412 CVX Posted March 20, 2011 Report Share Posted March 20, 2011 hey everyone. I've got a 2001 mercury sable LS premium. it's a 3.0L V6 and it says something like 24 valve DOHC if that helps. basically it's a taurus with a mercury logo on it. i've been trying to find what the stock alternator's output is and i can't seem to find any definitive results. i'm seeing OEM replacements that say they're 110 amps but i don't know if that's a reliable number. so with that being said, i've heard rumors that if you wanna run two batteries, you will need a HO alternator because it puts too much stress on the stock alt. i'm going to be running a zx2500.1 at 2 ohms soon and my HU is already shutting off (i assume it's due to voltage drop) on me when i'm running it at 4 ohms and turn it up a little too much. right now everyting under my hood is stock but i plan on doing the big 3 soon. if i add a second battery it will likely be an xs power d1200 (unless anyone has a better suggestion) and i will run my system on that. so is this rumor true, false, plausible, confirmed or busted?

CaptainzPlanetz Posted March 20, 2011 Report Share Posted March 20, 2011 It only takes 5-10 amps to maintain a battery's charge, however if you are gonna be demoing all day it could be hard on you stock alt since you are running a 2500rms amp, so if it runs you XS battery down low, it can stress the alt since it has to bring the battery back to full charge, you shouldnt need a HO alt if you only plan on demoing for minutes at a time, but IMO you should look into a bit larger battery, I used to have a Kinetik HC2000 with about 1200rms and I never dropped below 14 volts with a stock 110amp alt, but in your case I would save up for a D3100 as it will feed the zx.2500 well, and leave you some room to upgrade later.

412 CVX Posted March 20, 2011 Author Report Share Posted March 20, 2011 it's more of a daily driver. i listen to it when i'm driving places so it's usually not on full force for more than 30 minutes at a time. but in the event that i do have it on for a couple hours at a time while driving in the city would the d1200 not be substantial for my setup?

matt402 Posted March 20, 2011 Report Share Posted March 20, 2011 id replace ur batt under the hood & at least the d1200 in back also. make sure to have multiple runs of wire front to back & also ground the back batt separately... . Quote Link to comment Share on other sites More sharing options...
Torquemaster69 Posted March 20, 2011 Report Share Posted March 20, 2011 I have a similar question. Would 2 Yellow Top Optimas be good enough for two 2600 watt 2 channel amps with a stock alternator?

bignickk Posted March 20, 2011 Report Share Posted March 20, 2011 honestly bro i have the same amp, and i have a ho alt and a khc1400 in the back and its no anywhere near good enough. the amp is power hungry. i would look into a bigger batt in the batt and a bigger batt up front with your stock alt. becuase with only a xs 1200 you will see a lot of voltage drop. hope this helps Quote 2000 tahoe orion hcca 15.4 kicker zx2500 2 JL 300/4s infinity and kicker mids/highs KHC1400 in back, stock upfront dont ask about my HU clarion EQ kicker/fosgate rcas Link to comment Share on other sites More sharing options...
412 CVX Posted March 21, 2011 Author Report Share Posted March 21, 2011 (edited) honestly bro i have the same amp, and i have a ho alt and a khc1400 in the back and its no anywhere near good enough. the amp is power hungry. i would look into a bigger batt in the batt and a bigger batt up front with your stock alt. becuase with only a xs 1200 you will see a lot of voltage drop. hope this helps so what would be my best options? what if i kept stock battery and a d3400 in the back? i mean at some point, wouldn't it be more effective to just invest in a HO alt and get a smaller batt in the back? i've got a max of 400 i'd like to spend on this whole upgrade i'm really not seeing myself going berserk with this whole deal. i could probably only tolerate half power for just daily listening.
