Sony CDX-M630 Car Radio Product Description:

Sony's Xplod CDX-M630 emulates the quality of a home stereo in the car. This receiver is packed with all the power that you've come to expect. The CDX-M630 features ABC tuner, RM-X4S option, CD text, CD-MD control and custom file control. It plays CD-Rs and CD-RWs as well as CDs, and has Sony's EQ7 to fine-tune the sound contour. Seven preset curves plus a 7-band equalizer help you get it just right.

The Sony CDX-M630 is a very simple design. Its look and size does tend to belay its ability though. The small control panel (Which flips down) is surprisingly easy to use and doesn’t hinder the operations. Sound quality is decent with CD-R / CD-RW support. The system comes with a remote, but it seems bulky in comparison to the rest of the unit. The faceplate also isn’t detachable, so you cant take it with you when you have to leave your vehicle.

Panasonic DMP-B15 Portable Blu-ray Player - Non-stop Entertainment

Panasonic DMP-B15 Portable Blu-ray Player - Non-stop Entertainment

Panasonic is well-known for its quality, value and innovation. They distribute high quality electronic products all around the world.

Recently, Panasonic has released a Blu-ray player -- DMP-B15, a portable 8-inch DVD player having features like a 16:9 wide LCD screen offering a unique style of watching.

Its free style watching ensures the screen to be swapped to a broader array of positions for watching. This DVD player has a large viewing area to enjoy DVDs more comfortably.

Audio Video Cables Installation

Audio Video Cables Installation

Cables and cords are essential to operating your favorite device. Component video separates the video signal into individual streams and these video streams are carried via three cables, colored red, and green and blue that normally comes bundled with RCA type jack connectors. Component video signals will provide better color resolution, purity and fidelity than S-Video and composite video signals.

For electronics like televisions, digital cameras and camcorders there are DVI cables, HDMI cables and S-video cables. Also, HDMI cables are used for content management. For example, a manufacturer would use it to enable service providers to control access to specific content.

DVI stands for Digital Video Interface, while HDMI stands for High-Definition Multimedia Interface.

The biggest difference between DVI and HDMI is that DVI is used solely for video and HDMI cables carry both the video and audio signals through one signal. There are RCA cables, which are also known as composite cables, which include one connection for video which is usually yellow and it includes parts for left and right audio channels, which are usually white and red respectively.

Audio video Cablesare higher quality analog video cables which are generally used in hooking up your television, VCR, DVD player, or similar to another video source, such as a computer. There are also component cables which are essentially providers of higher quality and better signal throughput.

The principle idea behind HDMI is the use of a single interconnects instead of several cables when connecting an audio video source, such as a set top box or DVD player and an audio and or video monitor, such as a plasma TV, over a single HDMI cable.

The use of a single HDMI cable that replaces the maze of cabling behind home entertainment centers is the primary advantage brought about by this new standard. This is not the case with DVI supports digital video only hence, a separate audio cable is needed to transport digital audio when a DVI cable is used.

Audio Video cables are used to hook up receivers, tuners, radios, stereos, micro shelf systems and speakers. Other cables that are also used in audio video equipment are optical cables which are used to transmit light as the signal and coaxial cables. For cords, some of most popular are actually wire harnesses which are used in cars to power a car stereo.

Amplifier Troubleshooting

Please try these things before sending in your amplifier. By the numbers, 40% of all amps returned to us work just fine and there is a problem in the wiring or install.
You must have a DMM (Digital Muti Meter) and know how to use it.
If no: take it to someone who does.
If yes: thumb through the following scenarios

Amp will not come on (no lights):

Set DMM to DC voltage and check at the amp. You need to test with both (+ & -) leads on the amplifier Power terminals.

If over 12 volts: check both sides of the fuses in the amp.
If no or low voltage: ground the DMM (-) test lead to a good, clean, metal chassis ground in the vehicle and retest.

If over 12 volts now: problem is in the ground wire or connection (between the amplifier and its chassis ground).

If still no voltage: check both sides of the fuse by the battery.

NOTE: You cannot check a fuse by just looking. Fuses can be “bad” and not blown; especially the larger, cheap-ass, glass ones.

If blown or bad: replace and start beatin’ again!

If all is good with battery voltage, it is now time to check the remote (or turn on) wire. Check voltage at terminal of amp.

If no voltage: check voltage at head unit. You can also make a jumper from the main 12V+ connection to the remote terminal to see if the amp comes on. If it does, the problem is in the head unit remote output or remote wire between the head unit and the amplifier.

If all power wiring tests good, remove the amp from the vehicle and test with short jumper wires directly at the battery, using a jumper wire from amp 12V+ to the remote terminal, just as a “I need to make sure” final test. If it still doesn’t come on, it needs to be sent in.

Amp turns on but goes into protect:

Disconnect RCAs and speakers and try turning the amp on again.

If it still goes into protect with just power, ground and remote; the amp is bad.

If it is now on and not in protect: connect the RCA’s first.
If it goes into protect: the problem is in the cables or headunit. Change and retest.

If still not in protect: reconnect speakers
If it goes into protect: problem is in the speakers or wiring (most likely shorted [or grounded] wiring or burnt coils). Set DMM to 'ohms' and first test by shorting leads together. This number (usually in the .4 range) will be subtracted from any reading you get. Connect DMM leads to each speaker wire pair. If you have a short, reading same as touching the leads together, trace the wiring to find short.

If no short in wiring: test the speakers individually and eliminate problem.

If amp comes on (and not in protect) and has no output:

Check all settings. Turn deck on at low volume.
       Master/Slave switch in master position.
       Gain all the way up.
       Subsonic filter all the way down.
       Boost all the way down.
       X-over all the way up.

If still no sound: you will need to try an alternate input. The best is a signal generator right to the input of the amp. Alternately, you could use another radio wired in with temporary wiring right at the amp with a very short, known-working RCA cord.

If still no sound: try a known-working test speaker with very short wiring right to the amp terminals. If still no sound: amp is bad. This is a very rare failure but it can happen.

Amp has distorted output:

Same test as above. You need to eliminate all the variables.

If you are testing a stereo amp and you have the problem on one channel:

Swap RCA’s: if it changes sides, the problem is in the deck or RCA cables.

If same side: swap speaker outputs at the amp. If it changes sides, the problem is in the amp. If it stays on the same side, the problem is in the wiring or speaker.

Amp plays but has low output:

Check all settings. Turn deck on at low volume.
       Master/Slave switch in master position.
       Gain all the way up.
       Subsonic filter all the way down.
       Boost all the way down.
       X-over all the way up.

Turn up the radio. If problem remains:

Check voltage drop at amp power input terminals. Set your meter to DC voltage with the hold feature activated. If your meter does not have that feature you will need to watch it to see how low the voltage drops when it is trying to play loud. If voltage drops below 11 volts at any time, you need more battery/alternator power and or better wiring.

If voltage remains above 12 the entire time, you need to check the speakers.

Set meter to ohms and check the DC resistance of the speaker load. If it falls within the proper load for the amp, check the amp, hooked to known-working speakers. If new speakers work, the problem is in the speaker system. If it still has low output, you need to check the inputs as described above with a known-working deck and RCAs.

Amp plays but cuts off and on:

Attach volt meter to power and ground terminals at the amplifier.

Set the meter to peak hold (max/min) and display "minimum DC voltage".

Run the system until the amp shuts off and check the voltage. If voltage has dropped below 10 volts at any time, check all wiring.

Leave the meter positive on the battery wire and use a good, clean ground point on the vehicle and test again. If voltage has a higher reading than before, the problem is in the ground connection.

If it has the same voltage, work your way back to the battery; testing at any and all connection points. I.e. distribution blocks, capacitor, fuses, etc.

If at any point voltage goes up, you have found the voltage drop point.

Single vs. Multiple Drivers

There are advantages and disadvantages to either approach. For this, let's consider a scenario where the cone area of a single driver is equal to the cumulative cone area of multiple drivers: An example of this would be a single 10" woofer with an Sd of 50in^2 versus a pair of 8" woofers with an Sd of 25in^2 each.

The single driver advantage: Linearity. A single driver system isn't subject to the acoustic or electrical forces countering in phase--even if by a fraction of a degree--which typically occurs when multiple pistons share a common space or when multiple inductors share a common circuit.

The single driver disadvantage: It has been my observation that a single larger driver will typically exhibit higher equivalent air compliance (Vas) than the combined compliance of two smaller drivers. This can translate into higher Vb requirements.

The multiple driver advantage: Assuming that the motor structure is the same on both the 8" and the 10" model, the immediate advantage is twice the motor for every square inch of cone area, twice the power handling, and more end-impedance versatility.

The multiple driver disadvantage: As stated above, using multiple independently actuated pistons increases the risk of the electro-mechanical forces countering one another. This is particularly evident with high Qts drivers.
