i was looking at getting this sub
and running it with this amp
but if i add a second amp later for speakers, i've been told i'll kill the battery in my 1990 TX5.
A guy i know said he can install a second battery in the boot, which would run the system.
just wanted to check with some people who know what they're talkin about to see if this idea is ok, and if it will cause any problems etc.
the only details i know is that the battery would be in the boot, and that he said something about a switch inside the car that lets u choose which battery is charging....
thanks in advance
