Where is the wiring harness for the tundra, is behind the headunit in the dash or elsewhere? i want to hook an after market amp to my new tundra but would hate to remove the headunit to do so. please help
I'm afraid you must go to the back of the headunit... your only other option would be to catch the wires in the door sill going towards the back, or catch them in the kick panels going towards the front doors. This will prove to be much much harder than just removing the headunit.

You need to connect the Power wire (Most likely red wire with fuse) to the battery and run it to where you put the amp. You need to also drill a whole in the car and make sure it is grinded up and bare metal is shown. Screw the ground wire there with a bolt and nut. You will then need to run the rca cables from the amp location to either the back of the headunit if it has RCA outputs, or use a Line out converter, you can get them at best buy. Then you need to find your cars wiring harness code and figure out which is the remote ignition turn on and tap into that and feed that wire back to the amp to turn it on. Hook all wires up and make sure power and ground DO NOT TOUCH.
how is the signal going from headunit to the power pack? Should have a harness from the power pack to the deck (h/u). then out to the factory harness in the jeep. remember there is an amp under rear seat so you need to bypass that to make everything work. yes the blue/white wire from deck to blue/white wire ath the power pack (amp) should be connected in order for the power pack to turn on.
All amps are basicly the same. It should be plain as day where the speakers connect to. The 12V screw connects to the main power from battery, be sure to fuse that wire and use a proper size wire, thicker is better,I suggest at least 8gauge with 40amp fuse. The GND is ground and should connect to car metal, file paint for soild connection. The REM is remote and connects to the remote of headunit or if you have a stock deck to the acc of car found in wire harness of headunit. Plug in the RCA's to head unit, or get a converter to plug into speaker wires from car if you have a stock headunit.
The inline fuse goes on the power wire (as close to battery as possible), and is there for a sfety feature to keep from sending to much power to the amp. All it does, is simply blow if the power gets over the specified amperage. For your amp, I would use a 40-60 amp fuse.
The remote power line, is simply an 18 gauge wire, running from the headunit to the amp. All it does is tell the amp when to power up. Since the amp is straight to the battery, it is possible to be on at all times, so you run it to the amp so it knows when to be on. If your headunit doesnt have a remote turn on wire, then tou need to run it from the ingnition to the amp.
For a signal cable, I recommend getting an rca cable to run to the amp from the headunit. Make sure when you run it that you run it away from the power wire to prevent from having engine noise.
You also need a ground wire, wich should be to a stud on the frame of your car, as close to the amp as possible.
When hooking up your amp to the sub, you need to run the negative to the negative (black to black) and the positive to the positive (red to red).
Yes!!!!!!!!!! Your remote wire is what tells your amplifier to turn on and off it won't work without it. Assuming your stereo headunit is an after market unit it has the correct wire for this. what you have to do is pull out you headunit, and in the back of the headunit where all the wires plug into your unit there is blue wire with a white stripe. this is the remote turn on wire. connect a wire to that blue n white wire and run it back to your amp, insert it into to the spot marked remote. turn your head unit on and your amp will power up... if you have all the rca cables hooked up your amp should be ready to go.... btw good choice on the amp, kenwood is the way to go!
Since you did not specify the make and model of your aftermarket radio, I cannot pinpoint specific connection problems. Most aftermarket receivers have a "remote turn-on" lead, probably blue, but sometimes blue/white, usually terminated with a spade lug. In addition to power and ground, the amp requires this lead to be connected in order to properly operate.
Start by checking the wiring from the old receiver wiring harness and see which wires and what colors went to the stock amp. Then connect the corresponding wires from your new receiver to the amp. Some OEM receiver/amp systems had power and ground taken from the same harness, so you may need to run those separately.
check the ground conection and the remote conection if this one is conected to the headunit be sure to have it. if you are using a pre-amp equalizer check the remote conection on it too!!! it maybe the remote from the headunit to the amp or try to conect the remote cable from the amp to the antena remote cable on your headunit.
