Many moons ago i was in to car audio in a big way and my car at the time was dynamatted, and full of MDF and Carpet trim stuck down with spray glue with huge fuse boxes and all sorts of **** everywhere. These days i prefer to spend money on my home entertainment, but every so often the speakers in my A3 let me down. I run a dension ice link+ for my iPod through the standard HU but probably listen to the radio 70% of the time, so i only really crank up the volume for embarressing sing along moments... I just want to replace the speakers with better quality ones, the OE ones are sort of OK but 8 years of use has had it's toll on their flimsy cones by the sound of it. These guys sell adaptor for fitting 13cm to the front and 17cms to the rear: http://www.caraudiodirect.co.uk/aud...7.html?cadid=cd8b42a662c6b0be67ce15c059ff77c2 I'm pretty sure that's bigger than OE, will they fit with no other mods apart from the adaptor? I think the rears are just 2-way but the fronts have a tweater too, is there an OE crossover or are the tweaters run straight from the HU? If so, is there a 13cm mid/1" tweet (i think the OE tweets are 1"?) component combo that'll fit, this one perhaps? http://www.caraudiodirect.co.uk/inf...8.html?cadid=cd8b42a662c6b0be67ce15c059ff77c2 Or won't that run straight from the HU?... I'm not fitting an amp, but don't want to fit speakers that the HU simply can't power. Also is there plenty of space behind the doorcard to tuck a crossover? Finally, that 'sub' thingy in the rear wheel arch... Anything that can be done with that or utilises its location... I'm not fitting a boxed sub.
