I'm not really understanding the question? Or maybe I don't understand why you would want to do it?

People who have those "big" systems either have a big capacitor or a seperate battery, in most cases. If not your going to fry your alternator.

I got ya. You said radio..... not some "huge" system. Batteries are for starting the car and using accessories while the engine is off but key on. The alternator is what your vehicle and accessories run off of when the vehicle is running. Once the car is started, you could actually take the battery out and it wouldn't be needed. So if you have a system big enough that draws more current than your alternator can supply, then it will start to draw from the battery(s). In this scenario your alternator could burn up prematurely. Adding a second battery is only a band aid. You could even argue that the second battery could be even more of a strain on the alternator. Because if you are over drawing from the alternator, then the batteries are losing charge. Once your music dies down a little where it's not such a strain on the alternator, then now the alternator has to charge "2" batteries back up instead of just one. Also, capacitors do not supply power to your vehicle's charging system. They only supply instantaneous burst of current for bass notes to reproduce them properly. They are nothing like a battery! So the real solution for a high current drawing system is a bigger alternator.... plain and simple.

You are talking about the old Kenwoods..... like the 707. They do not make anything like that anymore. They had lots of problems with the ribbon cables in the face. I don't know of anyone making a "mask" faced radio. You can still find used 707's though.
