How Do I Turn Down My Amp

vms150 · 09-08-2006, 12:41 AM

Well I lack much knowledge in the audio field so i have no idea what i'm doing when it comes to adjusting my amp. I was running 2 RF Punch 2's but since I have killed the saturn and am now driving my jeep I made my own fiberglass encloser and will only be running one sub. The amp is a 1200 watt xplod. Any advise on turning it down to 250 watts and tuning it a little?

just keep the gain down, and you'll be fine.

LPH= Low pass something.
Both the switch and filter knob are designed to tell your sub which frequencies of music to play. If you turned it all the way to the left, you probably wouldn't hear anything...as you went around the dial, you would start to just catch the bass drum kicks/lowest notes, followed by the low end of the bassline (lmao, typed lol end of the baseline), and then it would almost sound like a regular (crappy) speaker near the 5o'clock end of the dial.

maybe.

lpf is low pass filter, and without it you'd need either an electronic or a passive cross-over. as long as its on then you get bass, if its off then you get the full sign wave amplified. and the filter is the frequency at which your low pass filter, filters the music. By playing with the level and or boost you should be able to dial it in.

Your running it bridged currently. If you want only 250 watts to your sub just use 1 channel of the amp.

What's the model number on the amp? I can almost guarantee that it doesn't put out the 1,200 watts it advertises on the front label.

What sort of sub (make and model) are you planning on running?

1.) "Level", or "Gain".
-Find out what voltage your RCA output on your head unit is. Example, my deck has 4V pre-outs, some other manufacturers might have 2V pre-outs. Find out what your's is, and match your "Level" knob to that number. If you've got 2V pre-outs, set the dial to "2".

2.) "Low Boost".
-This is just an additional equalizer setting built into the amp. It increases output at 40 Hz (low bass notes). I'd recommend setting this to "0", especially if you've got a ported/vented box. If you've got a sealed box, you may want to turn it up, but I personally wouldn't go over halfway up.

3.) "Filter".
-This is the LPF, low-pass filter. What it is, is a crossover. It limits the frequencies to your speaker to only bass tones. When set to "110", your subs will play frequencies 110 Hz and lower with no interference. At a point higher than 110 Hz, the sound will be cut by a certain level... Typically 12 decibels per octave. Meaning that a 220 Hz, it would be 12 dB quieter than at 110 Hz, at 440 Hz, it would be 24 dB quieter than 110 Hz, at 880 Hz, it will be 36 dB quieter, etc... Other crossover slopes would include 18 dB per octave, or 24 dB per octave.

I'd recommend setting the "Filter" to "110", or maybe somewhere between "60" and "110", leaning more towards "110".
