So I have some free time to experiment.

I have several car amplifiers and two SAS Bazooka Tubes (are incar bass speakers)in addition to a few sub-speakers at home.

I would like to connect the amp to one of the bazooka tubes but dont know how to get power to the amp. any recommendation on where to get a "inverter" (think thats what it is called) 110AC----> 12DC

I am pretty sure that I need min 2amp transformer/inverter? ohms law 220watt amp/110volts=2amps correct?

thanks for any advice.
