Just bought my 3rd BA Falcon and got one without premium sound/colour screen but has an aftermarket Headunit (kdc-X7100DAB) and wires for a sub in the boot. But no tweeters in the A pillars and the front speakers sound WEAK compared to my old premium sound Falcon. What do I need to do to get properly good speakers, I've heard the 5 x 7 size isn't amazing but want to know what size I can go to and how to get it to fit (no rattles too). I assume I'd need a new AMP? What sort should I be looking for and how do I install or replace it? And Tweeters is it worth buying A pillars with the speaker grilles and putting in tweeters? How would I wire in the tweeters since it isn't premium sound. And Finally do I put a sub in the parcel shelf or the boot?
Sorry for all the questions but want to do this properly
