...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.

Thanks GW and B in advance ;P

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..

if you have a ported box...set the subsonic filter just below the tuning of your box (ex...box tuned to 30hz, set the SSF to 25hz)

also, set your low pass filter to ~80-100hz.

that boss amp will prolly produce about 1000-1200wrms @1ohm. it has the same internals as

. Concept CC-D1200
. Lanzar Vibe 1200D
. Pyramid PB2400D
. Tsunami GXA1000D

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.

It's a slot ported box, don't know the frequency though, the shady internet dealer didn't know.. but its a "Ground Shaker" brand enclosure. It's ~2 cu ft.

Right now the SSF is all the way down, so I'll move that up a little to estimate 35 Hz, but what about the low pass.. 80-100 or 60?

set the low pass at 80hz. That way it block freq above 80hz, and give you the lows..
