anybody with good electrical system knowledge should def give a guess on this one. My stock alt is 120 amp's and im running regular range rover electronics and my kicker KX350.2 which has a 50 amp fuse. now im wandering how much power my massive P3000.1 is seeing before it drops to battery power? im guessing about 1000 watts tops, but who knows, im not that educated in the electrical field so i was hopin someone who is (MS,Wolfie,paul,Polo) or anyone who wants to guess could help out.
first off u ahev to see if it has a regulated power supply or unregulated...
but with your charging that amp if it has unregulated power supply and because its pretty damn efficient with 85% of efficienty ull see close 200o watts if u got enough charging system toback it up witout using the an ho alt like beefy cables good batterie in the hood and if your battery drops to at least 11.5 volts
if u got pretty much stock ur screwed u better set the gains rigth cuz that probably wil be clipping 90% of the time
heres how my calulations came out. 120 amps - 20 for car needs =100 - 30 amps for Kicker mids/highs amp. so thats 70 amps 8 13.5 (what my vehcile sits at) X .85 (efficiency) equals about 800 watts
im guessing about 1000 watts tops, but who knows, im not that educated in the electrical field so i was hopin someone who is (MS,Wolfie,paul,Polo) or anyone who wants to guess could help out.
Sorry, but I'm only educated in the electrical field as it applies to house current and plugs/switches/lights in homes...so no Idea on this one.
14.4*85 amp (usable)= 1224 is about the most you will see total, give or take. 1224-20 amps for kicker amp=1200 or so. 1200-20% for loss is -240 amps for a total of about 1200-240 =960 amps. So your guess of 1000 was pretty close.
Throw a dmm on it and find out for sure. This is all speculation. If your wiring was good, If your bat/alt was good. If your equipment was effecient....

Lol,only 20 Amps for your car's needs?Come on man you think they'd install a 120 amp stock alt in there because your car only needs 20 amps?You need to have a look at the fuse panel and do some thinking.
yeah, i got what ya mean. like i said still pretty new to the electrical arena. so how many watts do u think im seein rob? (remember to allocate for the mids/highs amp)
the battery acts someimtes like abuffer then when it draws all the alt power the battery will push the extra amps needed but not sometimes when it needs alot more current.
so
its 14.4*85 amps (usable)= 1224
but then add another 85 amps from the battery 2380 rms
Most of the calculations in this thread so far are BS.......
If you want to know how much power you're getting, use a DMM to measure your electrical system voltage. Crank up the system and see what it drops to. For example if you amp has a 12 volt power rating and your voltage is dropping to 12, that's how much power. If it drops to 11, figure a little less than the 12 volt rating. (of course this all assumes your gain is set correctly)
But if you just wanted a guess, I'd say you could probably get about 2000 watts with massive voltage drop (not good for the electrical system).
120A at 14.5V (suggesting it doesnt drop) Ill give your car 20A running power..
100A x 14.5 x.80 (80% effientcy?)
1160rms but since it will drop down to about 12.6 where battery power kicks in this is what you would get at 100A x 12.6V x.80 = 1008rms
rought guess's... but then you have the kicker as well to factor in.. about 800rms? but the battery power keeps it from being 700rms.. your out of power without them lol
