Check your room environment. A poor listening room can enhance high frequencies and cancel bass. I experienced some of what you describe and corrected that through treating wall reflection points and room corners with DIY sound panels.

Maybe I should try this- the tweeters are close to the ear, although they are not pointed directly to the ear they are a long way away from the door woofers. I will probably mount them just above the woofers about an inch away.

My plan was also to add a 4X40watt amp, power the 2 fronts, leave the rears out, and bridge the 2 remaining channels to an 8 inch sub and built a small sealed mdf box for it. I have very little room to spare which is why I have to go with the 8 inch, .3 cubic feet I can probably fit in, and I have not heard anything bad about 8's.

I just hope I don't do all this work and spend another half grand and then find this fatiguing is still there

Sounds like you are moving in the right direction...

You may also consider DIY kick panel pods or prefabricated kick panel pods;

The advantage of these kick panel pods is that you do not have to cut up the interior of your vechicle and they will have a stealth look.

Additionally, kick panel pods position the left/right drivers so that they are they are same distance to the driver's ear - thus, the stereo image is retained (as much as possible in the hostile-to-sound quality car invironment).

for the record, it turned out to be phase (thanks Omer!) I somehow wired one of the 6.5's bass ackwards, and after finding and switching them, its now actually pleasant. Still needs an amp and a sub I think, but first I'm going to install cups around the door speakers and damp the front door panels, I get some resonance in the mid frequencies.

That certainly explains the lack of bass, but I thought it was the door mounts - they usually don't have any bass either.

Glad you're happy :D

Just do what I do and lean on the door handle! :lol: :lol:
Had twin isobariks in the back once - the spl was getting hard on the ol' eardrums. :shock: (need an emoticon for shellshocked :lol: )

yep, I agree. get rid of the rear speakers and add even a small sub. Road and wind noise pretty much eliminate any chance of enjoying a finely tuned high freq so tone the tweeters down and beef the bottom up.

The orientation of the tweeters can make a huge diff as well with all of that glass to bounce off of. The highs can real harsh and nasty if most of them are bounced off the windshield and of course it completely destroys what little imaging/sound stage there might be.

I'm still finding it a little awkward to listen to, not painfull like it was, I think it might be the tweeters mounted on the sail panels. I will try mounting them right next to the 6.5's, also I got some cups for the woofers, and have wrapped them in damping material and foam, I will install them as well as damp the door panels- I'll let y'all know if it makes a difference.

That'll help, but you need to add a sub.
