1 or 2 band Parametric EQ w/Q control for subs?

[sportyaccordy 10+ year member]

I want a one or two band EQ or crossover for my subs that has:

-Frequency selection from 20-100Hz

-Q-factor control

-5-10V RCA line output from a 2.5V input

-12dB or better selectable lowpass

If anyone's familiar with Alpine's MRV-1507 or I guess any of their bass amps they'll know what I'm talking about. Most amps have a lowpass and 'bass boost', and mine even allows me to pick the frequency at which it works...but not the Q. I was just curious to see what was available.

Kenwood Excelon amplifiers and head units have the "Q" ajust option.

Yeah my HU has it too, but it's all very ambiguous and within a small range. Plus I have my amp, subs and HU so I don't really wanna go through the hassle of changing everything...I'd rather just add the EQ onto the system.

Found my solution...it's a line driver with a remote bass parametric EQ. The only problem with it is that it has an 85dB SN ratio, which is fine for my subs but not good for my components. My HU now has an SN of 94dB and 2.5V outputs...I used to have an HU with an SN of 86dB and it sucked. Would this line driver hurt my component's SQ?

so what the hell does and adjustable Q do for subs and compnents...for i i think it being changable helps with differantboxes but what else?

what q does is it adjusts the width of the bass boost, and when tuned right with the box and parametric equalizer, will help achieve audio nirvana. Have you ever seen a dyno test for a car's horsepower? Well the q is like the powerband, where the horsepower is strongest and where it peaks. Make more sense? It helps in yor sub's weak or strong areas.
