Yeah bud, glad we could help. good luck with it and i hope to see the build in the future! Thanks its my winter project since the car is going into storage! Will be ordering the 15s very soon! Any input on amps?? I would rather run 1 amp, playing @ 1 ohm if possible to both fo these subs. personally i have been jaded by Sundown Audio. I highly recomend the amps, and if you have the money go for it, they are well worth it. You could do an SAZ-3000D to 2 dual 4ohm subs that amp will give you quite a bit of power and will make the mayhems sound great. you could also even go for the SAZ-3500D or 4500D. Im not sure what kind of elec, system you have but i would say go for the Sundown SAZ-3500D. that would give you plenty of power to make the mayhems hump it.
