so 95a alt 650a bat, using 1500d sundown amp with 18" Fi Bl. Do i need to do big3 or can I survive without it?

I would do it no matter what!!

I don't have a system right now, and I am doing it in the new truck. I gained .3 volts in the old truck when I did it.

k but im pretty sure im going to mess up :S first car. so follow instructions, leave stock wires on and ill be fine hopefully.

I changed all stock charging wiring.

Alt +/-

Batt +/-

I grounded engine to chassis

All in 1/0

Not to thread jack or anything...... but...............

How do I make an animated avatar? Like the one the guy above me has?

I would definately do it..i gained a little over half a volt. I have a 15" SSD at 1000rms and i never drop below 14 volts because of it.
