thats a big box! i think id like to keep this system kinda tame to what ive done before. so 47 hz is the sweet spot for these grand prixs?

In my GP 47 was the spot.. fully sound deadened.. (Which will change the RF) I would suggest anywhere from 42 to 47 if you're looking for a burp box.. if you want something musical, tune that bitch to something stupid like 19Hz, and break shit! These day's I'd rather rock a ground pounder that can play music that rocks 25hz than have my stuff tuned to 4x hz, and only make certain songs sound good...
