Wanted to know if there were some starting points for the different settings for a dedicated sub amp.



So far what I've read:



Low pass filter: 80-120hz depending on taste and how much midbass your fronts put out.

Subsonic filter: 5hz below what your box is tuned for.

Bass EQ setting: keep to 0

Avoid using kind of "bass gains" on your HU, pass through to amp and let amp adjustments do the work.



Does this sound correct?

Setup in question is a MRX-M50 amp and JL W3 2ohm with JL spec ported box.



Thanks

 

Those are all good ideas, but none are hard-and-fast rules. If you get a setup that sounds good when following those guidelines, don't be afraid to hit the "loudness" button on the HU for a song or three, just remember to turn it back off to get your SQ back!



Those look like decent parts, BTW. Should be more than enough, unless you are going for 'too much'
