Mach 460 Rear speakers

[newstangman]

My Mach 460 rear speakers on my '04 sound very "flat" as compared to the front speakers/tweeters. I believe the rears are a speaker/tweeter combination, but the treble is very flat. Is this normal???

the tweeters in the speaker rack might be blown and the 6x8's might be the only speakers getting sound

I had the opposite problem....my rear amp shut down and now i got no basss in the back.....the Mach 460 is crap.
