Some amp terminology
K i got an alpine MRV-100M amp and a 12" Type S sub. I was just wondering what some of the settings on the amp do. Like phase and LP filter? like for phase, what do the 0 degree adn 180 degree settings do? the manual didn't really explain it that well, thanx.

Re: Some amp terminology (Slain)
How I tune bass:
Set your volume of your head unit to your NORMAL listening level. Turn your gain (volume) of your sub amp all the way down. Turn your LP (low pass) filter to its lowest setting. Sit in your drivers seat. Turn all other speakers off other than your sub. Play a recording of a repeating, low bass sound (ochestral or jazz bass lines work best, like a repeating bass drum hit at the begining of a dirge)
Now LISTEN
Switch your phase and listen. When was it louder? The louder phase is the correct one.
Now turn your other speakers on and turn your gain of your sub amp up SLOWLY. Listen very carefully. When the bass just starts to be noticed, turn it up a bit more, until you notice seperation in the sound quality (ie sounds like the bass is coming directly from the sub) then turn it down a bit. The key is that you want the bass to sound like it is surrounding you, not just blasting you in the back of your head. Now turn your LP up just until the bass and the treble "touch" each other. You want the subs to pick up the sound where your mids drop off. Many people just set their LP to 80 or 100 Hz, a mistake in my opinion. Usually 45 Hz works pretty good, and I consider 60 Hz to be a high setting. Now sit back and enjoy.
NOTE: There is more too it than just what I have described (high and mid tuneing are just as important for a fine sound quality.
NOTE 2: If all you desire is tooth rattilin, old people scarin bass, set your LP to 80 Hz and turn your gain up until it distorts and enjoy the crappy bass. It will be loud tho...
