Not too many people are fans of caps around here - especially not for daily use.

I think that the consensus is that they are a waste of money because they do not work. Also, there is a school of thought that they are just another burden on your electrical system.

I think that even those who advocate them would say that they are not a cure for a less than adequate electrical system.

If you want some in depth reading, do a search for "Richard Clark" on here. You will find a thread that discussed caps at length.

yea i never used a cap in my life but my lights dim so much that i cant even play my music at night cause i look like a disco ball. i guess i need to add a 1/0 to my alt and engine block.

alright i read many of the pages in this thread, but still have some questions, so im going to be adding this wiring to my wires that is already there? so i would get a battery terminal where i can have multiple wires coming out of it one for my stock wiring and the second of the 0/1 gauge wiring for the big three?

you guys know wheres the chassis for the 06 Camry? I think its hidden way down below the engine, but i could be wrong

Was just wondering if it really makes sense to use anything larger than 6 gauge from B+ to alt when the brush wires inside the alternator are so tiny...

I am getting ready to upgrade my alternator to a high output alt and also do the big 3.

I have a few questions:

1. My factory wiring from the battery negative has 2 wires, 1 to the frame and 1 to the engine block. Should I upgrade both?

2. If I should upgrade both, is it still necessary to add a frame to engine block wire for the big 3?

3. The high output alt manufacturer recommends adding a new wire from the alt case (negative) to the frame. Is this necessary since I am already doing the big 3?

Thanks for any help.

add that but more then likely you will need to get a good bat or two bats.

Ok just gonna run down the (planned) setup of my car...someone feel free to point out an error or simply say no it wont be enough haha.

4g power wire to 800RMS sub amp split to 150rmsx2 speaker amp

4g for the big 3

2farad cap

ALT is rated 85-90amps

8g speaker wire and grounds for cap and both amps

will i truly be pulling what my amps are rated for or coming up way short?

ill prob put it in anyways but im sure an Optima yellow top will help, correct?

i had a question. OK for the big 3 can i use power wire also for ground.
