alright i need this to be as simple as possible i was told i need to set my gain so that the voltage was 17.88 volts but that was wrong...can someone please tell me how to set all the setting on the following amp with the following speakers...i know the procedure of setting the gain i just need to know the correct voltage i need to achieve.

Polk 6.5" Component System DB6500 - 40hz-23kHz -100 watts RMS - 300 max
Polk 6x9 3-way DB690 - 35hz-22kHz - 100 watts RMS -300 max

Profile 80x4 amplifier. http://www.crutchfield.com/S-x0NdOzEy5Ef/cgi-bin/ProdView.asp?g=120&tab=morephotos&pi=4&i=489AP1040&display=XL#Tab

If possible, if anyone of you are truly ingenious, can you tell me where to set each of the crossovers, and how much voltage I need to have the gain set to.

Also simple step by step gain/voltage setting would be nice. People have posted this long things that just confuse me. I would like a nice short typed up procedure by a person, in simple words.

Forget the voltage settings.

Turn the gains all the way down. Turn the volume on the head unit all the way down. Turn off ALL bass and treble boost and put the crossover to FULL.

Now pick a CD that is recorded really well and best represents the type of music that you listen to.

Now turn up the volume on your head unit to about 75%.

Now turn up the FRONT gain on the amp til the speakers start to distort slightly. Then back it down just til the distortion stops.

Now begin turning up the REAR gain until it blends in well with the front speakers. Youre done.

Now I wouldnt use the treble boost at all and only a no bass boost either, especially without a sub. So leave both of those off.

Now set both front and rear crossover to LOW PASS. Start off with the dial at the 11 o'clock position on the front channel and set it to 50 for the rear channels.

This will be your baseline settings for crossover and you can tweak em a little if you feel the need.
