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.

Short circuit protection energizes. Check for any external short circuit with connecting sires to sub woofer. If it found OK, the sub-woofer output amplifier section circuit inside the set is fault. Short circuited component/s. Check and replace them. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.

I NEED TO KNOW HOW TO WIRE THREE 3012 THWELVES TO A 1800 WATT KENWOOD AMP


Its hard to tell what you can or cant do without knowing exactly which kenwood amp you are using. Generally speaking though most kenwood amps are stable only down to 2 ohms. you will be better off just using 2 of your 12s wired in parallel- that will give you a 2 ohm load. There is a way to use all 3 simply by wiring them in series, it will end up giving you a 12 ohm load on the amp though which will work fine but you wont ever achieve the full power that the amp can do.

My subwoofers will make no sound now


Go through the multiple menus of your head unit, and make sure the subwoofer setting is set to "yes".

Do you have the owner's manual for the unit? What make/model is the head unit?

I had my subs installed a month ago and a few days ago the subs are working,everythings connected but not working and my subs aren't blown out because i don't have my music that loud so whats the problem?


what model kenwood speakers do you have? what head unit do you have? do you know how they hooked up the rca cables to the back of the deck? if this deck has got 3 pre outs you may have lost the sub pre-out. are you amp lights coming on? if you are still having problems you can take a 9v drill battery or bigger and touch the wires from the speaker to the battery, make sure positive to positive and neg. to neg. the speakers should pop if they are ok, that should re-assure you on the speakers. let me know and ill help where i can. good luck

How to wire kenwood amp to kicker cvr 12"


How you wire it depends on how hard you want drive your amp. If your woofer runs 4ohm per coil I would wile it in series (amp +to sub +1 sub -1to sub +2 amp - to sub -2) then run it for a week and see if it has enough power. the lower your Impedance (the resistance load on the amp) the harder your amp works and more THD (noise) is produced. (Dclass amps aren't know for being clean to begin with) configured like this your amp will see 8ohms and sound the clean east. if this turns out to be not enough power wire it in parallel and double the output. wire amp + to sub +1 and +2 then amp - to sub -1 and -2.

A word to the wise... start with your volume very low and work up slowly most speakers will puk up the voice coil before the amp starts to get warmed up. you would hate to have to buy a new sub.

Have fun

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
