yeah i had the factory McIntosh 4 ways which i found pretty p1ss p00r so replaced them with the DDC6.5s in my signature. also had the front doors deadened both inner and outer skins which helps with the mid-bass. although since then i have grown to dislike the DDC tweeters, they are a bit "bright" for my liking, so i am waiting on delivery of some CDT tweeters and x-overs which i am hoping won't make my eyes bleed.
my parents have a mazda6 with the bose system, and yeah, they aren't a bad OEM stereo. the 6 has an 8'' IB sub in the parcel shelf like the libs with the mcintosh system. i'm still deciding what sub i am going to replace the factory one with in my lib, but i am thinking of the Vibe exact8 which are a great sounding sub that can be run IB.
what h/u, amps etc are you running???
if you are definitely after an underseat sub apparently the invisabass (i think that's what they are called, maybe double check with the MEA guys/girls) unit isn't too bad for what it is. aaaaaalthough, i am trying to offload some of my gear that's sitting in cupboards etc that won't be going into the lib if you need amps or i have 2x jl audio 12w3v2's for sale as well. a mate of mine may be buying them, he is just trying to clear it with his wife so i may close the topic if his wife lets him buy it.
