Factory cheap alternator upgrade

[xtremerevolution]

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.

intersting...nice thread.


btw, you said "multiple amplifiers"...pretty sure you meant alternators

Thanks for catching that. Fixed!

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.

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.

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.

Good link. I need to get something better for the Indy.

rockauto is showing nearly every N* application to use a 140amp CS144 from the factory.

My Silhouette has a factory 140 amp CS144.

Silhouette

Cadillac of minivans.

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.

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.

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.
