guimond47 Posted January 14, 2011 Report Share Posted January 14, 2011 i have 3 type R's and my subs make the whole truck just dies out. my voltage gauge drops to 9 volts and its a brand new batt. im sucking like 200 amps. and my stock alternator cant keep up and its 90 am oem altornator. i was wondering if a 136 amp altornator would work. and ill add another batterie out back. let me know guys Quote Orion 2500D , 2-10" alpine type X.

Dan2427 Posted January 14, 2011 Report Share Posted January 14, 2011 I have same jeep and Im at .5 ohm with 4000+ watts with stock alt and 2 batteries in back and like 150ish feet of 0 guage and I dont drop below 13.7 if Im driving at idle I gotta be careful cuz I drop to 12s. But I'm buyin an alt next. I would just buy an alt and extra batt if I were you then u have room to upgrade.

Watch the bass Posted January 14, 2011 Report Share Posted January 14, 2011 Think a 200 amp up alt would be fine and a second batt at the amps. Have a look at Mechmanalternators, DC Power or something like this, another good place is the want to sale section in the forum.

Rebel4055 Posted January 14, 2011 Report Share Posted January 14, 2011 What amp do you have? Quote Rest In Peace mother. January 22, 1955 - February 14, 2013 http://www.stevemeadedesigns.com/board/user/35351-megrch/ Link to comment Share on other sites More sharing options...
guimond47 Posted January 14, 2011 Author Report Share Posted January 14, 2011 anyother cheap way of getting better power. like i herd that a durango 5.2l or any dodge 5.2L engine altornator can fit on my jeep 5.2L soo i was thinking of getting a big amp alternator at the junk yard from a 5.2L enigne...let me know if this can be a better alternative.

TeamHT Posted January 14, 2011 Report Share Posted January 14, 2011 Well....the sub or number of subs does not affect the current....your ohm load to the amp does. Turn the gains down, wire to a better ohm load pulling less current....have you done the big 3? This will help somewhat but I just don't see 1000 watts being such a huge draw. I can't say whether or not a durango alternator is a direct replacement, but can say if you're going to upgrade, upgrade right the first time and contact Mechman.

Rebel4055 Posted January 14, 2011 Report Share Posted January 14, 2011 Yeah I think there is other factors involved too. 1000w shouldn't be a problem on stock stuff. How did you gain the amp.

jeyrapboy Posted January 14, 2011 Report Share Posted January 14, 2011 I am running a little over 1k on my current stock 90 amp alt and am not having any voltage issues at all... Big 3 done and 1 run of 1/0 to the back Quote Link to comment Share on other sites More sharing options...
crunkjuice1 Posted January 14, 2011 Report Share Posted January 14, 2011 A high output alt is built from the inside out to handle more current overall and most companies like mechman have different amperage alternators to suit your needs. You don't necessarily need to buy their biggest one either. Quote Link to comment Share on other sites More sharing options...
guimond47 Posted January 17, 2011 Author Report Share Posted January 17, 2011 (edited) ill just try to get a red top batt out back and an 200 amp batt isolator between the front batt and the rear batt so i dont drain the front batt but yet charge the rear batt;) make sence:P?
