how should i run my grounds

[Ununpentium 10+ year member]

ive got 2 amps, both PPI's

1) PPI PCX 4125 ... 1000W 100A max draw

2) PPI PCX 2400 ... 1600W 160A max draw

ive been to quite a few moblie audio shops and some of them said that these amps can be grounded right in the trunk with the 4 gauge ground wires comming out of the amp, and others said you should run all of the 4 gauge ground wires into a distribution block and back out of the block with a 1/0 running back to the battery.

who is right?

doesnt it go by how big the system is that you would ground it using one of these methods?

thanx for the help!//content.invisioncic.com/y282845/emoticons/up2something.gif.dd110ecf3ae4b76050d87598f2f8de7c.gif

It might work fine with it grounded in the trunk. It might turn out to be a bad grounding point for that amount of power. You can install it and find out or you can go ahead and make sure that everthing is good and ground back to the battery the first time.

I'm curious on this issue aswell.

How about try a search? There have been at least 3 threads talking about grounding back to the battery this week.

I run multiple amps and have 4ga ground running from the amps to a distribution block, and a short length (about 2 ft) of 1/0ga running from the block to a spot under my rear seat, using a nice Stinger grounding plate. No problems.

x2. "common ground" is the best bet. shouldn't have any problems tho.

I'm planning on using a 1/0 Cable for my main ground to the trunk. Using a streetwires grounding block(looks like a triangle with 3 screwholes) From that the 1/0 wire is going into a Stinger HPM Distribution block where everything will tie into. It has connections for 4ga and 8ga cables.

Gonna do this for my grounds

Car -> Dielectric Grease -> Streetwires Ground Block -> Dielectric Grease -> Streetwires 1/0 Cable -> Dielectric Grease -> Stringer HPM Distribution Block -> AMPs/Computer/Whatnot

For my Power i have a stingpro digital ANL fuse holder thats going in the engine bay. From there i go 1/0 to the trunk to a Stinger Midi/Mini ANL digital fused distribution block (Eventually. for now I'm going to use a knukoncepz mini fuse block since the Stinger is roughly $100)

I'm thinking about putting a Circuit Breaker in the engine bay. Not so much for protection. More for an easy way to cut power to the entire system.
