Sorry to bring this up again, but searching didn't really reveal any answers for me.
I've just bought an adaptor kit to fit a standard head unit, but although the kit looks well made on the surface, when I tried to put it together I had several problems.
First, the attachment of the lower 'pocket' to the front of the surround is rubbish - the bits where the screws go in are semi circular so hardly grip at all - the pocket just fell off again when I was putting the cage in.
Second, there is hardly any material for the cage tabs to engage with - the top part is so thin that none of the tabs worked - this is a standard Pioneer cage with plenty of tabs too. The sides of the surround are the opposite - too much material so that none of the tabs can even be bent.
Lastly the gap for the cage itself is too big - there is a gap of about 1-2 mm above the cage.
Has anybody else had these sort of problems? From looking on eBay and the links people of posted on here, the kits all look like they come from the same supplier, so I'm worried they are all the same.
I was really disappointed because I wanted to get the new head unit fitted last night, and it felt like I was assembling some really poor quality parts. I would be ashamed to put them in the car - I could just imaging the whole lot rattling and squeaking away, when the rest of the car is so well put together it's almost silent!
