Re: 4-8 Ohm Output Overpowered?
You weren't by chance connecting a powered subwoofer to the standard speaker channels? Most powered subs require a dedicated output from the amp, otherwise you would be amplifying the signal twice over!
a 6ya expert can help you resolve that issue over the phone in a minute or two.
best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

You can plug in higher ohm speakers , the higher the ohm the higher the resistance is, it is a danger when you plug lower ohm speakers into a higer ohm Amp , at a high volume that will cause them to blow , the center speaker would be fine to use a higer ohm speaker , your best choice is to buy a Active Subwoofer, which means the sub has it's own power supply , and u can blast the thing as much as u like , thn u can turn the bass down on all the other speaker's so u can play it louder , and have the sub turned up has high as u like , this is the best way to get great sound with high volume , buy a Active sub woofer , any active subwoofer is ok , a active sub woofer has its own volume and inputs on the speaker ,
First, I would purchase the amp based on the subwoofers alone. Allow unit power to run the 6x9's unless you are planning a intricate setup. Things to think about when buying your amplifier. Always get an amp that offers an RMS output of 25-30% greater than the combined RMS output of your subs. Also, the stability of the amp to handle ohms loads (1, 2, or 4 ohm stable). If you have two dual 4 ohm subs you can get a 2 channel 2 ohms stable amp, or a monoblock 1 ohm stable amp. This will get you the most power and sound for your buck. There are so many amplifiers out there at different price levels, it's really up to you. Hope this helps.
I'd need to know more about the amp, but don't forget, amps are rated as their max power... So lets take a 300W/channel stereo amp at 8 ohms. Ok, it's stereo, so there's 600W But the amp is capable of 4 ohm loads...well, now you can deliver 600W/channel, for a total of 1200W In this scenario, your amp is doing exactly what it was designed to do with those speakers. If you wanted to get the full 1200W out of the amp, you'd have to hook up 2 more speakers in parallel to the ones already there. This drops the impedance to 4 ohms per channel = 600W / channel. Yes, the power is split among the apeakers...300W per speaker into 4 speakers = 1200W so any way you look at it, there's your 1200W
1 OHM...ONE... sheesh now thats a low resistance for anything... If they are only 500 watts and they are in parallel, series well NO.. your amp puts out wayyyy too much for those speakers.. 1200w versus 500 watts by 2... srill NOT enough "Head room" for it to be safe... about half is all you could expect before Pop.. sound is heard.
Hi mate very nice amp you got there here is the specs for it
Model: MA Audio HK401SX
Hard Kore Series 1800 Watt 1 Channel High Performance Class
X Car Amplifier
1 x 1800W RMS @ 0.5 Ohm Mono
1 x 1200W RMS
@ 1 Ohm Mono
1 x 650W RMS @
2 Ohm Mono
1 x 500W RMS @
4 Ohm Mono Fully Unregulated MOSFET Power
Supply 2 Ohm Stable @ Mono 1 Ohm Stable @ Mono 0.5 Ohm Stable @ Mono
if you have 2 12s just bridge them and you will have 650wrms at 2ohm running to them or one sub at 4 ohm 500w rms ps they should pump iam running 2 12s with just 360rms at 2ohm and they do the job good luck
if you get the 4ohm you can wire it to run a 2ohm an the kenwood amp will push 900 watts at 2ohms.they say it can push up to 1800 watts,that would be at 1ohm.that kenwood runs 500 at 4ohms an 900 at 2ohm.if you need help wiring the sub or anything else let me know bertman285@hotmail,com
Max Power Output
4 Ohm [14.4V]
500W x 1 [20-200Hz, 0.5%THD]
2 Ohm [14.4V]
900W x 1 [100Hz, 1.1%THD]
The 2 ohm stable rating on the amp is PER channel meaning that you could effectively hook up a 2 ohm speaker or a 2 ohm load to each channel without the amp getting f"d up-butin bridged mode it will only be 4 ohm stable. to achieve a 4 ohm load with your sub the type x wire the coils in series that will get you at 4 ohms to run in bridged mono .But you will get the exact same amount of power if you wire each coil to one channel of the amp as bridged mono sees the sum of your 2 ohm channels combined-Hope that helps.
You are probably aware on how to use these output figures, but I'll write a quick explanation on the specifications for future readers anyways :)
The concpet CC-452 amplifier has the following power output specifications:
Calculated at 14.5 volts DC;
At 4 ohms per channel - 45 watts x 2 (RMS)
At 2 ohms per channel - 70 watts x 2 (RMS)
At 4 ohms bridged - 150 watts x 1 (RMS)
This means that your amplifier would provide 45 watts of power each for your front speakers, which are normally a 4 ohm load per side (45 watts for left, 45 watts for right), that's unless they are one of those exotic higher end brands (eg: Boston Z6s which are 3 ohms). Rarely, you will find speakers that are rated at 2 ohms per side, but in this instance the amplifier will provide 70 watts of power into each speaker. On your speaker specifications, you will find a value termed "nominal impedance" which will give you the ohm rating of the speakers being used..
On the other hand, if you "bridge" both channels into a single channel (using a diagram often marked on the speaker terminals of the amp), you could then provide 150 watts into a subwoofer (providing it was a 4 ohm woofer).
It's not recommended to use this amp bridged under 4 ohms..
Some subwoofers may be lower than 4 ohms, and you will not be able to use this amplifier for these types of speakers without risking amplifier failure. Also, some subwoofers may have 2 seperate voice coils, and you will have to use both channels of the amplifier seperately (not bridged) in order to correctly connect this type of speaker for use.
