Need to install a cdplayer in 70 chevy truck?


Because of the year of the truck you will not have any wires pre-wired in the truck, go to a Radio Shack, car audio store or Best buy and buy yourself some speaker wire for vehicles, about 5 ft of 14 - 16 gauge yellow wire, 5 ft of 14 - 16 gauge red wire a couple of 10 amp fuses and 5ft of 4 gauge black wire.

You are going to run the Yellow, Red, Black wires together from the radio space where the radio sits in down to your steering column, the speaker wires will go to your speakers from the radio, a + and a - lead to your speakers and connect them as needed.

Now back under your dash you will connect the yellow wire from the radio to the 12 volt + wire under your steering columns 12 volt power wire with a fuse inline, if you hook up a test light to this wire it will light up the test light without the car switch being turned on, the red wire will hook up to your ignition switch wire and your balck wire to the vehicles ground chassis, basically ground that wire to a non painted surface of the vehicle. This radio needs to be hardwired like I explained.

Good luck and hope it helps.
Lex.

My subs/amp are not working


when you car is running, it charges the battery somewhat. So the voltage problem is not a problem. The red light means the amp is going into ''Protect Mode". This usually happens when something is wrong with the amp. Usually the amp is getting hot. Check all of you connectiong and check the final impedance of the subs. Make sure the amp can handle the impedance of the subs. If you need anymore help, message me.

Red light flashes on amp when you turn the ignition key.


It really sounds like a grounding problem. Recheck it make sure where it's attatched to the chassis is scraped to bare metal, an you used a clean, shiny bolt to attach it. Also us a voltmeter to check your power wire just to be sure it's not that, you should get 12-15 volts. Also just make sure none of your fuses are blown. And Use the voltmeter to check your REM wire, your should also be getting 12-15 volts there. If this doesn't fix your issue i'm at a loss to explain it..... Buy a new amp, and don't buy Boss, i've had lots, and lots of problems with them in the past.

Kenwood KAC-8401 light goes from blue to red when turned on


Either the amp is ad or the sub got shorted? You can check itby disconnecting the Sub and seeing if the amp comes on blue then. If yes, then the sub is shorted. If no, then the amp is shorted. Also chck the voltage AT THE AMP. Make sure that it is above 12 Volts.

Red protection light


If the amp is going into protect mode, it probably has shorted output transistors. To eliminate other possible problems, do the following.

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.

If the voltage remains near or above 12v, disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up, the wiring needs to be checked. If it still shuts down, the amp almost certainly has shorted output transistors and will need to be repaired.

My kenwood kac7201 amp wont turn on but it has power to it


Recheck the voltage precisely like this:

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.

Nothing from amp


The RCA "plugs" should be in an OUTPUT of the radio (sometimes they are INPUTS, like for an MP3 player..). Go to Sears or somewhere similar and buy an inexpensive Multimeter. Set it to DC volts and place the black lead on the GND termunal of the amp. With the red lead on the BAT terminal you should read roughly 12 volts always. With the car running and radio on, place the red on the REM terminal and again you should see 12 volts. If not it's the wiring. If the voltage is 12 on both then the amp is likely damaged.
