Hey. I upgraged the stock speakers for Alpine's SPS 410 as soon as I got the bike delivered last winter.
Sound was better but I was missing some volume when I got strong lateral winds or at higher speeds. I can use the NAV VI to stream BT in my helmet but I prefer the fairing speakers, less fatigue on long rides than in the helmet... so no need to rant about the noise... my music does not bother anyone on the highways and I turn the volume down in residential areas.
So I got a good price on a used Rockford Fosgate 2 channels (thanks Soundman05
) to boost it up a bit.
Panier removal is easy once you know there is a plastic tab to push from the top after you removed the 2 screws inside the panier.
I used 18GA for speakers and 10GA for power, with an inline 30A fuse.
Amplifier is turn ON/OFF by the signal detection from the stock radio, thus I did not install the remote wire.
Amp is secured with 4 x ĺ" long x 10 stainless steel bolts with SS nuts with nylon locks.
I installed a 11/16" rubber grommet so I can pass the connectors through it if I have to remove the panier. I'll probably wedge a piece of neoprene to "seal" it since there is a little bit of space between the wires.
Solder every wires to make it look as clean as possible.
Now the real question... what's the easiest way to remove all the dirt under the seat
... I want to try a paint brush with compressed air
