HI Guy, 1st post.. I have a BMW e60, and looking to upgrade the speakers - just not sure what amp to get and not decided on speaker models... My Setup will be something like: Front Door speakers + tweeters – thinking Focal though unsure which one - any recommendations? Under Front Seats – Kicker SWS-8 Sub, though unsure if it should be 2ohm or 4ohm, Anyone? I have been told I need a JL CleanSweep to integrate the amp into i drive? What Amp do you recommend? I will install a Sub in the boot - but this will be at a later date. Also side note: I may decide to just install the unseat kicker subs and do the rest at a later date. So question is can anyone help with the questions in the bullets above? Thanks ps: i am reading this long post: http://www.tyresmoke.net/forum/topic/108127-audio-upgrade-in-e60-535d/ hoping for some answers around my questions too..
