jabo6692 Posted July 6, 2012 Report Share Posted July 6, 2012 Hey everyone, so the stock alternator in my 1998 4runner 3.4L V6 is not doing it for my system. I think it only runs like 70 amps max.. My lights dim a lot when i turn my subs up and my amp sometimes cuts off and starts blinking a yellow light on heavy mid notes then turns back on when notes return to lows and highs. From what I read that means I'm running low on voltage and need a new alt. Therefore, I'm looking for advice as to what high output alternator i should go for, I will list my current system specs and if anyone could point me in the direction of a good H.O. alt for my car & system that would be awesome! My budget is anywhere up to $800. My system currently consists of: Head unit: -Alpine IDA-X305 Sub Woofer: -Kicker zx2500.1 with 1/0 gauge wiring from batt. & ground running at 2 ohms -25 farad capasitor -2 kicker L7 15's -4.7 cu ft custom box tuned at 25 hrtz Speakers: -Alpine PDX-F4 with 8 gauge wiring from batt & ground -Alpine Type R spr-17c & spr-17s speakers Battery: -Toyota True 2 (0554-035T2-525) I will be installing the Big 3 upgrade along with my new H.O. Alternator. Quote Link to comment Share on other sites More sharing options...

Fosgatefeind Posted July 6, 2012 Report Share Posted July 6, 2012 Excessive amp is very cheap too. Also I didn't see any one say it but get rid of the capacitor and get a battery or 2 in the back Quote Buildlog: http://www.stevemeadedesigns.com/board/topic/146515-2007-monte-carlo-ls-build-new-plans-with-dc-audio/ TEAM DC AUDIO www.Dcsoundlab.com Link to comment Share on other sites More sharing options...
Kranny Posted July 6, 2012 Report Share Posted July 6, 2012 biggest one you can get from mechman or dc power or something similar to them. why do you want to tune your box to 25hz? Quote Link to comment Share on other sites More sharing options...
HHR Ed Posted July 6, 2012 Report Share Posted July 6, 2012 Looks like I got a 220a for that truck for 5 beans. And yes, the largest you can get but it also depends on your batteries. The alt and batts work together. The more power you want, the more batts you need, the more batts you have, the larger the alt that you need.

HHR Ed Posted July 6, 2012 Report Share Posted July 6, 2012 What you should do, is run a nice AGM batt up front like an XS D1200 and a small supplemental in the back like a XP750. That will be good for 3500w systems. Or you can go to a XP950 or larger or add more later. But that setup, with the 220a alternator would run very nice with 0awg wire all around. And can be had for your budget of $800 Quote Ed Lester ShowtimeSPL Host Showtime Electronics Video MarketingMy old Build Loghttp://www.stevemead...08/#entry511451http://www.youtube.com/showtimespl 5 time dB Drag Finalist Last ride 2007 HHR, current dB 153.5 and bass race 149.4 dB. 153.0 dB on music New Ride, 2008 HHR SS.

jabo6692 Posted July 6, 2012 Author Report Share Posted July 6, 2012 (edited) So i ordered a 270 amp alt from DC power, so I've got plenty of room for power. Now how many batteries and what type do i need for that alternator? Also, is it necessary to add more batts if i'm only going to be running this system while the car is on?? [quote name=Kranny' timestamp='1341596021' post='2081668] biggest one you can get from mechman or dc power or something similar to them. why do you want to tune your box to 25hz? And to Kranny, the box was made by a friend according to kickers recommended spec's for these subs or something. I'm planning on building a new box tuned to 32 hrtz. Any recommendations as to how big i should build the box for the amount of watts I'm putting to the subs and the tuning? I was thinking about 8 cubic feet with 125 sq in. of port area. And that's inner chamber cubic footage including all port and sub displacement. Edited July 6, 2012 by jabo6692 Quote Link to comment Share on other sites More sharing options...
