Review: 2008 Harley Davidson Sportster 1200 Install! - Quality
product! Sound is awesome for a $60 system, at 40mph and lower
its great. It's plenty loud enough, but as you approach 60 mph
and up truth is no stereo is going to sound like a home
audiophile system. Bottom line is 'buy it'! Customer service is
first rate, they are great! Also, I read some complaints about
bass. When I first connected the speakers they too sounded a bit
flat. I clicked onto my Poweramp music player and set it to large
concert hall and max bass and presto... truly impressive rich
sound! My install - I mounted the speakers on the handlebars just
inside the windshield. Then, ran all the wires and the amp into a
small, front fork mounted, 'tool bag' type pouch. The main issue
is the red hot wire. I must have watched a dozen youtube videos
on this subject. I usually ride with my high beam on. I know its
obnoxious, but down here in Florida anything you can do to stay
visible is a life saver. I unscrewed the chrome cover that holds
the daymaker headlight in place. Sadly, Harley does not provide
an auxiliary wire in the headlight wiring harness of Sportster's.
At least not in mine. There are three wires entering the
headlight assembly from a hole in the back. Black wire is ground,
white wire is High Beam, yellow wire is Low Beam. I used a
plastic splice connector from Home Depot to connect the red Boss
power wire to the white High Beam wire. (AMP Splice Tap
Connectors 10 pack). The hole in the back of the headlight
assembly where Harley runs the headlight wires - Harley runs the
wire harness though the hole with a rubber bushing that protects
the wires and keeps water from getting in. I tried to slice the
rubber bushing so that I could add the Boss red hotwire but it
was cramped quarters and I couldnt get in there without taking
the chance of cutting the headlight wires also. You may be able
to do it, I couldn't. I ran the red power wire through the hole
and at the point where it touched the metal headlight housing I
covered the wire with an extra couple of layers of electrical
tape to protect it from the housing wearing through the
insulation and shorting the amp. Then, pushed the rubber bushing
back into the hole. It wasn't a perfect fit, there was a slight
gap because of the red wire I installed. It also wasn't a
terrible fit - and then I put the headlight and headlight
retainer back into place. After continual testing at every stage,
and when I was sure all worked as it should, I used a dab of
black silicone caulk and filled in the gap between the rubber
bushing and the outside of the headlight assembly. This also
helped hold the red power wire in place and reduce any chance of
shorting against the headlight casing. I ran the ground wire
outside the headlight housing for a few inches to a windshield
mounting bolt and tightened it down. (I didn't want the ground
wire taking up space going through the headlight hole, so I split
the red power wire and the ground wire before the power wire
entered the headlight housing hole. You may find it works just
fine running both wires through, especially after using caulk to
close up the hole where the wires enter.) Finally, I used zip
ties to connect the volume button to the left side windshield
mount, very close to where my hand naturally fits onto the
handlebar grip. I believe you want the volume control where your
left hand can safely get to it without too much reaching. Final
result is my Boss audio system works only when the high beam is
on. And when the bike is turned off there is no chance of the amp
staying on and draining the battery. Also, my install required no
drilling, no running wires under gas tanks and seats, and no
toggle switch. I love having music now!!! Safe riding!
Review: Great wuality speaker - These speakers are perfect! I
bought them and installed them on my KLR. They were a little
difficult to install on the handle bars because of the thick
rubber strips to reduce size but once I got the nut started, I
was able to tighten them without issues and they are extremely
sturdy. The sound quality is amazing and I can hear my music
while cruising at 75. The Bluetooth connectivity is great! Cable
hookup is straightforward and didn’t have any issues with wiring.
