I bought the antenna when they first released it. As far as the horns go, I split the source and sent 1 wire to each horn. I wired the grounds from each horn to the frame.
Most people just wire them in parallel, the wire for the horns supplies 12 volts anyways. My sickspeed horns are wired in parallel and I am very satisfied.
Ok so what type of relay would one use? I know a thing or two about electronics and there are many different types of relays out there.
Edit: and whats the real purpose of having the relay? I thought our fuse box had one already in it for the horn. At lest thats what I remember reading from the Hella vs sickspeed horn thread.
To make it simple:
A relay uses one voltage to control another voltage.
Relays stem from the basic desire to used a control circuit (low power) to control current and power flow of a higher power circuit (high compared to the control circuit). The are two basic types of relays electrical engineers use are, electromechanical relays and solid state relays. Relays can be used at relatively low power levels to high power levels. Electromechanical relays use a 'coil'(basically an electromagnet) which is energized to 'pull' in switch(can be a reed or a larger switch or contactor). Solid state relays use diodes and transistors which begin to conduct when the appropriate voltage/current is applied to the control input.
The source from the horn activates the relay, and then pulls current from the battery (using a fuse of course, as not to overpower the horns)
Spent 3 hours cleaning my wheels today *:icon_lol:
Inside barrels comparison (they came polished)
Outside all cleaned up and tire-shined
Threw 5mm spacers on in the rear - fitment is now perfect. Now I just need to push the rear links out 5mm to get rid of the spacers and get another alignment *:icon_lol:
