I am a huge fan of Image Dynamics, but this was one set of speakers from them that i did not like at all. And i agree with what you are describing as that is how they sounded to me.
I do not think its your amp...i think its the location of the drivers. Have you tried placing the tweeter and the woofer together and mounting them both in the stock woofer location?
Then once you do that you can also reverse the polarity of one of the tweeters or one of the woofers to see if it helps.
You can also lower the HP to 80hz and be ok, that wont afect your current issue, but it will being your bass up front a little more.
