20 Most Recent Concept CC-452 Car Audio Amplifier Questions & Answers

How do you hook up Concept amp CC-452.

either will work fine, as long as it's a + from one channel and a - from the other.

check the fuses an make sure nothing is grounding off the amp which will make it go into protect mode

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.

Depending on which circuit the IRFP064N/mosfet was in then you either have a blown output section and you will need to look at the other mosfet's that work with the one you replaced or if it is in the power supply area then you will need to check the other mosfet's that work with it in the power supply. Of course you will have to test all the driving circuitry that is associated with either output or power supply, which ever is involved and be sure that the driving voltages are correct. Of course, in the power supply it would be a high frequency square wave of about 50% duty cycle. A schematic would probably be of great help. Good luck.

To the OP 'Anonymous'. There is no manual available. https://www.google.com/search?q=concept+cc-504+manual For Cricket Wireless.
