soundstream15 Posted July 27, 2013 Report Share Posted July 27, 2013 my stock alternator is 105amps, i have a optima under hood and ketniek hc2400 in the back, big 3. now some ppl say i shouldnt get a bigger alternator and just get a third battery so 2 batteries in the trunk. but doesnt that mean more strain on the alternator? if i get one im gonna get a mechman 170amp for 300$ volts do drop to high 11s and my amp is 3k i just hear so many mixed things, its not even funny, maybe just my hc2400 sucks and i need xs power lol Link to comment Share on other sites More sharing options...

will77530 Posted July 27, 2013 Report Share Posted July 27, 2013 if your system demands more current than your altenator can produce you need a bigger alt. if your system is pulling more than your alt can produce regardless of how many batteries you have you will have voltage drop, may not go below 12 but wont be 14 Link to comment Share on other sites More sharing options...
Karkov Posted July 27, 2013 Report Share Posted July 27, 2013 My stock alt was 160 and I swapped it out. if i was you I would swap alt and then see where your voltage is at while playing stereo 2007 Chevy Tahoe (SOLD) 12 ~ FI Audio X series 10" w/BP option 2 ~ DC Audio 5.0K @0.67 3 ~ DC Audio 5.0K @1.0 2 ~ PPI 3 way sets (not installed yet) 1 ~ RF T400-4, 1 ~ RF T600-2, 1 ~ RF T600-4 4 ~ CT Sounds 5.25" Strato comps (rear fill only) 1 ~ XS Power D4800 1 ~ XS Power D3400 8 ~ XS Power XP3000 160 stock alt, Mechman 370 Elite, 185 DC Power 320+ Sq.

soundstream15 Posted July 27, 2013 Author Report Share Posted July 27, 2013 good points made. thought about the 220 but thats 400$ pricey but guess you gotta pay to play Link to comment Share on other sites More sharing options...
TeamHT Posted July 27, 2013 Report Share Posted July 27, 2013 In this case I would do the alternator and see how your voltage is and then vote from there. Tell me...does this smell like chloroform to you? Link to comment Share on other sites More sharing options...
