MOUZEBINN Posted December 6, 2009 Report Share Posted December 6, 2009 I have a 97 Grand Prix SE 3.8 V6 250HP it's all stock.. I believe my alt. is a 105AMP right now im running a 600RMS MRP from alpine and I get decent light dimming, I was looking online I can get a 220AMP alt for my but it's going to set me back $300 (last resort guys..) im wondering if my car will handle upto 1500WATTS im going to be running two Fi 15" SSD's @ 750RMS each (running the BP power addon and copper coil.) Is my 105AMP big enough for that or what?? whats the cheapest upgrade next to the alt. to get running 1500WATTS stable daily? Also, my seat doesnt fold down, im not about to take it out because I LIKE having a car for the reason I can have 4-5 people in it... I was looking seats will cost $100+ and thats if I can find one in my area (looking like false hope) I was going to cute 4 holes in my back speaker panel (between my 6x9's) and insert these babies: http://www.amazon.com/Parts-Express-Port-T...9875&sr=1-4 I figure that will give me about 24" around port in my rear... that should be the equivalent of putting my seat down or at LEAST having an armrest that folds down... Now my only concern is that the port will be facing upwards towards my window, so should I face my subs upwards or towards the trunk like I am already doing?? thanks everyone for your help Quote Current Setup (pictures/videos uploaded) 1997 Grand Prix Se 3.8 V6 (220HP stock) 105A Alternator Big III 5/8 Gauge Wiring 1 x Alpine MRP-450.1 (1x450RMS @ 2OHM) 1 x Alpine MRP-500.2 (2x250RMS @ 4OHM) 2 x 6 1/2 Infinity Reference 3-WAY (250RMS) 2 x 6 by 9 Infinity Reference 3-WAY (300RMS) 1 x Pioneer dEH-11 1 x 3.5cu .75MDF tuned @ 33hz (VENTED) 2 x Kicker COMP 15" S4 Coming Soon!

MOUZEBINN Posted December 6, 2009 Author Report Share Posted December 6, 2009 (edited) just get a decent front battery and a deep cycle in the rear. Sorry for my newbieness whats a deep cycle?? and how much does a good battery run? heh, im not mechanically inclined on auto part pricing... link me to a good battery that wont cost as much as a new alternator lol also any thoughts on my port design for my rear? it'll be pretty much like having a hatcback with removable rear support also.. batteries are like $150 for a HO one... and a deep cycle is upwards of $100... thats $250 i mights as well get the 220AMP alternator at that price... theres really no way my car can run 1500RMS with a 105AMP alt?

Bumpindemlowzz Posted December 6, 2009 Report Share Posted December 6, 2009 (edited) walmart sells everstart deep cycles they are about 100 bucks with tax and a decent front battery is the same price. For a rear battery you want more reserve capacity not so much cranking amps sense thats what the front battery is for. I dont think you need to upgrade your alternator yet... You have to be able to make the power and you have to have someplace to store the power. Your cars electrical isnt a thing you want to skimp on. i ran 2000 watts with a stock 105 amp alt and it was fine all i did was what im telling you now. Yes it would be nice to get a ho alt and the two batts im telling you about.

Bumpindemlowzz Posted December 6, 2009 Report Share Posted December 6, 2009 Do you know how to wire up a rear battery? Just run pos from front batt to rear batt and ground the rear batt to chassis. Make sure to fuse inbetween the batteries and the rear batt to amp-amps. Quote 2010 Silverado 18" DC XL 18 DC 2k XS Power Batts Link to comment Share on other sites More sharing options...

Make sure to fuse inbetween the batteries and the rear batt to amp-amps. So I can just run my current battery, grab another battery throw it in my trunk, wire it up (yes i know how to) then put the deep cycle in the back as well?? or is the deep cycle the 2nd battery? im not really sure what deep cycle is... how much would the big 3 help also? i have like 10ft of 0/1 gauge lying around I could do it with.
