J Audio xd600/6v2 and JL Audio 600/1v2 crossover settings

Hi everyone,
first off I have a 335i e93 with HIFI. I finally had my system installed. I am not happy with the sound. I would like to know where to set the crossovers and gains on the amps. My system consists of a JL Audio xd600/6v2 running 4" Helix Match components in front doors on ch.1/2 ......OEM components in rear on ch.3/4......Eartquake SWS8xi 2ohm. 8" subs under the front seats on ch.5/6 ( Technic Harness) ..... In trunk I have a sealed 10" Kicker COMP RT 4 ohm. box driven by a jl audio XD600/1v2......Until I replace the under seat Earthquake subs with Jehnerts how should I adjust the crossover and gains on these amps to get the best possible sound?
Thanks, Genna

Showing a picture of your amp setting or listing them

Showing a picture of your amp setting or listing them might be a good thing to
do.
A frequency of around 200 to 180 is good for most speaker combo's as
a starting point with hardly any gain on the front doors and none on the
rears and about 10 or 11 o-clock on the underseat gain is and average setting.
If you bought the 2 ohm underseats the gain might be less.
Do you have the high pass and low pass switches in the right position.
You need someone with SWS to chime in on this.

Also were there any setting on the door crossover between the tweeters
and 4 inchers.

If you are going to adjust stuff mark where you started from so you can get
back to it by putting some masking tape and hash marks on it.

Thanks for the advice. I would upload pics of my amps but I can't figure out how to do it on here yet. To answer your question as to what the crossovers are set at, I really don't know. I'll have to call my installer and ask him. I feel that the tweeters aren't bright enough though.

The crossovers for the tweeters genraly are adjustable

The crossovers for the tweeters generally are adjustable
via jumpers but the setting are limited. Does the installer
have expierence with these cars?
Go to the advanced setting on your pc and select the photo you
want and download it.

I guess the match crossover has no adjustment upon looking more closely .
