Pulling out 8 gauge wire for bigger cable; necessary?

[wey]

A few years back I had 8 gauge wire ran from my battery (with an inline fuse close by) through my firewall back to my trunk where the goods are. I have the + 8 gauge wire ran straight to a capacitor, and from the capacator there are two 8 gauge wires ran to (a) HiFonics 1000.d amp for 4ohm sub and (b) Kenwood 130 watt amp for my 6x9.

There is NEVER heat issues even when the volume is cranked for a period of 2+ hours. My lights barely dim even.

(Pontiac G6)

NOW...

I want to upgrade my HiFonics amp to something double that power. Would I be able to add an extra battery in the trunk and directly wire the + to that battery, then have the capacitor comming off that battery going to both amps WITHOUT having to upgrade the thickness of the 8 gauge? REALISTICALLY SPEAKING

Ditch the capacitor. What are you planning on running? 8 gauge should probably be replaced anyway, even if you don't upgrade

8 gauge is too small, could prob only just get away with 4 gauge, i'd suggest you do it once and just run 0 gauge

toss the cap. run 0g once so you will never have to worry about it again, and add another battery in the back... also do the big 3 upgrade if you havent yet

Before you change anything else, replace the 8 gauge with 1/0 and then tell me that wire size doesn't make a difference. ;-)

That would be redundant if he runs 1/0ga back to a battery, he could just hook into the battery terminals.

OP, ditch the 8ga and sell the cap, get 1/0ga, do the Big 3, and enjoy.

I had one of the HF 1000.1 D it calls for min 4 ga wire regardless. If you had larger wire you could have saved loot by not buying Cap. My advice use the 8 to pull either a string or the new wire in.
