right on…

you have to be careful with ohm loads too. most home stuff is 8ohms. most car stuff is 4. pending on the sub it might be a dual 4 ohm voice coil. if it is your in good shape just run it series to get 8 ohms.

I am not real sure where you would pick up a home style amp to power that bitch?
