romance Posted July 12, 2009 Report Share Posted July 12, 2009 So, my question is, Can i hook my amplifier power wire up to my alternator directly? i drive a 2002 dodge neon, Im pretty sure it has an external reg. So if i did hook it up with my power wire direct to the alt. What would happen? With an externally regulated alt, IS voltage be "Decided" at the B+ terminal of the alt, or AT the external reg? I dont want to chance having my amps F**k up because i hooked them up to the alternator. (also, if it helps, there is a bettery in my trunk separating the alternator, the power wire, and my D-Block.) So is this safe? Quote Link to comment Share on other sites More sharing options...

No you need to have a battery between your alternator and you amplifier.....your alternator doesnt put out all that amperage in a flat curve...it ripple charges and bad things will happen if you do decide to try it.

Sweet. Thats very helpful. So i have a separate bettery in my trunk, which is fused 3 times before it touches my amps. That should work excellent. But what about the regulator thing? Is the voltage decided allready when the electricity leaves the alternator? Or is it decided AFTER it leaves? Kinda like a power inverter deal.
