This is a piece that plugs right into my headunit and add's on a lot of features to my headunit. It even have a defeatable 9 band eq..
this is the equalization I am using in my system.
I also have a epicenter and a couple of crossovers that I'm not using right now. AudioControl's 3XS and a 2XS
Here's the list of components in order thru my rcas.
headunit-epicenter-EQH5100-
(the EQH5100 splits into 3 channels)
Front-I have the the front and left split into 2 each and channels 1 and 2 of and A404 are using the lefts and are running my left channel of my component set with a passive x-over. and channels 3 and 4 of my A404 are ising the rights and are running the right channel of my componet set with a passive x-over..
Rear-NOT USING this (no rear fill yet maybe someday)
Subwoofer- this goes to a A600.2 powering my subs.
My question is that could I make use of either the 2XS of the 3XS.
and should I get any other sort of equalization in addition to or instead of my current one which I can defeat or set at 0 for all..
Someone told me I should use a audiocontrol EQL on my front channel in addition to my current set up and sell the 3XS and the 2XS. what should I sell them at and what's a good price on a EQL..?

I know this is a lot of information and you have to have a wide variety of product knowledge. but isn't there anyone out there that could give me a hand and help to explain what my system is lacking in sound quality and if I should get rid of these crossovers or use them... I already have the people to buy them.. prices??

Are you using any crossovers now? I dont know the PPI amps very well, but I didnt' think they had x-overs built in? Basically, all you need is a basic, 2-way crossover, since you've got the component crossovers. Have you had you car RTA'd? If it looks good on the 'scope, and sounds great to you, you shouldnt' need any more EQ. I am of the belief that less is more. I do run a 1/3 octave EQ in my car, however, it is defeated for the SQ portion of judging. I hope this answers your questions.

If it dont fit, force it... if it breaks, it needed to be replaced anyway...

The ppi amps don't have any x-overs built in. I'm not using the 3xs of the 2xs I just have them both in my bedroom from old installs.
I was wondering if the 3xs which is 24dB/Octave and has adjustable Crossover Frequencys would be of any use on my front stage I'd send both my front and rear channels from my electronic EQ (which I think if full range) and it would send out everything from what the midbass on the MB's need on up with a new chip inside just in the front output. and let I'd the passive x-overs filter that range for the tweets and for the mids.
But I do have a built in crossover in my subwoofer output thats on my electronic eq I'm using, I'm also using a epicenter.
The electronic EQ has a high pass settings for around 60, 80, and 120 and thru. and a low pass for 60, 80, 120.
I have it set at 60 for low pass and at 120 for high pass
so that is like band-passing my subs from 60 to 120..?? Nope I've never had it RTAed I will though

or if I get 2 new chips I'd feed a y-d imput in the front and rear imputs on the 3xs so I'd have 2 front imputs on this and I'd get chips for the corrects levels for each part of the component the front for tweets and rear for midrange. and run the front into the front of the A404 and the rear into the rear of the A404.
and each component would get it's own wire directly from the the amp.
wouldn't this only be a 4 Ohm stero load on the is amp. and at the it puts out 50W by 4. not 200W by 2 like I Have it the other way.

Ok, just for kicks... run your front end amp off of the highpass of that PPI amp, and set the highpass to 80Hz, then into your front end amp. Set the low pass on the sub amp to 60Hz. You will have a small gap from 60-80Hz, but this is of little consequence. You didn't mention what brand or size your front speakers are, but, 80Hz should be safe for them to run down to. You should solidify your front stage with this setup, as long as your front speakers can handle the 80Hz cutoff. If you dont need those other crossovers, get rid of them. I dont think, with the crossover built into one of your amps, that you will need them at all. A/C crossovers are goofy, using the resistor packs to change crossover settings. At least with the built in crossover in that amp, you have a little flexibility, without having to run down to you local a/c dealer and hoping they have the resistor pack you want in stock. Get as much out of those x-overs as you can, and invest it in RTA time at a dealer with a linearX or a calibrated a/c meter.

It's not the PPI amps that have the x-over's in them they don't have any..
the crossover that I was talking about was from my elecronic eq (the clarion eqh5100) and that is just the subwoofer output from it. it has the high and low settings so you can bandpass your sub output.

Hey 311. Slow down and read your posts before sending. No rush, they could be a bit clearer. Let me take a guess here.
Your head unit feeds a processor with a front ,a rear and a sub output. Are the front and rear HIGH PASSED and the sub LOW PASSED? This would be like my Kenwood hu.
If yes then run the front outs to your front amp,(or two channels of the 4 channel amp if thats what the 404 is)filtered as low as the mids still sound good at. Then to the passive xovers that go with your mid/tweet set.
Run the rear outs, filtered for 80 hz high pass, to one of the active xovers set low pass 200ish hz then the other amp (or remaining two channels of the 4 ch amp). Then to midbass spkrs.
Run the sub out to the sub amp filtered for 80 hz low pass.
If you have no midbass spkrs then GET SOME, (it is worth it) or forget the separate xovers and the two channels of the amp.
Is this what you had in mind????? just tryin' to help
