Where's the best place to ground your syetem?

[BradlyLovesSpl]

If anyone would fill me out on a full explanation! i would love it!

to the chassis of the vehicles

The chassis has the most negative current. All you have to do is clean the surface and get rid of and paint that is there =) Hopefully someone can give a full explanation

Drill a hole in the frame, sand it down to bare shiny metal, attach ring terminal to frame through said hole with bolt and tighten..

The best place is the neg on you batt

Neg on a battery is good, Only if the negative on the battery is grounded to your frame or chassis with good wire preferably 1/0 gauge. Personally I ground my amp to my rear battery since its like a 2 foot run from amp to battery and thats grounded to the front battery which is grounded to my frame which I sanded, drilled and tapped. Very solid connection to the frame. If you dont have a tapset a nut and bolt will work as long as you sand it down to bare metal.

Would a motor-mount bolt to the chassis be a good place to ground the battery? I do rear batt neg to front batt neg, front batt neg to motor mount bolt.

also for all vehicles that don't have frames (unibodies) I always trust stock ground locations. good thing about them is theres already a bolt there and you know it works.

Make sure you ground to the FRAME of the car. Too many people make the mistake of grounding to a piece of sheet metal. A good ground is VERY important to a good electrical. IMHO, you're only as good as your electrical. I upgraded my electrical before I bought my amp or subs.

What about the seat bolt? Would that work?

[skittlesRgood]

the alt charges the battery and the wire really only needs to be able to handle the output of the alt. if you ground the amps to the battery there is no current from the amp that goes through the chassis so you dont NEED more wire from battery to chassis. if you ground the amp to the chassis then you need to upgrade the battery ground because all the amp's current needs to go through that wire.

remember that DC flows from - to +. that ground is just as important as the power wire.
