How to wire batcap 2000?

[ghart999 10+ year member]

Adding a batcap 2000 as 2nd batt along with red Top as main.

The batcap.net diagrams confuse me.

Can I not ground the batcap to the chassis? I have to go direct to main batt or amp?

I mean how can one fit two 0 gauge ground wires into the amp?

Also what about power? Can't I go from main bat to batcap to amp?

I would think I could just do the following:

Power from main bat to batcap (fused near batcap) to amp (fused again).

For ground, can't I ground the amp and batcap at a common ground point on the chasis?

run a power from your underhood battery to the batcap, ground the batcap to the frame, and ground the amp to the batcap

if you're grounding to chassis/frame, make sure its a nice, clean ground. no paint or anything, otherwise you could have problems

Thanks a lot.

Can I ground the batcap to my ground distro block or use a separate ground?

Also what is the reason to ground the amp to batcap and not chassis/distro block?

you want the least amount of accessory grounds as possible. An ideal setup would be straight battery to battery ground, but you can get away with a frame/chassis ground if its a darn good ground. The best way for this would be to ground the battery to the frame, and ground anything else to the battery.

Makes sense. Thanks again.
