What loudspeakers to use in front?

What loudspeakers do you recommand to use in the front? Must fit in the original covers as I dont want to ruin them. Thanks

For which of your BMW's you need speakers? The whale ('85) can be set up with bigger speakers than the shark ('80)

Within this link you will find 4"x 6" speakers. You should take one with the 90 or 91 db sensitivity. Also take into account the mounting depth, for the whale the Polk compo will be good. the JBL might fit the shark, but i am not completely sure about the mounting depth

Thanks a lot for your reply and link! It's for the whale, the shark is a looong time project. The dept of the "sharkspeaker" is 35mm I think. I will send an email and check out of they ship to Norway
