That is not what i found, the alt that they sent me is only rated at 120 amp, which i dont think is enough... Here look at it for yourself.

Will it be louder or will there just be more air pressure???

Uhh, that's basically how loudness is measured, by air pressure. Each subwoofer may sound different, and one even may sound louder than the other but in reality more air pressure should=louder. Sound waves are nothing more than pressure changes in the air.

Also I still have no clue what OHM means?
Should I get the the 1 OHM or 2 OHM, what is the difference and what does it change if anything....

That's the unit for the electrical resistance of the subwoofer. It changes the loads the amplifier sees and it is important in your choice of setups. Do some searches and you will find loads of information on this.

Yes i finally did figure out how that works... But thanks for your help anyway...
Right now i figured out how i have my sub wired, luckily it was correct from the get-go... It is a dual voice coil set up at 4Ohms, and i have it wired so that amp sees it as a 2Ohm..

Does anyone think that 120Amps at idel is enough for something around 3000-3500 RMS??? I will have a separate battery for the sound system, or 2 if needed...
That is the alternatow with the highest output at idel speed that i found at this time. Does anyone know of anywhere with a higher idel rating, if you think i need it??
THx for your time and help!

I would write them back and tell them your looking for something higher at idle, or if you are willing to spend some time doing some minor modifications look into an Iragi CS-144 Alt   I know those are 200-225 at idle I believe and 300 at higher speeds
He has an Ebay Store, but cannot post the link to it due to rules of fourm   search ebay for Irragi Alts or search High OUtput alternators and look in the store section on the left side
