current draw?

how much amps or rms is two jbl 1200.1 bp mono block amps. i am running each amp to a pair of kicker comp vrs 2 ohm subs wired down to 2 ohms to each amp. so 4 12s in all with each amp running a pair. im looking for my rms. i am using 4 guage power from battery to block with four guage cable to each amps. tonight i ordered 0/1 guage wire with 300 amp stinger fuse and a distruibition block running 3 four guage wire.need help quick because i feel i should pound louder then i am, i also ordered an 225 amp alt to help out. so will the new power cable improve my power for the amps until my alt arrives?

how are you wiring the subs down to 2 ohms if they are 2 ohm subs? Are they dual voice coils? That would make sense that way. Anyways, yea, for 2 of those, you are probably not getting enough juice to each one if you are using 4 gauge and splitting to two 4 gauge wires. What kinda boxes do you have those subs in? Are they built to spec? Is the car rattling like crazy or did you do some sound dampening? From the sounds of it, 4 12's in anything with that much power should slam like crazy. Just find the weak link man.

ya they are dvc so i wired them up to 4 then dropped the ohm down to 2 ohm. i dynmat my whole trunk. it pounds but not like it should. now when my new power cable comes i hope that fixes the problem because i using 4 guage with 150 amp fuse now im gonna use an 300 amp fuse and 1/0 guage. should that give my amps more juice?

If you check this chart, which does err on the side of bigger is better, then yes.  The larger wire would carry the current these amps are trying to pull.  You'll know it when the larger alt is operational.  Until then there may not be a difference.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

so even after i instal the new power cable i wont notice an difference in the sound level?

installing the power wires might help the amp a little, but I doubt it will make any considerable difference. The only thing you will be doing is helping you amp live a little longer by making it struggle less. As it stands, you are overpowering those subs quite a bit, so, if anything, i'd say your subs are the weak link. or perhaps the enclosure they are in. what kind of box do you have and how is it built? Is each sub in its own chamber? are they ported or sealed? also, what kinda car do you have them in? do you have them facing in or out? facing the subs in a different angle could help. there are too many variables. you're gonna have to give me some more info on your setup, so i know whats up.

the subs are in an custum made 3/4 mdf box with each sub having its own chamber. also the box is sealed . the subs are in an 70 buick skylark droptop with the subs facing out. right now my power cable is 4 guage with an 150 amp fuse at the battery and my alt is 140 amps 100 at idle and 174 at 55 mph. i had autozone test my alt and it is underated they said so it puts out more amps then advertised. oh by the way its an proform alt

have you guys ever heard of upgrading the big three? and if you had does it work?

You said you're looking for the RMS.  You can measure it yourself, first get a digital multimeter.  Read the post 'Amp Calculations' for info on how to do it.

Just a guess on the big three question:  I would think 1) battery ground cable 2) alternator 3) battery
