Crunch gp3000d-pro, high output alternator and second batteryFIRST OF ALL... What amp are you using to power these.. the sub is the least of your worries, when you are thinking about pushing that much wattage you better make sure that your alternator can take it and think about getting another battery also! If you do not have an amp that can push 3000 wrms consistently forget about it!
well shithead...does it?Fegget.
To give you an honest answer, try to find a nice Solo X 12" on ebay. Should take the GP pro nicely.
