Max amount of power on electrical before upgrade?

lol what did u bass race with it i did a 141.9 with mine on 4ga then after i did second batt and 1/0 i could do 145.5
it was a 140.1 i think. but that was in a trunk firing into the trunk. i turned it around and sealed it off since then

 
Never hurts to try things and if it's not enuff upgrade from there.

I would do at least

big 3

couple runs of 0/1 gauge

2 new batts, one under hood and another in back.

If this isn't sufficent, time for new alt.

 
if you get a fairly efficent amp and put at least 2k-3k cranks amps of bat in the trunk you should be fine with a 120amp alty. I run my kx 2500.1 + car off a single d3100 with no problems staying around 12.5v full tilt, stock 120amp alt.

1/0, good grounds, and big 3 are a must.

 
I have an '04 dodge ram 1500 4.7v8. I want to run around 2500W, and I was told I am going to need a HO alt, and an extra battery. I was planning on just doing the big 3. Will I be okay? Whats the max you can run on stock electrical? Not sure how many amps my alt puts out though
I asked the same question a while back on dodgetalk.com forums. there were a few people running over 2000 w/o HO alternators. where are you putting your sub(s)? I'm getting ready to build a fiberglass box for under the back seat of my 03 QC.

 
Ah okay. I want to put it in a custom box behind the seats. Previously I took out the middle seat and but the box there but its kinda dumb looking
