Speaker Problems: Kenwood Excellon Components

I just got some kenwood excellon components installed in my car (KFC-Xr61P). They're the dual mag lightweight, low Wattage ones right? So I'm running 27W RMS to them (60W peak) and they're specs say 8-45W RMS and 180W peak.

I'm having 2 problems with them though:

1) the deeper bass notes distort like mad (we're talkin astronomically more than my stock speakers did). I can't have these things anwhere beyond soft-'I'm talking to somebody in the car while I listen to my music' volume. WTF, that sucks... you know given they were friggin $300

2) the trebble is off-the-wall loud... I have the tweeters set to -4 dB on the crossover (max drop) and all frequencies above 3.6kHz down 12bB on my equalizer. Even with that, if I crank my speakers (of course if I do that I have my bass crossover at 200Hz witha nice soft slope so bass doesn't really happen until like 360Hz and even at that I have everything under 600Hz turned down:thefinger:) the trebble is ear-piercing loud. It bothers me (but I'm used to it to some extent [ anyone ever been in/ owned an MR2? yea... 4" by your ear = hella trebble all the time]) but everyone else in the car freaks out b.c it hurts their ears...

Something has to be wrong. I've read numerous reviews from consumers raving about how good these are and they were able to run them off their deck and they sounded amazing, yada yada yada...

Any suggestions?

what amp you have pushing them?

Internal on the Alpine... ran the 10 ga wire to the deck and all...

stats on that are 27rms 60 peak (per channel) as listed above...
