Question about Kenwood Car Audio & Video

I just tried to install a KAC-7204 amp and I hooked the power directly up to the battery and grounded the unit and the power light indicator doesn't come on and no power is coming from the actual amp. What am I doing wrong?

You need to connect the ACC cable from the head unit to the amp. It is normaly a blue cable, you may have to extend it depending where you have mounted the amp. The ACC cable 'tells' the amp to switch on when the head unit is powered up.

It could also be a blown fuse either on the amp itself or within the wiring for it. You should have used a power cable with a fuse block built into it, check them out.

When i hook my amp up it gives no power to sub and cuts off all audio, why


You mean it cuts off the audio to even your inline speakers? If so then u have a short and its putting your car stereo into protect. Recheck where u spliced into the speaker wire. If even 1 strand of wire is crossed it will cause a short

Power is hooked up. Ground is connected. Both subs are connected. The triangle light is red, and there is now sound. All wires are hooked correctly...


on most amp red isnt good that means it in protection mode try turning your setting on the amp down all the way and turn the volume down tell you can get sound out of them then turn up the volume to were you would to them most and set the to what sounds the best but make sure the light doesnt dim down when the base hits

I bought a kenwood kac 7204 amp yesterday and i hooked it up to one 12 and one 10 and it sounds good but it gets really hot and it even shuts off do you know what might be my problem??


What is the impedance you are driving. If the load is too low then it will cause the amp to go into thermal shutdown. Look up the recommended impedance for this amp.

Kenwood 7204 car amplifier flashes the blue light on top then blows the fuse''


Hello rogman9570,

I'd begin by checking all of the wiring. The most probable causes of this type of failure indication are:

• Speaker wire may be short-circuited.
• Speaker output contacts ground.
• Head unit (cassette receiver, CD receiver, etc.) or the amp ground fails.

If all of your wiring checks out OK, then the amp itself probably has an internal fault.

Hope this helps.

How to hook up kenwood kac-7204 1000watt amp


I found the manual & have pasted the url here for you. some things to keep in mind. according to the instruction manual this unit is rated @ 500W, not 1000W. Also to maximize the output you should use 2ohm speakers for stereo applications. Also make sure if you need to extend the power wire, use 10 gauge copper & make sure it's connected to the car battery thru a 60 amp fuse. Also make sure the ground is attached to a clean metal frame or body part by using a bolt & nut not merely a screw. Good luck. If you need additional assistance let me know.
