Help with installing my galaxy 98vhp in my kW t660

Unless you can figure a way to bypass the radios internal amp (which is probably more headache than what it's worth), you HAVE to run it to the battery. See how big those wires are? That radio I believe uses 8 gauge wire. Which means it draws some serious current. In other words if you tried hooking it to the truck's wiring, you'd cause a meltdown in a hurry. And you think your company would be pissed about hooking straight to the battery....

So if you can't hook to the trucks battery, then you essentially just have a pretty dash figurine. Might be time to take back tot he store or just sell/trade....I have a few radios here that DON'T require hooking straight to the battery to operate.....you in?

 

Yes, you will have to hook it directly to the battery. The beast has to eat. Don' t starve it. You can run into problems, if it doesn't have enough juice.
My advice is as follows. Try to find an opening into the cab. On my Mack, it's where all the wiring and plumbing for my iClimacab enters.
Next measure how much wire that you will need. Don't be surprised if you're talking 20 to 30 feet.
Next check the gauge of the wire, on your cb power cord. If it's a size 8 make your wire to your battery a size or two larger. Maybe an 6 or a 4.
Also you'll need a big enough fuse, mounted as close to your battery as possible.
Next solder it all together, and hook it up. Try to ground your radio to the truck chasis, close to the radio.
Also don't be surprised at the cost. It's gonna cost you a good chunk of jack. Just for the wire.

 

I spent about 100 bucks for the wire and big fuse at the battery......Really that is the only way that radio will work.
And I hope you are not planning on using the stock coax or antenna!

That radio MUST be installed the right way and good SWR or it will be a 500 dollar paper weight!

 

Yep. and some good thick wire that they use for stereo amplifiers will work. For best results make it twice the size of the radios wire. IOW, if it's 8 ga. wire on the radio, run 4 ga. off the batt to a distribution block inside the truck and hook the radio to the block.

$500 eh? Wow....I know where there's one f/s for $350. I don't need it though. But maybe I should go get it?

 

Just run the power direct to the radio....
I came out of the battery box and went along the frame rail to the fire wall.
Most trucks have extra rubber plugs on the fire wall around the steering.
Then i went from under the dash up behind the plastic window pillar and fished it through the overhead compartment.
It really was not as bad as i expected.

 

There probably isn't one. A distribution block is a device you buy at a car stereo shop for when you want to run say two amps in your car, it allows you to run one big fat wire off the batt to the block, then you can run 2 or more smaller wires off the block to the amp.

The only reason I said that is because, on some amps, it will tell you to run a bigger wire than what the amp has. You see the longer you go with a wire, the more resistance you encounter, therefore in some instances, you need a bigger than normal wire in to almost the device. A distribution block would allow you to do this. Or you could also just run a big 4 ga. wire in and then connect the 8 ga. to it but it's sort of a Jerry rigged way of doing it.

 

try and look in the fuse panel if not try and connect to the starter motor as it runs from the battery directly to the starter the only other way is to look at the battery compartment and see if there is a terminal for a jumper cable that is used ti jump start the truck some do have these fitted hope this helps
