Active compatable amps

this one is even more fun..Rockford Fosgate 3Sixty.3 Programmable 8-channel digital signal processor at Crutchfield.com

I saw that before, there isn't much that it can't do!

A bare bones active capable amp must have adjustable midrange xovers. 2 channels for the mid/mid bass, and 2 for the highs. You want to band pass the mid/mid bass signal, so if your amp can't, your deck needs to have flexible hpf xover settings. Let's say you want the mids to reproduce the 80 hz to 4khz frequencies... You put those on the amp on the lpf setting, and the xovers set to 4000 hz. Then you set your decks hpf to 80hz. The highs will be on the amps hpf setting, xover also at 4000 hz. This would be for a two way setup though.

It is cool...each individual speaker channel can be programmed for timing, x-over and equalization. The idea, as advertised, is to simulate a pair of quality headphones as the listening environment....a little far fetched....or not? For the $, it is really a good deal, for what it can accomplish.

If I'm correct amps able to be "Active" have LPF, FULL, and HPF where LPF is your subwoofer, FULL is your mids and HPF is your highs/tweets, some amps iirc have just FULL/HPF? (also sometimes called Bandpass)

Band pass means just what it sounds like. It allows a specific ” band” of the frequency spectrum to pass through the filter. Let's say you want to play only the 2.5 khz to 5 khz frequencies, for whatever reason. You would xover the amp, deck, or both to allow only that range to B be amplified.

Thanks, that was kind of what I was thinking... A guy told me that his amp was unable to do active so I was curious.
Is filtering the only criteria? Could an amp with no filters (full pass) be able to do active if you had a head unit that was able to filter the signal?

If your hu is bad azz enough, then yes, you can use amps with no xovers whatsoever.

The p99rs cannot let you control the eq for each channel, the fact that it can do that is impressive. I agree it is a pretty good deal for the money, pick up a nice SQ deck and let that thing handle the rest. Right now it would be overkill for me, but I would still like to see what it can do first hand.
