Has anyone identified aftermarket tweeters that fit in the OE locations? I haven't removed the "A" pillar panels (not sure how) and don't know what the OE tweeter dimensions and cone diameter are. If anyone has that info, I'd be interested in learning it.
there's a pretty good amount of room behind it. i havent installed new speakers yet, but i have taken off the a-pillar piece and its pretty open, especially if you cut out the plastic grill piece
Thanks for your input, Dude ! I found that after attacking all four doors with damping material, the OE tweeters were actually fine. No need to fritz with their crossover frequency. The problem I was hearing was due to panel resonances !
I bought alpine component speakers before determining the size of the tweeter. The alpine 6.5 components come with a 2 inch tweeter. It doesnt fit flushly, but I made it fit behind the cover and they sound fine without being flush. One day Ill get in there and figure a way to flush mount them.....maybe.
i have an 08 xb2 and just installed amp and front door components the alpine type R the better set and the best alpine type r two ways in the back door and the front door speakers are a breeze just disassemble your factory tweeter it just unclips from the panel and disassemble the new tweeter and it will pop or clip right into the factory mount
But, Peepaw,, Doesnt the alpine components type R come with a 2 inch tweeter? Mine definately didnt fit flush where the stock one did. Its in there, but not flush.
just twist the tweeter grill on the alpine and it will come right off then it will look like the factory tweeter and just pop it in the factory mounting location like factory looks factory sounds great
