Step 1: Parts Needed

Picture of Parts Needed
1-Clamps.jpg
You will need:
2x Clamps to fit your handle bars (mine were 1 1/4" availiable on line for ~$10 from ebay)
1x Optronics QH-87CD 2 1/2" high performance Halogen driving light kit ($15 at Walmart)
2x 2" mid to full range speakers. Highter the RMS wattage the better.
(Partsexpress Tang Band W2-803SM $32.64)
4x 1" metal washers (Home Depot or Lows ~$2
Small peace of screen door
Wire and switch (can use parts from Halogen kit)
Also you may want
Mini amplifier (Ebay 500w for $18 shipped)
1/8" male phono to stereo rca type cable to plug audio source in to amp.


Step 2: Prepair the speaker housing

Open the Halogen lights and remove the light bulb and assembly. Remove the metal bulb support structure with a pair of plyers. Twisting on them with a little force will break them away. Thread the speaker wire in the opening.

Step 3: Prepare speakers

Using the front cover from the light assemble, trace on the back of the speaker with awl. Use this as a guide so you will know where to cut. Using a rotery cutting tool trim the square speaker to the round shape. Be careful not to cut the speaker itself, just the plastic body. Leave about 3/8" of plastic around the speaker so that it will fit into the light cover.

Step 4: Finish the speaker

With a 2" square peice of screen from a screen window, cut to fit in the light cover. Use a hot glue gun around the edges to hold the screen in.

Step 5: Assemble the speaker

While the Hot Glue is still warm, place the speaker inside the light cover. Connect the speaker wire to the speaker. Insert the speaker, screen, and light cover into the light housing.

Impressive and beatiful. I noticed the speakers are made mostly of plastics and rubbers but are not listed as water proof, do you get much rain where you are at?
Braveit1 (author)  wdsparrow12 months ago
Speakers are not water proof but are still holding up to date. We get rain here but I try not to get the bike wet if possible. No problems when washing either. If there is concern, you can always place ziploc bags over and hold in place with rubber bands.

i had similar idea instead i used pvc end caps. i might do this on lowrider. since it fits the chrome styling

I'm having trouble. The speakers have this terrible hissing noise. Then I open them up and it goes away but then it starts again. Do you think the metal is touching the casing? I never soldered before but I got sound so I guess I did it right but the space is tight betwen the leads from the speakers and the casing. Any suggestions?
Braveit1 (author)  Adinkracom3 years ago
This could be from several things. Your soldering could have a cold short. You might not have heated the solder all the way or hot enough. Also you might have swapped the positive and negative sides of the speaker wires. Also you might be shorting out the wires on the light cases since they are metal. You could cover the joints in heat shrink tubing before you solder them or you can apply a liquid electrical tape over them to make sure they are not grounding out. There should be enough room for all this to fit.
I'm going to desolder and try again. What guage do you recommend?
Adinkracom3 years ago
Any suggestions of how to make the speakers detachable? I have no where I can find to put the amp so I'll put it in my tank bag. Can I use SAE connectors for the speakers or what about a earphone type jack and plug? I'm considerering that it might rain also. Thanks.
Braveit1 (author)  Adinkracom3 years ago
The problem with making them detachable is that it also makes them easier to steal. Radio shack sells all kinds of connectors that should work. Mouser.com has more. As far as the clamps go, you may be able to use thumb screws and a t-nut? Home depot sells those. With a fine screen cover, water doesn't get in the speakers. The ones I chose are also not made of paper so the can withstand a little water. You could also put a plastic zip lock bag with a rubber band over them if they are going to be in the rain for a long time.
I just want the wires to be detachable not the speakers, That would definitely invite theft. I found 3.5 ml plugs and jacks that look like they will work. The jacks are mounted so when the wires are diconnected it'll just be the speakers which I'm going to glue on (Blue strength) I'll post pictures if it works. Thanks for the fast reply. Now I have to wait for the mailman. Bummer.

The mini amps on ebay say the dimesntions are 102X78X31 mm. Is that about 20 inches long? is that for real? I odn't think that would fit under my seat.
Braveit1 (author)  Adinkracom3 years ago
102mm is only about 4 inches long. the measurements you posted convert to 4.02x3.07x1.22 inches. I have no problem fitting that under the seat of my Victory Hammer or Yamaha FZR.

Other UPDATES:
My local Walmart has the QH-87CD lights back in stock but raised the price to $20. They are getting harder to find as the move to LED lighting becomes more popular. The LED replacements are not as deep as the QH-87CD and might not fit the speakers.
I am still riding with mine in place now and it's been aver TWO YEARS!!! They have been in the rain and bright Florida sun. Ride to work almost every day and have no problems with the speakers.
Thanks for the clarification. I'm definitely going to try and make them. Great ible!

Hey...really sweet instructable...I am in the process of creating this system...is there anyway you can make a video of how loud the speakers are?
Braveit1 (author)  glugo3 years ago
They are fairly loud when you are directly behind them. I can hear them while riding without a problem and even better with a full face helmet or windshield. A video wouldn't show much because it is dependent on the quality of the mic on the camcorder and the amp used.

can any one think of where to put a stereo??
Braveit1 (author)  abadfart4 years ago
What kind of motorcycle? What type of stereo? You could wire a small head unit and put it in a tank bag or saddle bag with a steering wheel remote to control it. Sony makes a small marine head unit that would fit a small bag. As I said eariler, get a mp3 player with FM and a bike cell phone holder. Attach the cell phone holder to the handlebars and run wire to an amp under the seat.
ok i found a suitable sound system im going to use a zune that i picked up for $20 it has fm radio and 30 GB of hard drive now i just need help mounting it on my handle bars any ideas
Braveit1 (author)  abadfart4 years ago
Search ebay or amazon for a bicycle or motorcycle cell phone or satellite radio holder. It clamps on the handlebars and holds mp3 players just as well. Usually made of black plastic you can spend a little more for chrome. You could also get the black one and paint it chrome.

i bought myself a cb650 finally and after some creative toying with sketchup i came up with this
bike cluster 2.jpg
Well I don't have one yet but I'm looking at a 1982 Yamaha Maxim XJ550 that they are asking $600 usd
abadfart3 years ago
could you put up a picture of the mounts
Braveit1 (author)  abadfart3 years ago
Which mounts are you refering to? There is already a picture of the handlebar phone holder (in comments) and another picture of the handlebar clamps (Step1). Of the amp, I just placed mine under the seat. It fits snug and doesn't move at all without any hardware. You're bike may be different. This is the one I use for my mp3 player.
i was wanting to know how you fabbed the bar mounts

Do you have the specs on the mini-amp you used?
Braveit1 (author)  Paulb4263 years ago
The amp I use is a cheap 500W mini from ebay. Just search for those keywords. They are about $16 shipped from Hong Kong. There are many different sellers. The one I have has RCA inputs, a wire harness for the outputs and a USB outlet for charging your mp3 player. Sorry no specs.

Do you think you could hear these at ~130MPH on the freeway? I want to blast highway to hell.
Braveit1 (author)  bowmaster4 years ago
That's on my playlist! I don't think you can hear it at 130 on a cruiser without a windscreen and a full face helmet. To much wind. I can hear it at 90 and I don't have a screen.
I have a sport bike (a Kawasaki Ninja 650r) it has a pretty good windscreen and I wear a full helmet. What if on top of the wind noise, there was some police sirens and a helicopter?
Braveit1 (author) 4 years ago
I've had these speakers installed for over a year now and they are still going strong!  Most people don't believe all that sound is coming from the two little speakers.  You can hear them over my Ness pipes.  If you have a windscreen it's even better.  The only thing I would change the the cheap nuts and bolts that come with the lights could be changed out with some stainless steel ones so they don't rust.

I would just like to say I bought the speakers and amp and the sound quality is great. I am looking for the clamps you bought on ebay...what is a keyword to use or an ebay store I can buy them at? I will post a youtube link once complete!
Braveit1 (author)  astyles5 years ago
Search ebay motors for "Chrome 3 peice clamp". They come in different sizes. Get the one for your size handle bars. Mine as 1.25". There are cheaper clamps out there but I liked the look of these. I believe they were made to be used with foot pegs on the bike frame. JP Cycles has them as part number 7000125.

Just went to eBay  and JP's stuff is a little cheaper

Nice Ible. What kind of bike is that?
Braveit1 (author)  ryukyu5 years ago
It is a Victory Hammer.

crazy cool bike!

I have built this system and I am in the process of putting it on the bike.  The question I have for you is where do you put your switch? 
Braveit1 (author)  bnlfan4 years ago
My switch is behind the cover on the left side of the bike near the battery box.  I don't have to remove the cover to turn it on and off.  I have it so it sticks out alittle.  I can tuck it in when needed.  (Held on by magnets.) 
You can get an adapter to put the switch on the handle bars but I don't have a need to turn the amp on and off while ridding.  I bought a wireless switch for my LED's that could just as easily be used for the amp if needed.

very nice instructable dude. made some for myself AND my dad, we both love them XD
Braveit1 (author) 5 years ago
To answer a question posted on another board, Hot Glue guns can melt the glue at two different tempters, Low and High. Low hot glue melts at 250º F while high will melt at 380°F so unless you are traveling through the oven at Hershey's Chocolate factory I wouldn't worry about the glue melting. Small spearkers don't always produce crappy sound. Bass requires the movement of air to get big sound, however bass also requires an enclosed area, something you are not going to get on a motorcycle. So that leaves mid and high range. Truth be told to produce high quality mid an high ranges is not expensive and does not have to be a large speaker. There many high end micro stereo systems with 2" speakers. The problem with the small speakers is that the sound is going to be focused and will not always spread out to fill a large area. Not a problem on a motorcycle because you won't be walking around at all. In fact it works great because the sound will not bother those around you while you are riding. These speakers are quite popular in the do-it-yourself audio groups. The speakers have a Frequency range of 160-20,000 Hz
