I have a RF t3002 that does 850RMS at 2 ohms bridged. I was wondering if I got 2 12" subs that are D4 ohms, could I somehow wire them to get a 2 ohm load? I know 1 D4 sub could get a 2 ohm load but could 2 D4 do the same?
You're asking a simple mathematical problem. Whenever you wire 2 resistance in parallel, it cuts in half. Therefore, 2 dual 4ohms will give you 1 ohm when it's done. Either get 2 D2 ohm subs or get 4 D4 subs.
