Hello I have a Toyota Verso 2010 1.6 basic equipment with speakers front (not rear) in the door and in the corners under the front window. I want to improve my sound system. There is a JBL system from Toyota but that I find with 1225 EUR + mounting a bit too much. I have experienced earlier great improvements with only new speakers. So I want to exchange the speakers front. I found a few other threads on the internet, but although it was as simple as I think that is still a bit complicated. Does someone have heartbeats with this and can explain that more precisely? 1. Do I have to dismantle the whole door covering? or do you just have to expand the speaker rust. How does that work (step by step)? I’m not a professional. Do you need special tools? 2. How with adapter rings? It looks like you have to drill rivets and there are only 3 rivets but in normal speakers there are 4 screw holes so you have to use adapter rings, g ibts die bei Toyota? 3. How are the speakers (tweeters?) removed under the front panel? Do you need special tools for this? 4. Why do you have to install two crossovers? Are there not standard crossovers for the existing series speaker? Where is the crossovers connected and installed? Some write in the doors others under the armature board 5. Are they prepared for rear speakers? I have no speakers in the rear doors (because my model is basic equipment (Denmark) but are the lines still there? And is it even important with speakers at the back? 6. Why not install a 2 way speaker with built-in frekvenzweiche in front door? And then save the expansion of the tweeters in front window? 7. Are the speakers and adapter rings for “Toyoyta Corolla Verso” the same as for “Toyota Verso”? 8. What are the speakers recommended? I found them http://www.powernetshop.at/…/to yata-corolla-verso-speaker.html What do you think? Do you have to think about the deep?
