if i have my lights and a/c on at a light my volts drop a little. i have pulleys and two 10' subs. if i replace my alt what amp would you suggest?

i dont know what full load means. if i had to guess i would say all the accesories on.

i went out there and got 14.2. with all accesories on it goes down to 12.1, is that normal?

Is this with the stock gauge, or are you using a multimeter and probing both battery terminals? 12.1 is too low, unless the battery is not charged.
A 130 should suffice. They added a lot of alternator just for the electric fan, so I would assume you have some left over....

12.1 is at the battery terminal. another thing that i can notice is with the a/c on max it gets weaker when the volts drop, but then when i start driving it blows a little bit harder.
The fan speed thing is normal for me too (my idle is 700 RPM). But as Scott said, those volts are no good. you should be about a half to one volt higher with a full load.
Many parts stores can test the system if you stop by.
Otherwise, a bad connection, battery, alt, etc can cause issues like that.
Good luck.

That'll do it...a 200 will work everytime. I know there are some aftermarket companies online that sell 160's
