  • Mounting tweeters on A-Pillars

    I'm looking to mount some tweeters on the A-pillars of a 2003 Accent. I've done sail panels before with fiberglass and I've had trouble with the fiberglass not sticking to the sail panel at all. So I've got some questions.

    What are the cleanest ways to do an A-pillar? How feasible is it to use something like the ABS with Acetone mixture I hear about on here. Then after I do that.. sanding it down and painting the A-pillar? How would I achieve the OEM texture if I did it this way?

    I know some people just use a cloth covering for the A-pillar once they're done. this doesn't look too factory to me but I suppose it could be an idea. Whats thoughts on this method? How would I get the cloth to adhere tightly to the A-pillar on the back of it?

    Basically I'm wanting to keep this install as stealth as possible. I've got the amp and sub mounted infinite baffle under the rear deck and have factory matched carpet on that so it's hardly noticeable. The midwoofers are going in the factory door locations. So now I just need to figure a way to get these tweets in discreetly. Does anybody have any suggestions as for other stealth locations? I had considered mounting in the defrost vents even but they are really really small on this car. Any advice appreciated. Thanks, Arit.

    Have you looked into whether or not your model came with an upgraded stereo option?

    High model levels might have a pillar speakers or sail panel mounted speakers.

    The solution may already be out there, it was for mine.

      That's a worthy idea. Where and how would you recommend searching for such a part. I tried google for a bit but couldn't seem to produce anything useful. Thanks, Arit.

        Try to find a forum for your vehicle and ask the question there.

        Probably get the quickest results that way if google isn't helping......

          I've seen some guy fashion a circular template (slightly larger than the mounting hole for his tweeter) and use that to flatten a portion in his a-pillar using a heat gun

            I would use that plastic weld that comes in a 2 part mixture, you can find it at autozone or peps boys, etc. It seems like molding in a lilliput bezel went pretty easy that way, I don't see why it won't work with tweeters if you have plastic tweeter housings. When i did my tweeters I just cut the holes so the tweeters were friction fit and just bondoed around it.

              ABS would work if your a-pillars are also abs, if they are PVC or PP, or anything else, It wont bond and you'll have separation issues.

              My car has them from factory, so I personally haven't done this, but I've seen some people getting ABS pipe from the Depot that is the diameter of the outside of the tweeter, wrapping the whole thing in Fiberglass and cutting the tweeter hole. Also I've seen plenty of abs used for making panels. (Stronger than fiberglass...) It can be thermoformed, or filled using the magic mix.

              Home depot also carries a product that has the ABS and MEK already mixed, it's called "Oatey Black ABS Cement" Goes for a couple bucks, and saves you the time of shaving abs and waiting for it to dissolve...

                Mount them to the dash facing your windshield. The glass will bounce the signal at about a 90 degree angle right at your face/ears.

                  if you do that bounce you have to also wire them out of phase but that is going to be cause problems in tuning. you should try them in different possitions before you start fabricating.

                  another option is to aim the tweeters at each other if your tweets have good off axis response.

                    Why would you wire them out of phase? A 90 degree deflection will not cause any noise cancellation, especially in the tweeter at a 17k - 22k frequency range as far as I know.

                    I agree to place them around various parts of your ride to see which location give you the best imaging.

                      Well, I decided to keep it simple. I just pulled out the a pillars, stripped the tweeters of their various mounting hardware until I was just left with the little driver.. cut a hole exactly that size in the lower part of the a pillar, then I painted the tweeter grilles to match the a pillars exactly and just hot glued them in. It actually worked out really great! It looks very low key and very oem. I will get pictures if I can, It was actually my girlfriends car so I don't have the car around at the moment.
