new guy Posted April 5, 2012 Author Report Share Posted April 5, 2012 im pretty sure that most all fords have a pcm controlled alt. so unless your bypassing that your not going to use the full power of your alternator. even then on a stock electrical your alt probly does maybe 100 amps. your cars probly using 30 amps to run.. so 70 amps left for everything eles. there goes your 700 watts. yeah i know theres gonna be voltage drop on a 1700w amp on stock electrical i was just wondering why it drops straight off from 14.8 to nearly killing my car. and no big 3 yet. i got a battery for you if you need it pm'd Quote *current* 1991 honda crx si 2 skar audio 12s pioneer 6.5s dual 400 watt amp audio technix db 1/0 wiring kit. dual head unit Link to comment Share on other sites More sharing options...
Decaf Posted April 5, 2012 Report Share Posted April 5, 2012 you sure red lead is on AMP + input where it should be and not measuring the remote wire + input remote wire voltage remains rather constant Quote Link to comment Share on other sites More sharing options...
Noobtastic14 Posted April 5, 2012 Report Share Posted April 5, 2012 you'll never see the full 1700 with that amp anyways. Its rated at 14.4 volts, which means you'll need to constantly be charging and staying at 14.4 volts to sustain that 1700 watts, and even then you won't see it cause amps aren't 100% efficient. The efficiency is taken into account when placing a rating on an amp. For example, the amp does 1700wrms @14.4v @85% efficiency -Drew Quote I am a United States Military Arts and Crafts Professional.
