tonedeaf Posted August 18, 2011 Report Share Posted August 18, 2011 Mediarocker, the reason he says its a stronger spark is because, although stepdowned, he's always getting 14.x voltage to the car. Never ever dropping below that. With the constant power never changing or fluctuating, it makes it more efficient. That's what he was assuming. Who knows. As for why not a 24v system, to my knowledge there are no car systems or amps that are 24v capable. Not to mention many alternators are limited to around 20v I thought.

woodzyspl Posted August 18, 2011 Report Share Posted August 18, 2011 i think the us amps bonecrusher is 24v but i think comps wont let you burp that high. amps that take 16v would be dc (mine the 9k at 16volt is sick) as for me im chargeing 2 8volt batts to 16volts for burps. i float at 17v higher volts=win wouldn't mind 2nd alt to run 16v tho.

tonedeaf Posted August 18, 2011 Report Share Posted August 18, 2011 How do these step-downs actually work? Any closeup pics of them? How so you run say a few 4 hannels in a 16v setup? Stepdowns and 1-2 12v batts? How do you wire one up and there's like 8 or 10 gauge leads from what I can tell. The step-downs are rated at 25 amps constant, 50 amps max. General consensus seems to be 2 for your older cars, and 3 for your newer cars. If you turn on every accessory in your car you can use a clamp to tell what kind of amperage your using, and know how many you'll need. As for highs amps, I'm with you...I'm wanting a full 18v daily setup since I only have the room for two alts, so to my knowledge the only way to run them is as many step-downs as amperage they can pull. Sadly at $150 per sd iirc, it gets extremely expensive very quick. If I could only run 4 alts. Quote Link to comment Share on other sites More sharing options...
woodzyspl Posted August 18, 2011 Report Share Posted August 18, 2011 don't see why they couldn't make a larger step down? or you could use one and have bank of 14v batts lol Quote AUSTRALIA do i need say more?

Rainman215 Posted August 19, 2011 Report Share Posted August 19, 2011 don't see why they couldn't make a larger step down? or you could use one and have bank of 14v batts lol That's what I'm wondering but 12v would be fine too. Like say can you use a step-down and then use like 1-2 batteries to run the car/ mutli channel amps.

Im actually considering running a couple kinetic 16vs in my XS 16v bank...that way you have the 12v posts for highs and car...not sure how well that would work, but ive seen people mix 12v batteries many times with no problems.
