Big 3??
I've been wanting to do the big 3 ever since I realized that my 2.0 farad cap isnt enough for my 1000 watt amp at loud volumes (lights dim).
Just out of curiosity, How many of you guys have done the big 3 for your audio system? Has it made a noticeable difference? Please provide pics if you have. Just want to get an idea on how I should run the wire from the alt to the batt. Thanks |
i have.. running 1600ish rms to the subs, 500ish rms to the speakers.. with just a bettery upgrade and big 3, no dimming
cap is a waste of money imo.. as for running the wire, just run it however you can that will make it look stealthy (thats if u're anal about seeing the wire), and away from anything that may become hot |

What kind of battery are you running?
|
Whats the big 3? I'm guessing battery, alternator, ???
My boss also told me something people forget is to upgrade the ground wire going from the negative battery post to the chassis. Is that going to help at all? I thought it would since usually that wire is usually pretty small and looks corroded like hell. |
Battery negative to chassis
Alternator Positive to Battery Positive Alternator ground to chassis Big 3 and I'm running a Optima Yellow top D51 (Biggest yellow top that can fit a tsx) |
If u already have the yellow top, def do the big 3. I plan to do mine this winter, I have all the wires sitting in my garage
|
how many feet of say 1 guage wiring would you need for the big 3?
|
depends how big your engine bay is, and how you want to run your wires?
Take some string and run it, cut it, measure it, and add an extra foot or so, since the wire isn't as flexible as the string. You might want to consider kicker hyperflex and/or knukonceptz kollosus fleks for your choice of wiring.. High strand count + flexible + looks good :) |
1 guage is a bit ridiculous, you don't need more than 4 guage, I used a measuring tape to figure out how long I needed, and bought extra :biggrin:
|
I use to have 1/0 wire in my car, it was about the most grossly unneeded thing ever. But it was cool to see.
|
Stock wire is like a 6ga.. smaller than 4ga but bigger than 8ga.
If you're gonna do the big 3, do it with at least 2ga or 0ga; sinec you're going through the trouble with doing it anyway.. just my :2cents: |
my stock wires are like 8 guage
|
What amp are you running and how efficient is it? I didn't think that the amp draw off 1000 watts is enough to dim lights..
|
Im running an alpine MRP-M1000 and MRP-350. It only dims if I have it at loud vols and it dims even more if I have the A/C on but its not super bad. The the 1000 watt amp should be efficient, its a mono class D amp.

Don't mess with the stock stuff. Just add to the stock wiring.
+1 on the Kicker Hyperflex. They make the best 1/0 wire I've ever seen, period. |
^+1
Electricity takes the path of least resistance; doesn't hurt to have more than 1 route for it :D |
i looked at my car (02tl-s) and i saw that one wire from the alternator goes to what looks be like to the engine and it grounds their and the other wire goes to a fuse box, anyone got any pics on how hey did they alternator set up?

sorry I'm learning so bear with me, do you add another ground from the batt. - to the chassis, or upgrade to a thicker gauge than stock? Then upgrade the alt + to batt + wire? and then add another ground for the alternator? just wanna be sure, thanks

Battery negative to chassis
Alternator Positive to Battery Positive Alternator ground to chassis i ordered 10feet of 1/0 wire should be enough. |
Oh yeah, sorry I should've mentioned this earlier, get a fuse holder unless you want to risk shorting out the wire and potentially causing ur car to burn down!
Amp size to the wire 0ga - 300amp 4ga - 150amp |

what about a 1ga?
|
this is what i did, i had some 0ga lying around, so i used that as well as some 4ga.
0ga from alt to chasis 0ga from battery to eng block 0ga from battery to chasis 4ga from throttle to battery 4ga from manifold to battery i went a bit over board, but i dont have dimming and i did notice my car to have better starting up, better throttle response, and all around better elctrical flow. if you still have dimming than unfortunately you may have to up the alt. or deal with it. |
