balanced sound for two rows of seats, front and back (third row optional)

You can't physically have a "sweet spot" on all possible seating position at the same time.

Anyway, the quick fix for middle-row sound quality is to replace the OEM speakers to coax. Optionally, you can install seps and have the tweeter mounted on the B-pillar (as long as it doesn't interfere with the front passenger seat belts) or stick it anywhere forward of the rear passenger doors. This should help with the production of a more complete spectrum of sounds and nuances.

As for balance, to hear the proper stereo imaging or sound stage, there are actually two major contributing parameters here.... channel volume and delay. The balance knob can stand in as channel volume. But for the sound to be "really" balanced to our ears, a delay must be introduced to the nearest speaker in relation to where you're sitting. When you're on the driver's seat, you want to add some delay to the front Left speaker so that sounds from both Left and Right speakers arrive at your ears at the same time. When you've dialed this down properly, this would typically put the stereo center in the middle of your dashboard (but only to the person sitting in the driver's seat).

If you're the front right passenger, the delay and balance setting should be reversed (ie. Increase left channel volume and introduce delay on the right channel). That way, your perceived sound stage would still appear to be smack in the middle of the dashboard.

Some add appropriate delays to both speakers (mine included) to trick our brain and make the sound stage seem further forward (ie. the band may sound like they're playing from the center of your hood), as opposed them playing in-your-face. The former makes for a more pleasant listening, IMO.

But I digress... Changing out the rear speakers to include a tweeter would help tremendously on the sound quality. And if you really want to keep your OEM HU, you can only play with the balance and fader controls, which is acceptable, but not ideal.

Thanks for the inputs...

Seems co-ax is the way... but I have always thought the stock speakers are already Co-ax (sa rear)... meron pa pala na hindi ... at least no new mounting holes needed

My hesitation with the 2 way separates, is where to mount the tweeters w/o punching any holes.

Thanks again, this will firm up my simple decision

Kailangan talaga palitan yung headunit kasi AVT units tend to "weaken" the volume kapag nasa likod kahit paglaruan yung fader.
