Stereo separation network at the amp output – TDA7388

.
Indigent Audio, yes I think I’ve researched enough to know how hard it is to even ‘remotely’ get close to HiFi in a car, let alone doing so on a limited budget. But when it’s the system you’re gonna listen to everyday you’ve gotta squeeze every drop of capability out of that. DIY’ers and tweakers are familiar with the feeling!

So you advise me not to touch the “rearfill” issue? Oh you’re not discouraging me to give up on my car completely do you?
What do you suggest as a major upgrade to stereo imaging or other aspects of sound quality? I already have Bi-amping in my program, which is a solid upgrade and consists of 4ch class AB driving mids and highs, and 6ch class D driving woofers and subs. I’ve also got this idea of modding the placement of mids and tweeters to achieve best frequency response and, hopefully, balanced level between left and right. Then I’m gonna add some basic functions using my head unit, like basic EQ and time alignment. Oh, and I’m gonna fire my subs and 6×9’s back to the trunk to get a nice infinite baffle, tight and deep bass from relatively cheap speakers.

Just so you know how far I am from a true SQ system, you should know that I’ve got 6×9’s in the rear deck!
This is the best I could do to get the maximum sound level (just so that I don’t deal with the non-linearities of the overpowered drivers or any annoying thing like that). To be specefic, Pioneer 6990F’s in the back and Pioneer 1680’s in the front door. A pair of 8 inch subs. 12 sqm of damping mat. JVC 462BT head unit, a 6×100W class-D homemade amp +homemade crossovers is all I got for my car. Not really fancy nor top-notch, but if I can squeeze the quality out of it, that’ll do just fine for me.
.
So any ideas? I’m still looking for my stereo separation tho!
