Re: i accidentall setup up my tv for ez scan now what??

When your in the EZSCAN mode and its scanning you can skip the scans that you want by pressing ENTER when it begins on the scans you dont want..It will tell you what is scan mode is DTV,CABLE,ANALOG TV .Press ENTER as soon as it scans the unwanted scan modes then let it scan on DTV ..

Which amplifier is best suitable for me to use?

This really depends on the setup you intend to create in your vehicle.

The Amplifer (amp) needs to be matched to the speakers you intend to run.

As a rule of thumb, the power of the amp shouldn't exceed the max. power of the speaker (this may damage your speaker). Instead, the amp's RMS output power should be at 75-100% of the speaker's RATED (RMS) input power. NOTE: this must NOT be confused with max power.

Ideally, you want to run each speaker with its own amp channel.

A subwoofer will usually require a hi-power single channel amp, or a 2 channel amp, bridged into 1 (to increase power output required for the sub).

Here are some examples in simpler terms:

1 channel (hi power) amp can run a subwoofer.
2 channel amp can run 2 speakers, or 1 sub (bridged).
4 channel amp can run 4 speakers, or a combination of 2 spkrs + 1 sub (bridged), or perhaps 2 subs (bridged).

Hope this makes sense.

I have a alpine type r 15 inch it has two hook ups i cant figure it out i have positive two pos and neg two neg and it keeps cuting out one bridge two amp plz help plz plz

Ok, for starters. Is your sub a dual 4 ohm sub? If so, great. Is your amp 2ohm stable? If so, then great. If you are running one sub, is your amp a monoblock (single channel) amp? Are you running a two channel amp Your subwoofer is a dual voice coil subwoofer. This means that you have to have power to both voicecoils or risk damaging the voice coils. Subs are designed with dual voice coils to give it more control over the cone movement. This results in better reproduction of sound. Anyway, back to wiring.

This is for a monoblock amp (you can also bridge a 2 channel amp) Go from the positive speaker out of your amp to the positive posts of both voice coils. Then go from the negative speaker out of the amp to both negative posts on the sub. And there you have it. It's called a parallel set up. Setting it up this way just dropped the ohms load for that sub to 2 ohms. Less resistance means more power to the sub. Hope this helps

Cannot figure out which buttons nvigate the menu. no cable hooked up to antennea and i cant figure out which uttons to us

Hello Pauline,

This appears to be a TV question (menu, cable, antenna) in which case I should be able to help you, but this is listed as a car audio question. Please can you let us know the brand and model number of the device you need assistance with.

If it is a TV, you should be able to navigate the menu with the UP / DOWN / LEFT / RIGHT arrows keys on the remote (if you have one). On some TVs - particularly older ones - or if you don't have a remote control the CHANNEL UP/DOWN and VOLUME +/- buttons on the remote or the front of the TV can be used to navigate the menus.

Please confirm the model number so I can give a specific answer for your TV - or whatever else it is. You can reply to me by clicking on "Add a Comment" below your question.

When i hook up my ipod to the kcu cable nothings happening and i cant even find an ipod source channel on the head unit itself

Is there an option for AUX or Auxilary input anywhere on the head? Try switching the input source through all possible settings while playing the ipod and ensuring the volume is on, to see if it plays.

I have a Phase Linear UV7i . everything turns, Except theres "NO SOUND" and the Screen Is " BLUE" and you cant see anything? Whats wrong with it? Is it bad and should i throw awat? HOW CAN I FIX IT? pLEASE...


Here is what you all need to do. In order to bypass the ebrake switches blue preventing screen you must take out the head unit and splice(tie in) the PINK park wire to the BLACK ground wire. Trust it works just fine after doing so, so you will not have to worry about the horrid blue screen no more. Or

) Insert the DVD and you'll get the blue screen.

(If you have more than one tv, the unit itself will have the blue screen but the additional tv's you have plugged in will NOT, they will show the dvd menu. Thus you will be able to see the hidden menu on the additional screens after inputting the code, but not on the main unit because of its blue screen.)

2) On the main remote, push stop twice and then 1, 2, 6, 4

3) Push the joystick on the unit SOUTH twice and then click it once.

4) Press system SETUP on the main remote twice to save your settings.

It may take a few tries but you'll get it. This method can be done if you don't want to bother temporarily activating the brake sequence, but if you only have the unit and no additional TV's, its #$%^&* damn hard because you can't see the settings your changing.

Thanks for contacting Fixya.

How can i bridge a mtx 9500 using a mono amp?

You cant bridge it to the MONO AMP . You can only bridge subs & speakers to 2 CH & 4 CH AMPS that are bridgeable. Because if it appears that there is 2 channels on a Mono amp its so its convenient for you to hook up 2 4ohm subs to it easily But both channels are actually connect internally together in parallel inside the amp unlike a 2 channel they are separate.

So just connect your mtx 9500 to a plus and a minus and doesnt matter which since all the + terminals of are connected together and - are connected together already.

Whats important is on the side of the sub/box it reads 2 ohms. The lower the ohms the more power the Mono amp will put out. Mono amps are designed to handle 2ohm loads.

If it reads 4ohms The MONO amp is the wrong amp to use cause the power will be weaker. So if you have a 1000 Watt Mono amp at 4ohms the sub will only get 500 WATTS Max while a 2 ohm will get the full 1000 Watts.

If it reads 4 ohms connect it to a 2CHANNEL AMP and BRIDGE IT (connect + of the sub to 1st channels positive of the amp then connect - of the sub to 2nd channels negative of the amp) . The power will be doubled when you bridge it on a 2 channel amp. NOW if it was a 2 ohm sub and you bridged it to the 2 channel amp it will fry the subs and ruin the amp. 2 CHANNELS CANT TAKE A 2OHM LOAD BRIDGED OK.

Hello george_nutti,

The model number you posted is for a center channel speaker which has no controls, and not knowing the exact model number it's difficult to be specific.

Some Kenwood KDC models allow you to select one of 3 "tuning modes", 1) AUTO1 - Automatic search for stations; 2) AUTO2 - Search Preset stations; 3) MANUAL - Normal manual tuning control. If your Kenwood is one of these models, you need to set the tuning mode to MANUAL. For Kenwood Excelon HD receivers, direct access tuning is done by using the included remote. 1) Press DIRECT button on the remote; 2) Press number buttons to enter desired channel number; 3) Press DIRECT button again to exit direct tuning.

Hope this helps.

JVC KD AVX1 car stereo will not tune in to any radio stations, just keeps searching for them, can hear de tuned stations badly. All connections are ok. Any suggestions? Thanks

standard problem would be antenna issue. Make positive that the connection in the rear of the unit has a connection. If it does, take it out, slip a single, small wire in the back of the smaller hole [typically 1 ft long]. Although this results in an impedance ,ismatch, it will allow you to see if the antenna is at fault. With the wire in the hole, scan through the channels. Fixed? Antenna issues. Not fixed? You have an electronic circuitry or setup problem. Try the 'local' and 'mono' switch with the real antenna still connected. Still no reception?

This becomes an electronic issue at this point which stems at the following concerns:
impedance circuitry [usually small, diode at output]
PLL IC faulty or no V

How can i get a 2ohm load outta 2 4ohm dvc subs can you show me how to wire the amp as well it says on the amp its 2ohm stable

A normal wiring setup to produce a 4-ohm load is what you usually see - each speaker is wired to one channel of the amp. This is series wiring. To get a 2-ohm load, you need to wire in parallel. Here's how:

Take sub A and wire the positive terminal to the positive terminal of channel 1 on the amp. Wire the negative terminal of sub A to the negative terminal of channel 2 on the amp. For sub B, it's the opposite - positive terminal of sub B to the positive terminal of channel 2, and the negative to the negative terminal of channel 1. That's parallel wiring, and will produce the 2-ohm loading (and subsequent increase in output) that you're seeking.
