I know the s2k has 6.5" ...
and according to the infinity kapper 652.7i user manual, it is 165mm which should be 6.5" ... but in many site it said this speaker is actually 6.75" .. or some said oversided 6.5" ..

i have bought these already... anyone knows if these will fit my s2k front speaker?

652.7i? why did you buy those? don't you need speakers that have a separate tweeter and woofer?

 

I grab it off really cheap ... and did not really pay much attention to it ..

so it is not going to work ??? .... obviously ... i am not an expert in audio stuff ...

 

you can probably get a spacer, which will offset it from the door, then you will drill the speaker through the spacer into the door, and the angle will be enough for the magnet to fit into the rest of the door....

BUT

don't you have a tweeter higher up in your door? if you use what you have (the 625.7i), i don't think you'll have as good of a soundstage as you are set up for...thought i think mine are fine with everything in the door panels...

 

... hopefully at least it will fit .... i dropped it off already for an audio place to install ... they will probably let me know tomorrow ...

the only reason i got them is because they are cheap .... i did not pay much attention or do any research ...

hope it will still work ... or at least fit ..with spacer like you said ...

 

with a spacer you should not have any problems...except that you should have a tweeter in another place and you are not going to have one there
