ok.. quick question.. after u install one is there a decrease in the output of the altenator? reason im asking is becuase i was thinking of getting one but i have a fairly large stereo system and need all the output from the altenator as i can get. anyone know the answer to this for a fact? thanks in advance..

 

yes

 

if you have a system of any size, don't even consider the underdrive pulley. I have one and love it, plus I got tired of my 12's and sold them.

 

ok.. thanks guys

 

Where did you get this information?! On the contrary, I have the UDP and two amps (RF 400a4 and 500a2) for my sound system and I noticed ZERO power/bass loss before and after the installation of the UDP. I know my setup isn't huge but to say not to get the UDP if you have a system of any size is simply talking out of your behind.

 

does anyone know for sure if theres a power drop or not?? i mean , has anyone done any kind of voltage test or something?

 

There is indeed a power drop, how large, I do not know. I have the feeling that if your stereo is under 500 watts you should be ok.

 

ummm.. what if it was like 2000?

 

No way 2000 watts, your already pushing the envolope on your electric system.

 

lol.. guess that answers that question.. thanks
