I've just recently upgraded my factory system in my 05 Accord by adding the following components:
6.5 Infinity 6112i (front door)
6x9 DKC169 MB Quart (rear deck)
US Acoustics USB4065 4 channel amp
I left my factory HU in place and used a lineout converter (Scosche FAI-3) to interface with my speakers. I've played with the builtin crossover on the amp and am still getting drowned out by highs, particularly from my Quarts. So, I'm going to sell my Quarts and go with something a little more smooth when it comes to the highs and I would like to know what speaker recommendations, 6x9's, that I should add to even out everything. Please keep in mind that I'm not going to add a sub (I want to keep everything very simple and I need my trunk space) as well as keeping the cost factor to something a little more middle of the road. I'm strictly interested in SQL and want that factory look, so as to keep people from stealing my stuff.
Thanks in advance!

First off, there is no such thing as "SQL". SQ, yes. SPL, yes. You can't do both effectively anywhere above 50 to 75Hz, and even LESS effectively below that.
Secondly, I like the Boston stuff. I also like the Eclipse Point-Source 6 bys, but they can sound a little bit sterile, too. The newer ones are MUCH more tame in the highs, than the older ones were, but still...
Your built-in crossover isn't going to affect the highs one little bit. If your deck has EQ functions, play with those, or even with the tone controls.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."
