Thanks Jayw13702. Will check the boot area at the weekend - its gotta be there somewhere - then I need to workout if the output is tweakable! I suspect not but worth a look before I research a new amp. Oh and no I never owned a 156 but the Alfa was so much fun to drive, totally different beast to the Lexus although the Lexus is so comfortable and easy to drive which I kinda like (getting old - lol). Not enough experience yet to comment on changing the 8 speaker system but worth researching if you have the cash and inclination to to it yourself.

Hi. I too have carried out this (really easy) speaker mod and replaced with some very nice Audison 4" coax speakers. My issue is that the whilst the tweeter is crisp and clear the 4" cone seems to hardly move at all or give out much sound. I am working on the theory that there is a crossover (in the amp I assume) and this filters out all but the hi end frequencies down the wires to the these front speakers which are (to be fair) installed as tweeters. Twozero3 - is this your experience and if not can anyone advise 1. Why my 4" cone is quite unresponsive? 2. If I want to check or change the amp in my is300h where the dickens is it. Spent the past week trying to find it or find a post/video/diagram that explains where its located. Tearing my hair out! Any help much appreciated (ex Alfa GT owner until last weekend lol) Martin
