1500w and that is the only way. I dont know if youve heard one but they can get low loud and sound badass while doing it. They are more of a sq sub but like i said still can get loud. Also the kicker wire is a good choice, you can get it on ebay for $80 shipped if you shop arround1....2....how many?
New and authorized would be $1000 unless you got a deal, now used or ebay or from this fs on this forum, $500 maybe a little over little underwhat would two IDMAX 12's cost
