The Camaro has a 70ah battery.
I use a ctek charger that has an 8 step charging program and is rated at 4.3 amps charging power and has a capacity of 110ah.
Maybe you just need a bigger charger and you must track down any parasitic drain from accessories etc.

Any charger no matter how small would be more than powerful enough to overcome any kind of small draw from any electronics. You do not want to do a full blown charge on a battery that is sitting, that too will kill it.
