This is probably gonna sound stupid but w/e. I used to work with a guy who has a killer system. I cant remember exactly what it was, but he had a Planet Audio 12" sub, bassworx ported box, Zapco amp with a premier head unit.

One day, he had his car outside the shop and was playin around with one of the guys who said they had a better system then him. He turned up the music and the bass would rattle the locker doors at the back of the shop (24 bay dealership). I asked him what made it pump so much, and he said he had a pre out amp or something like that. Bascially he said that it bumps up the pre amp voltage from what ever the factory is (usuially around 5v) to like 12.

Bascially, I want to wake the dead

P.S. I did try to search, but I dont know exactly what its called, or if it actuially exists and he was just ****** with me

 

Yes, that would be a pre out amplifier. Getting one will not help you if you're running your sub amp at its max. Boosting the signal will only drive the amp into clipping (and probably bottom out the sub(s)), resulting in lots of distortion and damaged equipment. If you want to go louder, get a bigger amp and more/bigger subs.

 

With a properly built system you won't even need one.

+1, with a pre amp you get a higher input voltage to the amp, and that allows you to run your input level sense at a lower level. The signal going out of the amp is only as good as the signal going in. Same with a pre amp. if its a dirty signal going into the pre amp then you will get a dirty signal out. You want the cleanest signal you can get going into your amp. Period.
