Some of what you say is true, but some is wrong. Sounds like you have a decent knowlege of this but a few misconceptions.
The alternator does not determain what your amplifier's wattage is, it only determains how much current the electrical system in your car will supply. Let's just assume that the wiring is proper and the connections are clean, so you will have minimum resistance from the alternator to the amp (less than .1 ohm). even with a little more resistance, it is still in series and will have very little effect on the amp unless the voltage at the amp drops below the turn on level of the amp. Most amplifiers require 12 volts. Most vehicles will supply 14.4 volts even with not so perfect connections at the battery or alternator. If the voltage at the amp is at or around 14 volts you are good to go.
If you have an amplifier that requires more current than your alternator can supply, you need an upgraded alternator. Your amplifiers ratings do not change. Of course you need to have correct wiring and good clean connections.
By bridging an amplifier, it does not take away from sound quality, don't know who ever told you that, unless you are refering to the fact that it is a mono signal. That is not degraded sound quality, just a mono signal. It does not change the s/n ratio or THD (Total Harmonic Distortion).

The real answer this person was looking for is simple.
The most power you will get from your amp will depend on the impeadance of your speakers, nothing to do with the remote. If your amp is rated at 2 ohms bridged, you can connect 2 subs that are 4 ohms each in parallel and then bridge them to the outputs. That is the most you can get and still stay within the ratings of the amp if it is rated at 2 ohms bridged. I do not know the ratings of your amp. Whatever the rating is in stereo, you can double that for bridged and be safe. Most subwoofers are 4 ohms single voice coil. some are dual voice coils and 4 ohms each voice coil, if you parallel those together it is now a 2 ohm load. It is very important to stay with in the ratings of your equipment, otherwise you can blow up your amp, short your speakers voice coils, ect.
It is important to have speakers that are rated (wattage) a little higher than your amplifiers output, that lowers the risk of blowing the speakers. If the speakers handle more than the amp outputs, they should never get blown. Sometime when you blow your speakers, it then causes the amp to get blown.
The wattage ratings of the speakers have no effect at all on the output of the amp. The ohm ratings of the speakers have everything to do with the output of the amp. The lower the impeadance (ohms) the more wattage output of the amp. This comes from the knowlege of something called "Ohm's Law" (P = E squared over R). Then you must make sure that you have the proper guage wiring for the speakers as well as for the power connections.. The only way to increase power in an amplifier is to lower the impeadance of the load (speakers). Just stay within the ratings of the equipment or you will be visiting somebody like me and paying me to fix your equipment.
And by the way, the magnet is not there to be used as a heat sink, it does not dissipate any heat, it is a magnet, it has an magnetic field, the voice coil is not sinked to the magnet. If it was, it could not move the cone in and out. The signal that goes into the voice coil creates a magnetic field in the voice coil which in turn works with or against the magnet, causing the cone to go in or out. The voice coil is connected to the cone, not the magnet. The actual sound is created from the cone moving in and out creating a change in air pressure which our ears hear as sound.
The super cap people use is for keeping the voltage level up. With a very current hungry system, the voltage from the alternator can sometimes be brought down by a big bass hit. The regulator in the alternator can not always maintain the proper voltage when the current exceeds it's limit. That causes the voltage to drop to adjust to the current draw (more Ohm's Law). The capacitor works kinda like a battery in this case, the capacitor stays charged up since it is on the main power line and when the amp draws heavy amounts of current it drains the capacitor first, before it drops the system voltage. Then the capacitor charges back up again rather quickly and waits until it is needed again.

SOURCE: how to mount amp

Turn your amp over and you'll see 4 holes one in each corner and you should gotten 4 v shapped pieces of metal with 2 holes each and 4 normally have to mount them on manually. I hope that helps.

If you unplugged the fuses, the amp won't come on at all. I'd say its a blown transistor, you can test this by opening up the amp and using a multimeter to check resistance on the transistors.

SOURCE: i have a volfenhag zx-8400 amp

The voltage prolly says like 100Mv-2v, it doesn't really matter, just know that that the lower you turn it the harder it bangs. The X-over depends on where your box is tuned, crank the knob down too about 40htz and you'll prolly be good, just don't turn it lower than your box's tuned frequency. And your rca's go to line input. And there shouldn't be a problem with mounting your amp vertically, you prolly just had a bad connection. Hope this helps if you have more questions please ask...

How can I change the battery of a remote control model # 99122?

I had the same problem and finally determined there is a small plastic tab on the underside of the cover opposite the screw. That tab is in the center edge of the cover. After removing the screw, hold the remote with the screw side up, then use your thumb to press down in the center of the cover on edge seam where the cover meets the remote body. While pressing down you will be able slide the cover off the end of the remote to expose the CR2032 disc battery. Replacing the cover by sliding it on is much easier than removing it. Hope this helps.

You have no vertical drive, only a small horizontal line across the screen. In older projection TVs this is usually caused by broken solder joints in the area of the vertical IC and possibly over the entire board.

Disconnect the power. Remove the back cover. Slide out the boards being careful not to break anything. Some wires may need to be taken out of holders.

Usually the board in question is on the right. It will be the one with the flyback on it. The flyback looks like a small cylinder with about 4 large wires coming off of it. They will be rubber and flexible. One each goes to each CRT.

You will need to remove the entire assembly to get to the underside of the boards to solder the unit. Sometimes removing the restraints will allow enough room to flip the board over and do the work.

Once the underside of the boards are exposed, solder all connections on the boards. Be careful not to bridge any connections.

Reassemble the unit and give it a test. If things went well the unit should work ok. If there are additional problems you might have to replace the vertical IC.

Thanks for using FixYa.

Yamaha mm8 keyboard lcd display only showing half screen

I know this is a lame fix....having similar issue with the mm6;

gently, turn the keyboard upside down, rest on a blanket or something--use your bed?

Leave it upside down for an hour or so, then turn it over and see if it works better. Worked for me.

Often freezes-solved by sliding phone up and down several times restarts itself 3 buttons on keypad no longer work

Hi,the problem you are experiencing is as a result of a faulty flex connector cable,it's bad hence it can send signals properly from the board to the screen which results to freezing of the phone.The solution is to replace the flex cable.
Here is a detailed solution to assist you in disassembling your phone and replacing the flex conn. cable;
1.Remove your back cover, battery, sim and memory card. Remove the four screws you see behind the phone.

2.Run your plastic tool e.g credit card,around the join of the battery compartment to release it.
3.You will see a connector ,it needs to be disconnected. Just flick the black latch up and pull the ribbon out.

4.Now remove the two screws on the upper edge of the phone. Both screws will be covered with red stickers.
5.Now move the slide down and remove the three screws you can see.
6.Lift the circuit board to the side slightly to reveal a ribbon attached to the underside. The connector attaches like a plug and socket. Just lever it away from the circuit board to unplug.

7.Pull the slider down to access four more screws. Remove these. Now run your fingernail or your plastic tool around the join of the front cover. This will release the clips which hold it in place. The cover will still be attached near the top of the phone so don't try and force it off .

8.The camera cover should now be loose. Remove the two screws you can see. You can now remove the front cover.
9.With the front cover removed ,the navigation pad and the part that holds this in place will come away with the cover
10.Pull the screen away from the rest of the phone. The c connectors needs to be released. For each, flick the black latch up where the ribbon enters and pull the ribbon out.
11. You now need to separate the LCD and touch screen. To do so you need to slide something flat and thin (the edge of a guitar plectrum would be best) between the LCD and touch screen. Try to follow the dotted line and try not to push your plastic tool too far under the touch screen or you'll get a sticky residue on the underside of it. Applying some heat with a hair dryer may help loosen the touch screen.

12.You should now have the LCD screen and touch screen separated. Reverse the whole procedure for reassembly.

Thanks and take care

Scanner failure error

Take the top off and clean the underside of glass as well as the mirrors on the scanner. Remove the bulbs. This is a light job but not for the mechanically impaired. If you have a 7110, take the ADF off by lifting 2 black inserts near the hinges. Remove 3 screws - 2 near ADF hinges and one on the right.
- Pop off the button cover.
- Remove button assy by sliding right, lift up and pull forward. Remove cable and 2 screws in view.
- Pop off the front plastic piece that the button assy. rested on.
- Remove 1 or 2 screws on the underside center of the top glass assy.
- Open printer exposing the print area and remove the front hinges on the bottom by moving the tabs on left and right side of both hinges.
- Remove a few screws holding the top cover in place.
Cleaning the mirrors.
- Remove the top plastic cover on scanning assy by inserting a small flat blade on the left and right (just behing the lights) and release tabs. Lift front upward till rear tabs are free.
- Remove the bulb toward the middle of the scanner assy. by unplugging, unsnake wire and lift up only that end enough to clearing so you can slide the other end out.
- Remove screw holding dont the clear plasic guide.
- Unplug the other light and unsnake wire. Lift that end up only until the clear plastic piece clears guides and then slide both plastic and light until the other end of the light is free.
Clean mirrors carefully and wipe bulbs carefully
Then Reassemble.

Sc-HT80 Problem

Hi one solution to your probelom is that the lazer is is a fix it 4 u. A major problem began 2 years ago Some New DVDs would not always play. Message on LED display says "NO PLAY". I discovered today that the problem lies with the laser being underpowered for some DVDs. On the web I found a fix. Warning! Always have someone competent with electricity to fix the SA-HT80 with the following instructions: 1. Remove all disks from player. 2. When door is open slide front door cover upwards to remove. 3. Leave door open. 4. Important UNPLUG FROM THE MAINS! 5. Remove the 3 screws from under the front panel then remove cover screws. 6. Disconnect player from the mains. Remove cover. 7. Once you have removed the cover you will see on left side is the drive parts. 8. Pull out the two flat cables which go to the Drive from the vertical circuit Board(Hold the cable with thumb and forefinger close to the connector and slide the flat cables out of their connector. 9. Remove the screws fixing the drive unit to the base of the cabinet. 10. Now remove drive unit. 11. Placing the drive upright on a flat surface proceed to remove the two screws holding the Plastic bridge that sits over the disk. 12. Also undo the screw on the small circuit board which holds the disk sensor switch onto the bridge and unclip that small board. Remove this plastic bridge over the drive. 13. On underside of drive remove the two small screws from the drive circuit board. You can now gently prize this board loose.(There is some resistance as a plastic clasp is holing onto the underside.) 14. Turn Drive back to upright position. 15. Remove the screws which hold the drive in(Screws go through rubber mounts to cushion the drive). 16. Once you have loosened the drive look at the underside and you will see one flat cable goes to the Laser. Where this cable meets the metal part you will see a tiny device connected on the outside edge of the flat cable. 17. Turn the POT 1/5 off a turn clockwise(looks like a small washer and be gentle with it) I used pointed nose pliers for this. 18. Now reassemble DVD player. 19. Ensure cover is in place and screwed down before connecting to a power supply. This is a guide which you will follow at your own risk. Happy fixing Gerald
