I plan to wire up a 800 Watt Amp to my car, but Ive heard so many things about the Brain and all this other stuff that could possibly go wrong with my car if I do indeed install it. Are there any extra precautions I should take when installing this Amp. Ive installed a amp in my 94 Honda civic. And it was fine. But this car is my baby I would not like to ruin the brain in this fine car. Let alone the Electrical system.
