TRTC360 Posted July 4, 2012 Report Share Posted July 4, 2012 yeah i'd stick to the 1500's until you can upgrade electrical, my guess is you're looking at drop to 10-11v if you were to run the 4500 at 1 ohm on your current electrical, i'd look into a 250amp+ alt and 3 XP3000's if you can fit them. My friends mazda 626 with a Excessive amperage 225amp, batcap 4k, and kinetik hc2000 was dropping to high 12's revved up on an RD3250.1 at 1 ohm and we still never maxxed the gain to it's highest clean signal.

zack_e89 Posted July 4, 2012 Report Share Posted July 4, 2012 Yeah I think I'm going to stick with two 1500's strapped if I decide to upgrade. Doing the math for a 4500, at 13v I would need 549.45AH's, even with my 220 alt I would need around 362.45 AH in battery reserve. Strapping two 1500's at 13v will only require 384.6AH my alt will bring that number down to 195, and a bt 120 and 2 BT-20's will be nearly a perfect match. Electrical is a bitch aint it.....

Thank's for the input, there is NO more room except in the bay to upgrade batteries. And upgrading the front batter will force me to remove the BT-35 in front. I plan to keep my 5 seater car a 5 seater. If I didnt then for sure 4 xs 3100's in the back Quote Scion tC SQ BuildiPad mini, lots of fabrication, daily drivenFord Explorer C Pillar Wall Build Just a cheap car to destroy with bass Link to comment Share on other sites More sharing options...

Electrical is a bitch aint it..... +1 and it doesnt help that batteries rate their cranking amps. I dont get how a bt-20 does 850 cranking amps? 20AHx14.4=288watts...so idk where 850 come from Quote Scion tC SQ BuildiPad mini, lots of fabrication, daily drivenFord Explorer C Pillar Wall Build Just a cheap car to destroy with bass Link to comment Share on other sites More sharing options...
