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.

### Bridging two12" subs and one 15" sub to my Rockford fosgate T 1500bd amp

assuming all 3 subs are 3-4 ohms, running all 3 in parallel (the 3 positive leads all attach to the amp positive terminal, and all 3 speaker negative leads connect to the amp negative terminal) will bring you at or above 1 ohm, which the amp is capable of handling. With 1500 watts, you will want to use 8 gague power leads for the amp, 12 gague speaker cables, and an inline 120 amp fuse between the amp and the battery, within 1 foot of the battery.

### Just bought a car with this stereo. Was working fine and then I accidentally was messing around trying to figure things out and put it in demo mode. Now it's stuck!! Can someone please help?!?!

With the stereo on, hold the large round button in to get to setting menu. When it gets to that, I believe clock adjust comes up first, just turn the knob to get to demo mode and then push the button in. Turn the knob to switch demo off and then push it again. That should do it.

### I have a Sony STR-KM7 AMP and the subwoofers have stopped working?

Sorry but it sounds like the subwoofer voice coil has shorted, you will need to replace the sub.

### So how do wire this set set up to a bridged amp any help would be appreciated

assuming that is a dvc dual 4 ohm speaker, and you have a 2 ohm bridged amp, you run a positive from each side of the speaker into the bridged positive of the power amp, and run a negative from each side of the speaker into the negative bridged terminal of the amp. if, indeed, you have 2 4 ohm voice coils, running them bridged in parallel wiring will bring the load to 2 ohms. if you have 4 voice coils, of 4 ohms apiece, you could run all 4 parallel into the amp, but that would bring the load down to 1 ohm, and you would have to make sure you8r amp can support 1 ohm operation.

### I have a boss 400w riot 2-4 channels,how do i connect the high level wires? Because stereo doesn't have rca's

to use the high level leads, you have to isolate the wires going to each speaker (if using 4 channel mode) or isolate the wires going just to the rear if you are using 2 channel mode. you have to strip a small piece of the insulation off each speaker wire, and run it into the amps high level input harness. if you dont have the high level input harness, you can get a 2 channel high level to rca adapter for around \$20. basically, you are tapping into the signal to the stock speakers to feed music to the amp. make sure you get all your positives and negatives correct. brighter wires are usually positive; however you may be faced with sa speaker which uses a grey wire, and another grey wire- the second with a black line. you will have to, again, turn to internet research to determine which is positive and negative, if the colors are not obvious.

### Lightning audio b150.2 as soon as +12 is hooked up blows 25 amp fuse and the c2 1000uf/35v capacitors blow???????

Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Double check all connections .A thumbs up would be greatly appreciated if this answer is helpful to you.

### RCA CABLES

RCA cables are the best way to get the audio from your head unit to the amp. If your head unit doesn't have RCA outputs, you might be able to use the speaker outputs of the head unit to connect to the "high power" or "high level" inputs of the amp, if the amp has such inputs (check your manual).
