So I really dont want to deal with upgrading my alternator and if I could avoid having to upgrade the big 3 (although it doesnt seem too difficult) that would be great. Anyways I just want to add some subs (perhaps dual 8s or 10s or perhaps a single 12, maybe even 2) but I really dont want my lights to dim.

What would you guys say is the biggest system that the stock electronic parts could handle?

 

I've got 2 12's and my stock alt has been doing fine, but IIRC I've only got a 300 - 350w amp pushing them. Still sounds great.

 

I ran a 1,027w RMS (amp dyno proven) amp along with a 200w deck on the stock battery, alternator, and wiring. If I had the system up loud at idle it would dim the lights. The dimming was pretty minor so I think if I upgraded the alt to battery positive, and the battery to chassis ground I would have eliminated most of it.

 

I have a ~4x100W RMS amp for the speakers and a 500W RMS sub amp on my tib. I rarely have them turned all the way up, but I have had no problems.
I have a couple of 8AWG wires in parallel with the stock battery negative wire, and a 4AWG wire going to the amps.

I wouldn't go more than 1000W RMS total. Stock alternator won't put out more than that.

 

Im running 2 15 inch Lanzar max pros in a sealed box with a bridged 2000 watt amp and it hits super hard.
head deck is a kenwood.

my lights do not dim.
my battery is a interstate battery.
The only thing i worry about with my system is breaking my back window.

 

In my 01 Tib, I got 2 15" iPipe Subs w/ a 1500.1D Audiopipe amp, 4 Gauge wire (havent done the big 3), xtra audio battery in the trunk, and a Kenwood Headunit



the deck limit is 36, cranked to 25 at night the lights will start dimming (even w/ the xtra batt)

i need to upgrade the big 3 tho :S
