    DIY: Tweeters

    Yo, I've been working on these the last few weeks and finally got them fine enough to stop fussing over. For now.

    For those of you who want to improve your ride's sound, this costs about 30 bux and a few dedicated hours.

    You'll need:
    Screwdriver's to get your door apart.
    A dremel or cutting bit.
    Two tweeters.
    A soldering iron and solder.
    Extra wire, to connect everything with.
    Electrical tape or shrink wrap, to keep the wires separated and clean.
    Possibly some resistors, depending on the power of your amp and rating of the Tweeters. Read the box.
    Bondo.
    Sand paper. (up to 400 grit minimum)
    Paint and masking tape.


    Before we begin, I'd like to say that this was my first venture into tweeters and bondo. I don't mean together, I mean for each. The tweeters significantly improved my audio, but I learned that bondo is a royal pain in the butt. I also learned to always take the sails out when working on them. Don't be lazy and apply bondo or anything else while they are still in the door. It's just more work in the long run.



    Alright, first of all, take apart your doors. That should be pretty obvious. You can always get some spare sails if you want to do those first, but this is how I did it.

    The guy at the local audio shop recommended this brand from his selection. All I can say for these is that I love them. I put them nearly flush with the sail, no angles, and they sound pretty centered, sometimes even like I'm wearing surround sound headphones.





    You should know how to get your door open by now.



    I don't know if the foam served any real purpose, but I took it out.



    Drill a pilot hole. I'd highly recommend that you take your time while making the holes, and make sure that the tweeters are exactly the same. Using some tape to make guides is a good idea.




    Post-dremel.



    The power mirrors never worked on my car and I never adjust them, so I just cut the wires out. They were only in the way.




    Ok, we've taken our time and drilled/sanded out the hole. In my case, I had a dremel with a sanding wheel on it, which sliced through this like a hot knife through frozen butter.




    Hopefully you've got your soldering iron nice and hot by now. A personal innovation I'd recommend is that if you use these regularly (like me), a 3 ring binder makes a great carrier/stand for them, like here.







    Note: If you need to wire a resistor in, make sure that you get it in here. You don't want too much power going to your tweeters after you have them bondo'd in and everything, that would be a lot of work to replace. In my case, my header puts out 16 watts rms, so I'm pretty safe.



    Also, I know it's not the prettiest soldering job. It just gets uglier as I redo it while working on it, too.








    Ok, I took the opportunity to clean up my previous speaker install job. I soldered those puppies up, then added the tweeter cables to them and screwed em back in.




    Wrapping electrical tape around it.

    Continued.







    I was pretty happy with these as they were, but I figured I might as well make them look good while I'm at it. I was also worried that someone might start playing with them and pop them in, so I'd have to open the doors up again and fight with them.


    I'd also like to note that at this time, I was setting up for my subwoofers. I finally got those going and put the tweeters on hold for a week and a half while dealing with some problems.


    Back to the tweeters. When you have them set up how you want them and you're ready to bondo them, it's wise to put either some bondo or JB Weld (what I had on hand) on the inside, to help keep them in place. Doesn't need to be pretty, just keep them from moving around (and cracking the bondo when sanding).

    This was after I finally got back to them. Here you can see the second layer of bondo.




    I personally would HIGHLY recommend that you sand by hand at this point. The dremel was great for cutting through the thick stuff, but if you learn how to do it right, you don't have big thick piles of it anywhere. Just smooth it down and get rid of what you don't need on there, then sit down for a half hour and sand them down. You'll thank me when you don't have a bunch of dremel marks when painting.

    To clarify, you don't need to glob a lot on like I was doing then. I'd recommend doing it, but then taking something hard and flat and scraping off the excess, so that you have a flat, air-bubble-less area to work with.



    Bondo is a blessing and a curse.




    After LOTS and LOTS of sanding,



    You probably can't tell in that picture, but they are uneven. The right side one (which is the driver side door) is almost flush with the sail, where as the passenger side one has a niiiice curve to it. That's another result of me rushing it at first. DON'T RUSH IT!


    When painting with spray paint, do lots of little coats. I personally haven't quite mastered spray paint, but with enough work and sand paper they came out alright. I've had someone comment on them looking factory.







    They aren't perfect, but they look better than they originally did, and they still sound great, even after spray painting them to hell.
    You can see a little pink around the grille on there because when I first did the bondo, I didn't bother with masking tape, cause I was stupid and wanted to waste a morning before work.

    If you choose to try this yourself, best of luck! You will probably want to play around with different positioning before you make the holes or take it too far, so give it some time and see what works best. Taking your time is key to quality.

      And a quickie on subs.

      This is a small add on to the tweeters, these are the subs that I ended up setting up.

      If this is the first time setting up subs, then you'll need to run some RCA cables through your car. Choose a side for the power, and a side for the signal. They don't work well together.

      I ran my signal cable through the right side, under the carpet, and the power and remote wires through the left side.

      These are the RCA cables (in the tangle of other wires) that I originally had in the car. I swapped them out for something a bit nicer when I redid the system.




      The remote wire simply runs from the head unit to the power antenna/subwoofer amp. It lets the components know that they are needed, so that they can power on and not waste power while your car is off.



      You'll want to run a thick power cable from the positive terminal on your battery to the Power terminal on the amp. It's best to have your battery unplugged while doing this.

      Check your manual for the amp. For my Visonik amp, it wanted a 50 amp fuse in the line. For my Xplod, 60 amps. If you can't do what they have, it's safest to go below, else risk blowing your amp.



      You'll need to find a hole somewhere in the firewall. I used a screwdriver to poke a hole through one of the rubber grommets. Just be careful and don't break any wires, else your car might need some serious re-wiring!




      This is my final amp/sub/wiring.





      The big brown wire on the right is the ground. It's wired to a sanded down part of the chassis, near the antenna. The red is the power, as shown before. The tiny cable next to that is the remote (the 12 volt wire from the header). Wire up your subs + to + and - to -.
      If you have a single channel amp going to two woofers, or any different combination than 1 channel per woofer, find out if your amp can deal with different ohm combination. It's a bit of math I'm not going to go into here.

      Supposing everything is wired right, next time you start your stereo up you'll have some new shaking windows!

        good trick for the soldering iron,

        glad you went back and filled those gaps.

        Little more polishing and maybe some paint...but good work

        I just realized I LOVE wiring...I don't know why. Good job!

          There is a different hole you could've used to route the power wire. It's located behind your intake on the firewall.

          The hole is right above your ECU. Just a note to make your engine bay appear "cleaner".

          Less mess is always a good thing.

            I'll look for that next time I have the hood open, thanks. I looked around for about 5 minutes but that was the only opening I could see at the time, so it's defiantly worth a shot, even if I have to re-run everything.

              great diy . nice job on the bondo . personally i wouldve placed the tweeters in the doorpanel so itll sit flush and theres not too much space between the tweeters and the woofer. i read somewhere that they should be as close as possible in order to get the best sound. i like how urs came out though

              the hole on the firewall is near the engine bay fuse box. i couldnt find it at first but if you go in ur passenger seat and pull back the carpet a little ull see the hole (it mite have a plug, just pop it out). i stuck a wire hanger and ran my cables threw there.

              alone in this game . ::My Ride My Way::

                Sweet write up. Made simple. Anyone should be able to tackle this.

                Glad to see you finally got enough posts to make it. Congrats!

                  Another note on tweeters. If you don't buy tweeters with a built in high pass filter, you'll want to add a capacitor to them. It's not power that blows tweeters, it's lower frequencies. The resistors only limit power, but you have tweeters with a cap soldered on a circuit board so you're good.

                  But nice write up. I'm going to angle my tweeters about 45 deg so I guess I'll make like a continuation from this in another thread.

                    I forgot about that. The boss tweeters that I got had built in high pass filters, as well as were rated for 45 degrees (I didn't understand what that meant until I started playing around with them).

                    Let me know when you do, I'll link to it.

                      Amen. Like I've always said, it's not power that destroys speakers it's distortion.

                          Wasn't on these, in my case. I've seen some fancy ones where you can do that, but living in the middle of nowhere, it was a small audio shop or Walmart. I went with the audio shop's best for 20 dollars.

                          If you can, definitely remove the tweeters from their housing. I got bondo on my grilles and I had to work that out and repaint those in the end.

                            would you happen to know a good hiding spot in the door panel to hide some crossovers?
