And re: secondary battery. Di ba di naman sya gagana when the engine is off? So how can it prolong playing the stereo while it is off? Or was I misinformed by our company electrician?
Who connects your stereo system?

Your system must connect on the ACC in your early ignition switch on the ACCessory terminal. If your stereo is not working on the ACC switch position when your engine is off then have an car electrical tech. to correct the problem.

Acc is an early ignition that has a ACCessory terminal. The early switch wires were only IGNITION, BATTERY, START. One big reasons to have an ACC terminal was that you put your STEREO on that terminal so that when it was ON it get full battery voltage. The ACC terminal was hot in the IGNITION position as it was switched off in the start position, giving the ACC 12 Volts or 14 Volts.

What is your estimated electrical current that your system draw?
Go back in my previous post how to estimate your current draw and estimate your system current demands.
