xtremerevolution Posted June 8, 2011 Report Posted June 8, 2011 (edited) As we discussed in the last thread regarding how much wattage you can run on a factory system, we noticed that our factory 105 amp alternators are not capable of producing enough power to feed a JL Audio 1000.1 amplifier, with wiring and the alternator being the two key issues. To resolve the alternator issue, there are, fortunately, factory replacement options that we can embrace. Fortunately for us, GM used the same mounting points for multiple alternators . The common CS130 and CS130D used in many of our cars can be replaced with the GM CS144 (or CS-144). The CS144 amplifier comes in varieties that produce from 140 amps to 200 amps, with supposedly a 250 amp model also available. These can typically be found in larger cars and SUVs. The following link will outline the available models: http://www.alternatorparts.com/cs130...uv_upgrade.htm If anyone is considering running over 500W of amplifier power, you will certainly need to consider upgrading your alternator. I will be doing more research in the next few days on which cars you can pull these alternators from at a junkyard for cheap. If anyone has any particular range of models off the top of your head, please list them. Edited July 12, 2017 by digitaloutsider Fixed formatting. JOHN GTPPRIX 1 Quote
pwmin Posted June 8, 2011 Report Posted June 8, 2011 intersting...nice thread. btw, you said "multiple amplifiers"...pretty sure you meant alternators Quote

white4d96 Posted June 8, 2011 Report Posted June 8, 2011 I also heard the AD244 should fit in place of the CS130D and that it is underrated from the factory. I haven't seen any proof but... Quote
xtremerevolution Posted June 8, 2011 Author Report Posted June 8, 2011 I also heard the AD244 should fit in place of the CS130D and that it is underrated from the factory. I haven't seen any proof but... It probably provides more current at a lower RPM, thus giving people the impression that its underrated. Who knows. I'll be going to the junkyard soon as I've realized that my 105 amp alternator and my 1000W amplifier probably aren't getting along. On that note, you should be in the same boat. Quote
RobertISaar Posted June 8, 2011 Report Posted June 8, 2011 i'm always up for "factory" upgrades.... i would personally look toward anything with a cadillac badge on it from ~93 upwards. those SHOULD be CS144s, but no idea on output, may vary depending on model/options. Quote

I have a batt that's about to die, I think that's most of my problem. WHen I was running the MTX and a 2-channel I had a marine batt in the back to supplement the front batt and my voltage was rock solid unless I sat at idle full tilt for like 10 minutes. Quote
ManicMechanic Posted June 8, 2011 Report Posted June 8, 2011 Good link. I need to get something better for the Indy. Quote
RobertISaar Posted June 8, 2011 Report Posted June 8, 2011 rockauto is showing nearly every N* application to use a 140amp CS144 from the factory. Quote
ManicMechanic Posted June 8, 2011 Report Posted June 8, 2011 My Silhouette has a factory 140 amp CS144. Quote
ManicMechanic Posted June 9, 2011 Report Posted June 9, 2011 Yes sir. It's funny in the movie, when Danny DeVito pulls up to the restaurant in a dark teal Silhouette, a closer look shows it's a 1994 Lumina APV with Silhouette stripes and wheels. Quote
RobertISaar Posted June 9, 2011 Report Posted June 9, 2011 assuming we can get a list going of CS144 equipped vehicles(and preferably their output ratings as well) that will work, the next logical step would be to determine which is the easiest vehicle to pull them from. Quote

Hell yes. You guys are one step ahead of me. Making it all the easier to get high output alternators without having to spend $150+ will bring us all closer to better sound systems and other means of insanity.

Crazy K Posted June 9, 2011 Report Posted June 9, 2011 I had been looking at 97-98 U-vans as a source for alternators, as they have optionally a 140 amp cs144D and going from a 3400 onto a 3100/3.1 should be straight forward. Quote

Ditto. I am planing on getting a U-van alternator when i get a UDP. The U-van alternator should have a pully size that is 1 inch bigger then our 105 amp alternators. (Or so i have been told) So if you ran both at the same time there would be no need to get a longer belt for the U-van alternator. Quote

xtremerevolution Posted June 9, 2011 Author Report Posted June 9, 2011 Any idea if there were any cars that came equipped with larger than a 140A alternator? Sounds crazy, but to run a 1000W amplifier to its maximum potential, we need a minimum of 150amps on the alternator. Quote
RobertISaar Posted June 9, 2011 Report Posted June 9, 2011 the most powerful factory CS144 is either 140 or 145 amps. Quote
xtremerevolution Posted June 9, 2011 Author Report Posted June 9, 2011 the most powerful factory CS144 is either 140 or 145 amps. Is there a more powerful alternator available that would also be compatible? Quote
