Big 3 upgrade question

[sbelew 10+ year member]

Getting ready to do the Big 3 upgrade and a new battery on my '98 Cavalier. I'm going to use the Knukonceptz 1/0 Kolossus Fleks Cable and rings. I was considering running the battery to chassis ground to the left strut tower, and the engine to chassis ground from the A/C bracket to the right strut tower. But it seems I read somewhere that it is not recommended to have multiple grounding points? Is this true? and if so, should I run both the ground wires to the same strut tower?

If it matters, the alternator seems to be a 105 amp, currently looks to be 8 or 10 gauge wire connected to the alternator. I have a JBL GTO 5355 5 channel amp, running 4 speakers at 4 ohms and 2 8" subs at 2 ohms. It is wired with 4 gauge power and ground wires. According to the amp ratings, I have about 580 watts of power.

The Big 3 will not hurt to do but is not very necessary for that power level.

Running the grounds from the motor and battery to different spots will not cause a problem.

Typically it is grounding equipment in different spots that can cause a problem (although I have used different grounds b4 without a problem)

You should run a wire from the Alt + to the battery + as well.

and it is recommended to fuse the alt to batt +, to protect the battery. fuse at the battery.

Yea, I was going to do that, just trying to find a reasonably priced waterproof fuse holder.

You're running a pair of 8's and a single 12?

 

[sbelew 10+ year member]

The 12 is in the truck, the two 8's are in the car

Sorry man, I read from the bottom up and stopped at subs haha. I would realized that if I was reading it properly, my bad.
