I have a G190 and wonder how clean it is, I replaced amp and drivers when I dropped it in so could not compare much. I had a nak and it was really clean. Just wondering if I should swap it out as I can not get the new HU I want yet. Parametric on this alpine works nice. My highs are lacking and I think it is the amp, but wanted to ask what luck others had running one of these.

I went to this for the fader and parametric it has, and still can do all my crossovers and gains from driver seat.

The G190 is not a "real" crossover.

Then what is it? I can't turn the amp filters off so they are set beyond it. It seems to work nice except it does not have highside gain and will not turn the sub gain all the way off. I wish I could have compared it, but I rewired everything so I could not. I suppose I could put the nak in there and try it on the fronts/subs. Did compare the high side amp I had before with this one and pretty sure the amp is not up to speed for this system.

If I go and swap amps/wiring/subs like I plan just want to know if I should suspect this g190 as well. I've had plenty of other analog crossovers that sucked, has been a big problem for me. If need be I'll dig up something else to try since I will be into the wiring anyway.

Or do you mean sell stuff and buy a DSP HU already....

What exactly are you trying to use it for?

I run the whole system off it into the kicker 5ch so I can play with it on the road; it has the sub parametric, LP/HP xover, fader, sub level, 15Hz subsonic, and a few high side EQ knobs I never use. My old one had no fader and I need the rears for out of the car use as I can't hear the fronts out of the car. I wanted the subsonic and parametric for the IB subs too and it works awesome compared to not having those features. It does not sound right but I changed too much stuff at once to know what it is. I hoped someone here ran one and knew about them.

I'm po'ed I don't have time to work on it and swap stuff so trying to do my homework for when the time comes. Just had the thought that I don't really know anything about the alpine other than good reviews I read about it.

Your goals are very, very strange. I personally wouldn't put that thing in my car as I see no useful features on it.
