Question about Kenwood Kac-m846 4/3/2 Channel Amplifier Car Audio Amp

1 Answer

Which speakers (Front/Rear) to buy that match Kenwood KAC-M846 4/3/2 Channel Amplifier.

I do not know what speakers (Fronts/Rears) to buy as the most rear 6x9 speakers have power rating of 110 watts@ 4ohms each but amp is only 50 Watts/channel @ 4 ohms. Does that mean that the amp is highly underpowered and not suitable? Most articles say that amp power should be more than the speakers nominal input power.

    Note: Speaker input power is nominal not max power. Please bear that in mind when answering the Question

I don,t no where you are reading thease articles from,I installed car audio equipment for over 40 years, Untill i retired a couple of months ago, Who ever is writeing those sort of articles does not have the slightest clue what they are talking about, It is the opposite way around, It is allway better for yor (Speakers) To handle more power then what your amp puts out, Then you will not blow the spaekers, It is best to get speakers at least 20 watts more then what your amps maximuin (RMS) Watts are, Hope this helps you out, (PS) 50 watts (RMS) Is what most people go for, It is in no means (Under) Powered.

    "Driving a high power capacity speaker with a very low powered amp is more dangarous than a high power amp driving slightly less power capacity speaker. It is the low power amp when maxed out , clips and causes maximum damage to speakers." This is the bottom line message in most video reviews and articles. for examplehttp://www.crutchfield.com/S-z38o4EjeILG...

SOURCE: KAC-9104D output terminals

ok i have the same amp and 1 2ohm dvc sub and was woundering the same thing but from futher research and askin sum xsperts. What i found out is that it is only one channel and even tho there are 2 (+) and 2(-) they actually connect inside the amp makein it one . so if u wanted to wire sumthing parralel u wouldnt have to hook wires from one coil to the other on the speaker , u can just hook it up to the amp. so basically both +'s and negatives on the amp are actually one within it so all the power if you only use one set of them and if u wanna add more subs its just easier to add to the amp by using the xtras .

Ihave a keenwood kac 7252 amp that is running two mtx thunder 4500 12`s but amp fuse keeps blowing at higher volume why?


1.-check proper heat sink, or dissipation.
2.- check speaker impedance. Must match between amp and speakers.
3.-low power line on the house may cause low efficience work on the amp, overheat, and finally fuse protection.
4.- finally, check speaker wires. Thin cable overheat amp too.

I would recommend running a four channel amplifier using component speakers up front and co-axial speakers in the rear. You can add more speakers up front, but it depends on what you're trying to accomplish in your car. Do you want it louder? Do you want it clearer? Any system will benefit from an amplifier. More power to your speakers will give you better sound because you'll have more accurate control over the speaker cone. This extra power will result in better clarity, not only at high volume, but low volume too.

Yes you can use the speaker output in conjuction with the rca pre-outs...but depending on the wattage of the amp, there may be a big difference between the loudness of the front speakers over the rear speakers. If you have a 4 channel amp you can put the rear speakers on the amp also and lower the input gain for the rear speaker. Or if you have a 2 channel amp, you could use a passive crossover to filter out some of the bass to the rear speakers since they are smaller, this would help prevent over-driving them...as it is normally too much bass that distorts and blows a speaker. I'm not sure what you are asking about the hi-rear preouts vs the mid front pre-outs. If you decide to use the amp for the fronts you should be able to connect the amp from the front preouts of the deck. Hope this helps.

If your amplifier has what they call High level inputs (basically inputs on the amp that you run the speaker wires from your radio into), you can splice wires from where the connectors are on your rear speaker(s), still leaving the speaker hooked up, and use those as an input into the amp. If your amplifier does not have high level inputs, a convertor is available to turn an audio signal from your radio output speaker wires ( spliced in just as above, leaving the speaker hooked up), into an rca output jack. Or the best thing to do would be to buy another say 2-4 channel amp w/high level inputs and rca inputs and outputs, and run your rear speaker wires into the amp. Then you'll be able to run the rca cables out of that amp and into the sub amp, and you'll have the new amp to power your rear speakers or rears and fronts. That would be ideal. But, A convertor is your best bet. Got em at best buy, circuit city, etc. Hope this was helpful.

My back speakers wont produce any sound


OK I believe there is a small indented "Reset Button" around somewhere on the back of the unit, With the unit powered ON, & using a small diameter implement, straightened paper clip etc, press IN the button and this should "Reset" ya unit. This may indeed fix all your problems as the Unit "Reads" the speakers at turn on.
