Question about Kenwood KAC-5203 Car Audio Amplifier

3 Answers

No sound I have a new Kenwood 12" subwoofer and an older model Kenwood amp...It was working a few days ago, but now I can't get any sound from the speaker. I checked the wires and I'm stuck. But the amp is working fine after I replaced the fuse it kept blowing. Can you help?

    The speaker is KFC-W1212DVC and the amp is KAC-X520. Just can't figure out why I have no sound. Thank you so much...

I made a check for your SUB on the kenwood site, but found no match.I suspect though, that the WOOFER is rated below 500w
while the amp is 1000w.
You may have overdriven the sub, burning it, and resulted in the fuses on the amp being blown.Hookup the amp to another speaker,
if it plays ok, your problem is the sub. Have the coil replaced.
kev tech.

Do not listen to his advise about replacing the fuse with a higher one. If it is the fuse on the amp that keeps blowing then do not replace it with a higher one. You will most likely fry components in the amp. Let me know what kenwood sub you have and what kenwood amp you have and i can tell you a proper way to wire them to ensure the fuse doesn't blow.

    Ok, if the amp that you listed is the correct model number then I don't know what that guy is talking about, The amp is only rated to 250 watts at 2 ohms. They should be almost a perfect match. The kenwood subs that I looked at where in the 300 watt and up range and judging by the model number you gave it is a dual voice coil so it is capable of 2 ohms. So do me a favor and check both voice coils with an ohm meter and if both of the coils read around 4 ohms. I should be a little lower than 4 but around 4. Then let me know what you find out. Good luck man.

Good day, check your spkr impedance, if 4oms use a posive spkr dividing network. if stills blows up replace a higher amperage of your fuse. ex.4A raise it up to 5A. the your amps consume higier current if more spkr wattage.

My subwoofers in my car are not working properly, I have a Kenwood Hu, 1000 watt 2 channel earthquake amplifier brand new, 2 Sony Xplod 10 inch subwoofers and a pioneer 12 inch subwoofer. the problem is...

I just got done with 10 others like this with the same problem, just look at some of my other solutions to see what you will be doing. Basically you need to upgrade your entire charging system to run these amps, You guys are not even considering the power draw that it takes to keep these things running at full power! You need to plan out your system way before you start to buy things to make sure that you will only have to install it once and do it correctly. It all starts with the power available from your alternator. You will have about 40 to 60 amps of left over current to use from a stock alt after it has to charge the battery and power the car while driving. That means you can have a head unit drawing 15 amps and a sub amp that will draw 35 to 40 amps before you will need to upgrade your entire charging system. Failure to do this will result in Batteries lasting 1 year a new alt every summer, your amps will burn up the insides a few times before you realize the importance of this all.

No sound

Sounds like the bumby road may have made ur output wires touch and short out some output transistors in ur amp. Or ur amp has bad solder connections. Either way have ur local repair technician have a look at it

Does an mp3 player put out enough power for input to KAC-624 amp?

Have you connected the rca plugs to the radio or amp directly? If you've connected it to the radio make sure that the input level controls are adjusted AND available on that model (it will say AUX, INPUT, SUBWOOFER, REAR, etc.) Connecting your mp3 player directly to the amp will not have enough juice to hear sound you need to connect it to the radio first.

I have an alpine head unit and a kenwood 1000 watt amp. I have two 12" subwoofers hooked up to the amp and thats it. I got my tweeters, and door speakers powered by my head unit. The bass was cutting in...

your amp may have burned out or try checking the fuse in the amp and the car also your channels may be burned or you may jus have water damage to the amp

The amp says it's 1 ohm stable, so assuming the DVCs are dual 4 ohm, you should be able to connect all "+"'s together and all "-"s together, like the picture below:

As for the amp shutting off for a few seconds, it sounds like it's either:
A) Not getting enough power at high volume.
B) Overheating.

The cap on the +12V to the amp should help, but putting a meter on the +12V might tell you whether it's dropping too low (<11V).

When you first turn the volume up, how long does it work fine before shutting off? Is it with the vehicle running or not?

Amp is on, Subwoofer works, but no sound.

here is a short test you can try, remove the rca audio cable from the amp & connect a diskman or toher audio o/p device that you can hook up with the same rca wires, turn on the amp & see if you have sound. you can also remove the speaker wires from the sub & using multi meter read the ohm's of the sub, most subs are 4 ohm. Hope this help locate your problem
