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.
