Basic 2 Channel ATV/UTV Stereo Wiring
|This howto will give you the basics of how to wire in and set up an amplifier on your atv or utv, for this we will be using an iPod/MP3 Player as our source unit, volume and song selection is controlled right from the iPod or other MP3 Player.|
Your 2 channel amp has 3 connections for power:|
* a +12 volt constant source.
* a ground.
* a remote turn on.
The +12 volt lead needs to go to your positive battery terminal
The ground lead needs to go to your negative battery terminal
The remote wire should be run to a toggle switch, illuminated if you wish, this toggle switch can be run right back to the battery so that you can turn on your stereo system at any time.
NOTE: Any time you connect a wire to your positive terminal on the battery it should have an inline fuse attached to it within 12 inches of the battery, this will prevent your ride from going up in smoke if the wire you run gets snagged or shorted to ground.
Next you'll need to wire up your speakers, one wire to each terminal, You should group like speakers on the same set of outputs, ie channel 1 & 2 could be a pair of 6 1/2" speakers, or a pair of 5 1/4" etc. They should be a matched pair of the same wattage.
I'll cover hooking multiple sets of speakers up to a single channel in another section so if you start putting 4 4 ohm's on a single channel you'll likely overheat the amp and run into problems keeping it cool. (*Clever wiring of your speakers can easily fix ohm load issues.. if you plan on running 4, 6 or 8 speakers off a single 2 or 4 channel amp email me for help!)
Finally you'll need to connect your signal wires. You'll need a Headphone to RCA Adapter such as this one:
Make sure you get one long enough to reach from your amp to your ipod.
They're easy to come by, you can find them at radio shack, wal-mart, k-mart maybe an auto parts store, or your local car stereo shop.
Once you have them, connect the RCA ends of the 3.5mm to RCA adapter to the RCA inputs on your amplifier then plug the other end into your iPod / MP3 Player.
Volume is controlled completely from your ipod, plug it in, press play, turn on the power switch to the amp, then adjust the volume on your iPod.
Your amplifier will have a couple dials on it to set the frequency and gain control, start by setting the gain on the amplifier to no more than 75%.. Running the gain wide open will likely just give you distortion at higher volumes, Set the frequency controls on the amplifier to cut out heavy bass on smaller speakers or if it has a crossover set them to HIGH PASS, Larger speakers or speakers that are in some sort of enclosure can usually handle running FULL RANGE, not LOW RANGE (this setting is for subwoofers). use the crossover dial's to fine tune the sound so you have lots of volume and no distortion. If the sound is muddy at high volumes you need to adjust the amplifier until all the speakers are crisp and clear without distortion.
