noob question (im sure im not the only one who doesnt know) but what does "active" mean???

And how would you know if a amp is active capable?

active means you no longer need the crossovers that comp sets include you would use the crossovers on the amp to do that job. Well its more in the headunit but the low pass high pass and if available * not on most* a bandpass filter most dont have them but instead have high and low a band pass is a combination of hi and low basically that cuts frequency above and below the given range

more easily achieved with an active headunit that is capable of high and low pass crossovers and the abilty to split signal to High range(tweeter) mid range(mids and midbass) and low range(subwoofer or other woofers)

And what is time alignment?

adding delay to a speaker or set of speakers so that the all sound reeachs the desired listening position at the same time

Look for a Arc Audio KS 300.4 amp. You can run fully active & it has a 10x multiplier.. Will do 90x4 @ 4ohms (13.8v) , designed by Zeff (Zapco), Class G/H over 70%+ efficient, great amp!!

Wow, good deal on the poor cosmetic ones... You can always paint it... I may think about getting one myself.

To far above budget 350+ for one is a tad to much. The 100.4 has my attention since I will be running all channels at 2ohm anyways and

160x4@2 should get my FS loud.

The KS 300.4 will do 175wrms x 4 at 2ohm. you can buy them used for a lot cheaper & they are very reliable amps... I see that you already PM'd somebody...

Be sure to read a independant review from a professional...

Yes it was. 3 way to be exact (2 way front stage + sub).

OP I have an old school BNIB LA Sounds 4 way crossover if your interested in doing it that way.
