dyn 7" 3 ways run by audiosystem f2 500 and eclipse cd7100 HU thats what i've got so far but i also have a alpine type s sub and some american brand amp powering that. when i come back to modding my stereo i will be replacing that with a id max 12 and another f2 500 to run that. or i might cut the bass cheaper and get i id q and a f2 250. see how i go. bass isn't very important to overall sq. just been modding my sussy lately next brakes then stereo again. it goes really well now so there is no rush to change.
