im interested in creating a custom install
firstly a couple questions
i have a audiobahn a8000t and twin 10" 100 watt subs
i am also going to put in a power cap
i was going to install this on just the standard battary
but i have seen a lot of people are using these yellow top battarys
and as i like to listen to music in the car without the enginge running they
claim that they can maintain the sound system with no drop in performance for 120mins
the question i want to know is how does it work?
as when you turn the engine off how does it not drain the main battary do you have to remove something for it not to drain the main battary?
and how is it connected to the system?
do you need to connect both sides of the battary to the yellow top one?
has anyone used these?
if so any comments or problems to look out for?
any aditional advise
