Increased HU voltage

Is there any way short of a new deck to increase the voltage from you preamp on the deck. My current deck has 2.5 volt preamps and I would like atleast 5 volts. Thanks for the help.

line driver audiocontrol makes very good ones.

Would increased preout voltage increase the loudness of my subs? My subs move plenty of air, and my box is not oversized, I just do not get very loud in the cab of my truck.

what is your setup? and i have gained about 1 db using an 8v linedriver

A line driver will not make youir subs louder. It simply give the amp a cleaner signal to work with, and alows you to turn the gain down so the input stage doesn't have to work as hard.

I am sure there are a few situations where a slight gain might have been noticed, as in bill's case, but don't expect this to be a rule of thumb.

buy some sound deadener and deaden where ever your rattles are occuring. i prefer secondskin (http://www.secondskinaudio.com) damplifier and sludge. I had huge (imo) gains when i [deadened my trunk..

If you brought your voltage from 4v to 8v, you would be able to set your gain higher, and give yourself a lower noise floor, correct?

actually you set your gain lower. but it helps keep noise out of your system. and i would say the only way you could gain DBs by using a line driver would probaly be clipping the amp.
