...is what I would say if I wanted lots of people to view this thread... hahaha. Seriously though, I have an old Boss Rev-3000D Amp hooked up to a 2 ohm DVC Mofo-12 sub. This amp has 3 adjustments; Level (set at 3/4), Low pass crossover, and Subsonic filter. I took it in to best buy to have one of their installers set the low pass and subsonic for me, because I really had no clue where to set them. I am now convinced that they are set incorrectly. Can anyone tell me where a "safe" position on each setting is to get the most out of my setup?
Need more info? let me know. I know the subsonic values go from 15 to 45. And the low pass goes from 20 to.. 200? I think.
Oh, and when bass hits the lights dim A LOT, so I know the amp is still dishing out a ton of power, but on certain bass notes it hits hard, and on others the sub will excurt a lot but not produce any noticeable sound. So I have a feeling I am playing it into clipping like a dumb a$s..
the issue with the lights is probably due to the current drain from the amp. use a volt meter to see how low voltage is dropping when it happens. if it falls below 12V, consider a larger alternator, and a capacitor of around 1Fd to act as a filter.
set level at 50%, LPF on, and set to 60Hz, set SSF to 35Hz unless you know the tuned frequency of your enclosure's port. Then set the SSF to that freq.
