before i ask my question, i'll tell you my current setup.
stock HU/AMP...all infinity refrence speakers. (front componants/rear 3way6x9) 4 ch amp pushing main and mono amp pushing sub. so, two amps intergrated to stock amp with 2 LLCs.

so 2 LLCs for a six channel amp? that means i had to do away with two channels.
i connected the LLCs to the front woofer outs and rear speaker outs, disconnecting the front tweeter out.

now, the front speakers have hecka bass and hardly trebble even with the crossovers and the rear speakers are ALL trebble with no rumble. the speakers i have are soppose to be decent, so i'm guessing i'm doing something wrong.

the sub is fine. i got it in line from the front channel LLC. so all bass.

i'm talking lacking to extremes. i have adjustments on my amps, but it dosen't turn up the trebble or bass enouff and if i adjust the settings from the head unit, one set of speakers would get blasted with the enhancement.

does anyone know if the front tweeter line from the stock amp is full frequency or is the rear speaker out full frequency? any input? it's weird but no feedback in current setup at all, but if i mess with the LLCs and just use one set of channels (front channels) for all the main speakers and the rear channels for the sub, i get MAD engine feedback. okay...i hope someone can help.
is there a way to combine the stock front woofer and tweeter outs? pics....

i know people are gonna say i should change my HU, but i like the way it looks. there's no feedback and i got the CD changer. really nothing else i need. i'd like to keep the factory look for a while.

I hope this will help.
I'm guessing you have a Pioneer Deck no NAV 98-02 GS?
I have a very similar setup.
You have several problems.

No Highs or lows.
My installer tried everything. you have to use the LLC after the stock amp behind the glovebox. this is where you get the full range. In my case we ran the LLC from the front of the car in case I did want a HU later.(no need to run more RCA)
I used a total of 3 LLC because it is a 5 chanel amp. I hope you can find a diagram pic of the system. I'm sure someone can repost it.
I don't have it anymore.

MAD engine noise.
BAD Ground. Keep it short and at least same gage as your power.
Keep one spot on bare metal where everything grounds.
The bolts underneath the carpet are good.
turn down the gain on the LLC or the Amp.
