Well, I tried searching for "big three" and the server is being RIDICULOUS and returning no hits. So I'll ask:

I'm currently running an Alpine PDX2.150 amp and a PDX1.600 amp that totals 900wrms for my system. Both are fed by a single 4AWG cable split into two other 4AWG's via distro block. Now here's the Q: Do I need Big 3? Or would you at least advise it?

Also, what do you gain from it besides better grounding, since the search is effed?

Thanks in advance.

 

the big 3 wouldn't hurt but i don't think it's needed.

 

a capacitor would help, big 3 can help if u test it... turn on ur dome lights and knock ur system. if the lights dim then try using the big 3, capacitor thing.

 

I heard caps were a waste of time...ineffective? Is there any proof of their benefit?

 

yeah, if u hook em up to ur headlights to prevent dimming

to the OP, here's some good reading... https://www.scionlife.com/forums/viewtopic.php?t=192160

 

just try it w/o doing anything and see. i think you'll be suprised that you'll get no dimming at all.

 

yea ive never been a big fan of caps so got one of those kinetic car audio batteries instead of a cap.

 

i think you'll be pleasantly surprised that it won't take much power to get that sub loud anyway. you should be fine with those 2 amps.

 

I am running the PDX4.150 and PDX1.1000 with a ps2, headrest monitors, flip out dvd, underbody, strobes and interior lighting and have no problems with my alternator.

 

Oh damn, I should be fine then lol... BOX JUST GOT HERE! :D

 

Sweet, post some pics when you get it all in.
