Hi, I am looking for a recommendation for my car. Its a 2001 Lexus IS300. There isn't a configurator online and i'm trying to get something specific for my application. My car electrically has: Viper 5902 w/autostart w/ 3 Extra Sensors (Glass break, Shock, Wheel Sensors) Avic-Z110bt Headunit w/ a few modules (HD Radio, Backcamera etc.) Sundown SAX-100.4d Focal 165VR Components for the front SI BM MKIII 12 Subwoofer Headlights and Foglights both w/ 55watt HID Ballasts Valentine 1 Radar detector and stealth display I'm looking for something that is a little bit lighter if possible, but can handle all of this and last a long time Also I am looking for something that aesthetically looks like the optima red's structure, so that it looks symmetrical as a square in the battery holder in my engine bay. Thanks a lot! Hiral Hiral
