Pravinesh Singh Posted March 19, 2016 Report Posted March 19, 2016 I'm running a 1500 watt D class MTX amp running at 2 ohms thousand watt RMS with 200 watt 4 channel MTX amp I got a second battery in the trunk and I got a Rockford Fosgate power 1100 RMS 15 inch T2 Fosgate dual fours in a enclosed ported box I'm still running a stock operator with his hundred amps I need to know how big of a alternator do I need so my music don't cut off... I need some inputs please
Pravinesh Singh Posted March 19, 2016 Author Report Posted March 19, 2016 Also I have 2400 XS power battery in the trunk which seems like it's just not enough my alternator is not able to keep up with my two batteries
Lakeshow94 Posted March 22, 2016 Report Posted March 22, 2016 so is that 3 amps or two? I have a gs300 and I'm currently running 3k rms off of a stock alt and two big agms. The lowest I see is 12.8 (waiting to install my alt). I would recommend doing an alternator, talk to singer he makes a direct fit. 1999 Lexus GS 300 Pioneer DEH-80PRS Singer 240 Amp (Will be installed later) Northstar Group 31 & 24 Sundown SCV-4000 Rockford T400-4 2 12" CT Sound Meso CT Sounds 6.5 Meso Components CT Sounds Tropo 6.5
