How do I hook up an amp?

How do I hook up my car sub and amp in my house?

• I have a car cd player, car amp, and 15" sub I would like to hook up in my home. If needed I can use my home stereo system but i still need my amp to push the sub. Does anyone have any ideas on what I could do? What I had in mind is likely a bad idea but I'm going to state it anyway to find out for sure. I was thinking maybe hook up a car battery to a battery charger and then running a power wire to my stereo and to my amp and then running the ground from the amp to the battery and hooking up everything else normally from the cd player to amp. Bad idea???? Kinda sounds it.... Let me know. LOL. Thanks! The party will likely be outside though...just for the record.

  Believe it or not I have done it. You need to make sure the battery charger has at least a 50 amp charge capability and use the biggest battery possible. Hook up the amp straight to the battery and hook up the charger just like you would any other time. Run RCA's from the variable output on the Receiver (usually has jumpers that lead back into the amp on the back. If it doesn't just use the tape outputs on the back of the receiver. But you will have to adjust the amp output with the gain control on the amp. Be careful and you won't fry anything.
