I have been struggling to hear my tunes on the highway on my 15 Special but I just couldn't get myself to plunk down large amounts of cash to listen to tunes on a premium bike that came from the factory with economy sound. Heck the Yugo's came out with better sound than the Road Glide does.
After some research and help from many of you (@wevesspot ) from THE BEST SITE ON THE INTERNET I finally have tunes I can enjoy even at 80+ MPH.
The parts list;
$160.00 Cerwin Vegas B54 1200 watt 4 channel watt amp-eBay.
$110.00 Infinity Kappa 62IX -eBay
$76.00 Biketronics BT355 Line Leveler (discount code)
$7.00 gold plated RCA male to male couplers - Amazon (I miss Radio Shack)
$16.00 10 feet each of red and black 10 gauge wire- auto parts store
$8.00 (approx.) five quick splice connectors, four butt connectors, two heavy duty ring terminal connectors, two 6" red and two 6" black 18 gauge wire, 18" red 18 gauge wire & some zip ties.-my garage
$4.00 40 amp inline fuse holder-my garage
$1.00 40 amp fuse-auto parts store
$10.00 liquid tape. auto parts store.
$391.00 total cost.
After replacing the stock speakers with the Kappa speakers I pulled the tank and seat so that I could run the 10 gauge wires back to the battery and hooked the black straight to the battery negative post and the 10 gauge red wire with inline 40 amp fuse holder to positive post. The ring terminal connectors were used to connect to the battery,, after all connections were made,, of course.
The amp comes with RCA wires with male connectors. So does the Biketroncs BT355 so I used the male to male couplers to connect the line leveler to the amp input wires. The stock HD radio output speaker wires plug directly into the line leveler.
The 6" short red and black wires were butt connected to the amp speaker output wires to give some length to the amps wires. I used four of the quick splice connectors to connect the amps speaker wires to the stock wires that run to the speakers.
The 18" of red 18 gauge wire was ran from the remote (REM) of the amp to the positive wire of the 12 volt plug in at the fairing (AKA cigar lighter). I used the fifth quick splice to connect to the plug in wire.
The REM acts as the switch to turn the amp on. It is connected to a switchable power source so that when it senses power coming on at the 12 volt source it starts to pull power from the battery. This is so you do not have to install secondary switch for the amp.
After all the connections were made I covered them all with two coatings of the liquid tape.
I then set the amp on top of the headlight and zip-tied it to the plastic brackets that the headlight wire connections were mounted to. Those connections got moved into a hole on the upper left side of the fairing.
The line leveler got taped to the top of the amp.
I turned the tunes on, adjusted the amp to what I thought was the sound I wanted, installed the fairing back on and the wife and I took a ride. I hit the highway, cranked it up to 80+ and didn't have to push the sound past 12 clicks. If I went past 14 clicks it hurt the hears.
There were some songs with more bass than others that caused some distortion so after we got back from the ride I pulled the fairing, checked to make sure the amp had stayed put, then adjusted the amp to take the distortion out.
When I first started looking to improve the sound on the bike I was thinking about adding speakers to the crash bars but with this set up it will not be necessary.
Yeah I could get louder with more speakers but I'm not looking to be a rolling boom box. I just wanted to hear Bob Seger as we are Rollin Away.
Here's a shot of the installed amp.
Thanks to all of the knowledgeable folks on these forums. You guys are very much appreciated.
