Ive got a Kinetik HC1800 that im trying to get rid of. Bought it the end of last summer and wasnt used until sometime in September when i got my sub from IA.
Perfect mechanical and cosmetic condition. Asking $150.
Also have a H/O 275amp Singer Alt that is for use on Chevy cars. Cross reference to a 2003 Monte Carlo SS to see if it will work with you vehicle. Got both pulleys for the alt as well.
EDIT: IT WAS SUGGESTED THAT I ADD A PIC SHOWING VOLTAGE, SO HERE IT IS
