....I just finished up installing a pair if Infinity Kappa 62.5i's in the doors. Only ran into one problem (there always has to be one)....I stripped the bolts that hold the passenger door handle on....need to go out and get some new bolts. Other than that. everything went smoothly. I just positioned the tweeters (you can rotate them for the best angle) and put the stock speaker grills back on.....off to Home Depot for some bolts.

I'll post a couple pics.

Door apart

Crappy stock speaker

New speaker installed using old speaker as the spacer

All done!

One thing I did notice is that the new speakers sit *extremely* close to the door panel and stock speaker grill....no room for error, that's for sure.

Can you describe how you used the stock speakers as your spacers for the new speakers? Thanks.

Sure...I'll try as best I can. Once you remove the stock speaker from the door, you simply peel the cone of the speaker away from the plastic frame. Then, turn the speaker over and with either a dremel, or a pair of plier snips (I couldn't find my dremel) simply cut away the plastic that holds the magnet to the frame of the speaker. What you're left with is the shell of the original speaker that is perfect for use as a spacer for your new speaker. Simply attach, with screws (more than likely the ones supplied with your new speakers), your new speaker to the spacer and then mount it back in the door. There's a hole in the top of the spacer where the original speaker wires plugged into the speaker....if your new speaker has a crossover, you can use that hole to run your wires through....works perfectly.

so hows the sound now? better highs or lows? im assuming everything eles is stock..head unit?

The sound is MUCH better. You can see my H/U install in this thread here.

The speakers behind the seat are still stock, but I'm going to replace them with another pair of the same Kappa's. I disconnected the factory tweeters because they were too harsh sounding and they were ruining my sound stage.

Definitely a much better overall sound. The highs are more defined and clear, while the bass has a lot more tone to it and you can crack it without worrying about distortion.

Man, I knew Bose speakers were crap but one look at that driver reinforced that theory. A good 'ol paper cone with a "whizzer" attachment. That's 1960's technology for ya!

I didn't have the BOSE system....those were Clarion.

At least they don't charge high prices for "their" crap.;)

I hate Bose with a passion.:icon6:

About door panels...do they have clips? I was at my dealer last week, going to get a couple spares for the weekend of the 4th, when I plan on installing mine, went to the parts dept. and couldn't find the on the parts illustration. So..clips, or no?

If by "clips' you're referring to the standadrd plastic fasteners found in all door panles, then yes, they are definitely there.

had the exact same speakers that i was going to install. The rear ones made it in, but i sent back the front pair to get the component version (seperate tweets) now I just need the time to put them in. Did you keep the factory tweets hooked up or you diconnect them, just wondering.....

I disconnected the factory tweeters because they were too harsh sounding, and they were ruining my sound stage. The reason I opted for the coaxials up front was because of imaging. The farther away your tweeter is from your mid bass, the more your sound stage is altered. Not to mention the fact that I have time correction on my Alpine H/U, and the position of the tweeter in the pilar screws that up as well. The coaxials sound AMAZING down there in the doors.....you'd honestly think there's speakers up in the factory tweeter location, because you can angle the tweeter of the Kappa's.

I should have asked this earlier, but with my crossover it comes with a 0db and -3db placement for the tweeters, did yours have this? If so which did you use?
