The mch is operating with ddr2 667 cl5 in single-channel mode

Read the manual!
The Bridge mode on stereo amplifiers is often misunderstood relating to actual operation and usage. In basic terms, when a 2-channel amplifier is operated in the Bridge mode, it is converted into a single-channel unit with a power rating equal to the sum of the power rating for each channel, at a load of twice that of the single- channel rating. For example, the CPX 1500 is rated at 750 watts RMS per channel into 2 ohms. The Bridge rating is 1500 watts RMS into 4 ohms (minimum load). Bridge mode operation is accomplished by placing the MODE switch in the BRIDGE position, using only the BRIDGE Speakon connector or the red binding posts for the output, and using the CHANNEL A input. All CHANNEL B input func-tions are defeated and serve no purpose now. Bridge mode operation can be used to drive sound distribution systems in very large public address applications. Another common use for the Bridge mode is in subwoofer applications where very high power levels are required to reproduce extremely low frequencies with ade- quate headroom. Such enclosures usually contain 2 or 4 loudspeakers to handle the power levels involved. For Bridge mode usage, the enclosure impedance must be 4 or 8 ohms. Never below 4 ohms.

The usb drive must have the boot file for the operating system there are videos on youtube shows you how to make a bootable operating system on usb

CPU-Z might mean that your computer is running in "Single" Channel. Running in dual channel mode is slightly faster. Maybe 5% or a little more. To run dual channel you need 2 sticks of identical DDR ram. Your PC might have 2 non-identical memory sticks that's why it runs in Single Channel.

its showing tha memory running in single channel that means u have one ram thats fine
if you want more install another one ram

Here you go....

most universal remotes will not operate menu fuctions or allow input selections. try using channel down buttton on tv . go all the way down to channel two then go down again to see if video1 or 2 comes up. if not access menu functions on front panel go to input select enter in manually mch

■The system will operate in single channel mode if the DIMM sockets are populated in one channel only.
■The system will operate in dual channel Asymmetric mode if the total memory capacity of the DIMMs in Channel A is not equal to the total memory capacity of the DIMMs in Channel B.
■The system will operate in a higher-performing dual channel Interleaved mode if the total memory capacity of the DIMMs in Channel A is equal to the total memory capacity of the DIMMs in Channel B. However, the technology and device width can vary between the channels, For example, if Channel A is populated with two 256 MB DIMMS and Channel B is populated with one 512 MB DIMM, the system will operate in Interleaved mode.

This will depend on the amplifiers capabilities.

I will give 2 different scenarios.

#1 Stereo configuration

If the amplifier supports an RMS power output close to the RMS input power of the subwoofers then run the amplifier in stereo mode. For example 150 watts RMS X 4 channels driven at 20-20khz. (If you can provide a model # for the subs and the amp your looking at I can help you further with this decision.

Wiring for this is easy and simply involves matching the connectors for 2 of the channels (Front or Rear) to each of the subwoofers.

#2 Mono Bridged mode.

If the amplifier is lower power but mono bridgable you can bridge two Pairs of channels and power each of the subwoofers this way.

Generally speaking a 2 channel bridgable amplifier will be able to at least combine the wattage of each channel into a single monural channel and in many cases its actually higher.

So you would bridge the front 2 channels into a single bridged mode for one subwoofer. and then you could bridge the read 2 channels into another bridged mono channel for your other sub woofer.

For example if you had bridgable amplifier thats 50 watts RMS X 4 you coudl very likely (Generalization based on quality of amplifier) send 150 watts RMS to each subwoofer.

Again I would need to know what amp you're refering to to provide specific wiring instructions. Many Bridging amplifiers either have a single switch that will send them to bridged mode or you would use the positive + terminal from one channel and the negative - terminal from the other channel or a combination of both.
