How can I get the most out of my system?

theonenandrew · 25th June 2011, 12:59 PM

I want to get the most out of my system but I don't know what the best settings are for my amp. I have a Sony Xplod 1200 watt amp hooked up a pair of 12 inch MTX Terminator subs rated at 1200 watts, 400 RMS. Everything is run off a Sony CDX-GT510 with 2 volt preamp voltage. The settings that I'm talking about are: level (gain) / low boost (40Hz) / filter / LPF. So should the gain be half way since the amp goes from 6v to 0.2v with 2v being the half way point? I'm not using the low boost because the head unit has low, mid, high, and a separate sub settings on the e.q. Any other help would be greatly appreciated, thanks!

Set the volume at 75%-80% (right before you can hear distortion) then set the gain on the amp all the way down, and slowly go up (clockwise) untill it starts to distort then bring it down just a tick. You this will be your maximum gain before any distortion kicks in. If you have the gain too high you will notice distortion and maybe the possibility for the amplifier to clip.

What type of enclosure do you have for the subs? This will greatly determine how loud you will get.

The subs are in a sealed box

With that HU you'll probably go between 1/3 and 1/2 on the gain knob but the second poster's directions will be fine. I would not go over half way.

For an enclosed trunk run 12db/octave lpf at 80 or 90 if its a stronger crossover.

For open trunk / hatchback try and get a crossover stronger than 12db/octave and set it to 80.

Bass boost no more than +4~6db.

If you have a sub-sonic filter set it between 15 and 25 hz.
