GS300 weak electical system...
This may have been covered so forgive me if I'm generating forum clutter but I have a 2002 GS300 and even stock the electrical system seemed week to me. The lights would dim when the radiator fan would kick on when my car was stock. I recently upgraded my audio system and I have two amps in use. I'm running a JL 500/1 pushing two rockford P3's and a SoundStream Van Gogh pushing my components at 320wats.
It seems like my system can barely handle this load. Yesterday I upgraded my walmart battery to a Kinetic 1800 battery. The Specs for the battery are:
# AGM Technology
# Sealed Non-Spillable Design
# Mount In Any Position
# Ultra Low ESR
# More Plates For Stronger Energy Density
# Higher Voltage Under Load
# Tightly Packed Cells
# Superior Heat & Vibration Resistance
# Weight: 54 lbs.
# Ah: 81
# Amps: 1900
# Dimensions: 10" x 6.5" x 8.2
It seems adequate for now but I'm wondering what else I can do to improve efficiency and output. I'm also going to upgrade the big three and I may add a second battery, but I'm also curious about High Output alternators. I've heard about people using Sienna Alternators, or putting the internals from a Towncar in the housing for a GS3 alternator. I'm really just looking to remedy the dimming lights for the most part. Any feedback would be appreciated. Thanks.

That damn garage troll... someone direct me to someone that sells reliable alternators...
caps are garbage, i got a few for sale if anyone wants, i guess I'll fork over the money for a second battery... and look into that sienna alternator...

You should add one more 1800. Don't add a cap. The battery has to feed the cap, the battery is allready having a hard time. Adding another 1800 should be ok. Use 1/0 wiring from the front to rear battery. Also check or make it bigger, the main ground wire at the front battery. No need for a high output alternator. For 2-1800 kinetic is good for 3600 watts so you should be ok. I have a 5000w system and 5-1200 kinetic batteries. Ran it for 2 years with no problems.

Dont forget to do the "BIG THREE"!!! That will do WONDERS for the car. The "Big Three" consists of:
1) Upgrade wire from alternator to battery
2) Upgrade wire from battery to ground
3) Upgrade all your grounds under the hood e.i. block to chassis; block to firewall; alternator housing to chassis
Use 4awg, 0awg preferred. as for hooking up the second battery. Yes use 0awg, put a 300 amp fuse at both ends of the wire. Heres a pic of my upgrade. I Love 0awg, its soo sexy!

I say put the stocker back in, and run BOTH Kinetics in the back! thats what I did! I too am running 2 Kinetics. I know they say not to mix brands, but I havent had a problem yet. (but another Kinetic is next in line for under the hood too...)

did you isolate the ones in back? I was just thinking of throwing a HC800 in the back. The big three upgrade is coming soon although I'll probably use 4awg, not 0/1awg since most of the 0/1 I've been finding is overpriced or really just 4awg with lots more insulation.
