I am budgeting $2000 on just mids/Highs. Now I know that there is plenty of 6.5"s and 8" on market to get my mids and highs sounding pretty damn good for $2000. I listen to everything from country to rap to hard rock. I want loud enough so that People will know I have something when I drive by.
Thank you for providing this additional information, as it is very helpful. What I recommend below will definitely provide outstanding audio quality, and "People will know I have something when I drive by".
If you are budgeting $2000 for the 4 mid/high speaker sets, then I strongly recommend that you consider and listen to Focal speakers. IMO, they are about the best for non-competition quality speakers on the market (and they are even used for competition at higher price points). They are specifically made for mid/high sounds (from 80 Hz and up), as 90% of audible sound comes out of the midrange frequency spectrum, and they will tell you that you HAVE to have a sub-woofer in your speaker system for full sound preproduction. They range in prices from $400 per set to $24,000 per set.
I installed a Focal speaker price point of $600 per set ($1200 for all 4 doors and posts), 9 years ago in my Honda Fit, and when I bought a new Honda Fit, I had them moved into the new one. Today, they are in just as great a shape as they were when I purchased them. They come with a true analog filter system that has options for 3 different transition frequencies for the mid to high sounds, and there are 3 different relative high to mid frequency relative volume options. Bottom line, they can be tuned to provide the best overall sound for your vehicle (this is needed, as vehicles and the driver position make for one of the worst natural acoustical environments that you can have). I would have bought Focal subwoofers, as well, but they were out of my price range.
For an amplifier, I installed a JL Audio HD900/5 five channel amp (four 100 RMS watts per channel amps and one 500 RMS watts amp) for $1500. The amp is small in size (11" x8" x 2"), and it has all the wiring options that you will ever need. I can play at high volume, and the amp never gets hotter than luke warm. I guarantee you that the 500 RMS watts from this amp for the subs will blow away your Kenwood KAC 1000W mono amp.
For subwoofers, I installed two 10" AudioMobile GTS 2110 subs $300 each in a custom sealed enclosure. A sealed enclosure is not as loud as a ported enclosure, but the sound quality is far better. And the volume out of this dual sub sealed enclosure driven by 500 RMS watts is more than loud enough to give me a headache within minutes, if I turn it up too loud. The AudioMobile sub is an American made sub that has a standard speaker shell design, and not a pancake sub design. However, these AudioMobile speakers are specifically designed to be installed in small sealed enclosures, requiring only 1 cu. ft. of internal volume per sub. These AudioMobile subs have the sound quality of JL Audio W3 subs, but are 30% cheaper.
