thats my cd player....so can someone give me easy step by step to set up the gain going by voltage

RE: voltage?
that last post a put has a link to the gain setting....read that and see if it makes sense to you and let us know.
one other thing....voltage isnt gonna have anything to do really where your gains are gonna be....its like the higher your voltage on your deck then the lower your gonna need to turn your gains up on the amp.

RE: voltage?
is it at all possible that gains that are set too high could create noise when there is no signal going to the amp? even if the head unit is off my subs make noise. sounds kinda like wind on a microphone. only happens after the amp has been on for a while.
my appologies for threadjackin. ha

Next we will be using a basic formula to figure out where the gain needs to be set.
For this you need to know how much power your amplifier is rated at.
We will use a 2 channel nine.2. It is rated at 400 watts by 1 at 4 ohms when bridged.
The formula is sq root of Watts x resistance(ohm load)
400 watts by 4 ohm is 1600 then we find the sq root of 1600 which is equal to 40
We now know that 40 volts is equal to 400 watts.
how do i use that formula for my amp
»80 watts RMS x 4 at 4 ohms»125 watts RMS x 4 at 2 ohms»225 watts RMS x 2 bridged output at 4 ohms

RE: voltage?
this link that im putting on here might be a bit easier for you...i did it this way and it was alot better...when you go to method 2 and go about halway down you will see 2 sounds clips that you can listen to...one is what a clean signal sound like and the other is dirty...burn a cd with a 1khz tone on it and use that....the rest will pretty much tell you what you need to do but you want to still get that clean noise and get the dirty one and then turn it down just below that to get back to the clean signal.....maybe this will help you out a bit.
