MurderedF150 Posted September 3, 2008 Report Share Posted September 3, 2008 I am planning on running my first "big-boy" system very soon and will obviously have to do the needed upgrades first. I know my main amp will be a RF4000 in order to push 2 15" BTLs....with a small possibility of upgrading to two RF4000's in the far future after i learn more. I already know I need the big 3, some good deep cycle batts, and a new alternator....but about what size alt would be good to go with? Also, who makes some good alternators?

droopy89 Posted September 3, 2008 Report Share Posted September 3, 2008 Also, who makes some good alternators? Powermaster, Iraggi, Mechman, DB Electrical, Excessive Amperage, plenty of choices But yea, the bigger the better, or the more the merrier, or a combination of the two Quote 1997 S10 EC Whats in it 106.9 Sq.ft.

RamenNoodles Posted September 3, 2008 Report Share Posted September 3, 2008 For 2 RF T4000, you might want to look into 2 HO alts. Those amps will pull alot of current, especially if you plan to step it up to 2 later down the road.

The same question, over & over. Not a drop of vehicle info. Is this system going into your Mom's old Yugo, as soon as you get it off the concrete blocks it is resting on? Or is it going into you brand new Viper as soon as it is delivered? Since you can't seem to tell us what Year / Make / Model / Engine the vehicle is you plan to upgrade the alternator in, all I can do is guess. even within a single model & year, there may be 3 or 4 different alternators available.

MurderedF150 Posted September 4, 2008 Author Report Share Posted September 4, 2008 Yeah, sorry I forgot the vehicle specs, I've been strung out with work and getting ready to get married on Saturday.......at this point I think I am losing my darn mind Quote Link to comment Share on other sites More sharing options...
missinglink Posted September 5, 2008 Report Share Posted September 5, 2008 2008 4.6L V8 F150. Your stock alternator is a 6G ford unit, rated @ 110 amps. The modular fords have a center mounted alternator, and not much else will fit in the space. A 6G is available rated as high as 140 amps from the factory. Some people retrofit the older 3G units to the 6G equipped engines, but in your case this will be a no-go. The 2007 & up F150 has a CAN bus connection to the alternator. The computer controls charging, and there is no stator connection for the 3G type alternator. A high output 6G could be built, but you should be wary of anyone that claims more than 200 amps from that case. Once you go past 200 amps, the alternator will have poor output at idle, and will run very hot. A n upgrade to 150 amps or so is much more reasonable for a daily driver.

If that were the case, 150 amps at idle is a piece of cake at 260 amps peak... Quote 1-888-MECHMAN www.Mechman.com [email protected] Link to comment Share on other sites More sharing options...
