Don't hook door speakers to amp or they will blow. Plug the wires to amp input. 2 channels. Put one subwoofer one right channel, and the other on left channel. Do not use cross over. Use bass boost and put level at 3/4 max. Use the lowpass for subwoofers.
You would have to re-wire the door speakers and connect them to highpass if you want to use the amp on them. If you need to know your factory stereo wiring, you can find it at installer . com or the12volt . com

How do I program a Midland GXT760VP4


After installing and charging the battery pack (or installing alkaline batteries), turn on the radio by turning . Then press Menu once to set your Channel. Press Menu additional times to set other features. To set the channel to listen to Weather Radio, continue pressing Menu to the Weather Channel sub-menu (Channel 1 is 162.400 MHz). If you press and hold Menu for more than 5 seconds with the radio in GMRS mode, the radio will scan all 10 weather radio channels.

Midland has the manuals to many of their products here: http://www.midlandradio.com/Two-Way-Owner-Manual . The direct link to the manual is http://www.midlandradio.com/Resource_/OwnerManual/201/GXT760%20Owner%27s%20Manual%20.pdf .

Please let me know if there is a specific item you want to set up on the GXT760VP4.

How do get my magnum cb on 19


Its very easy on this radio because it has a built in frequency counter. I can't remember off the top of my head but its most likely band letter A, then turn the channel selector to 19. If you are on the CB channel 19, the frequency counter will read 27.1850.

If band A channel 19 is not 27.1850 then leave the channel selector on 19 and flip through the band letters until it reads 27.1850. once you have found it, that letter is the CB band. channels 1 - 40 of the cb band.

Power cord ?


What kind of radio is it? Looks like a Marine Band radio. Do you still have the owner's manual, as it will show the purpose for each wire. If you don't, write or email the manufacturer to get one. Most Amateur and Commercial gear simply has a red and black wire to get DC power to the radio. Sorry I couldn't answer your question better, but I've never come in contact with a four wire radio.

Purchased my son a second hand Mazda 626. Its fitted with a Philips Logic Control radio Philips No CW077A or Fujitsu Ten No CE-3434TY1. I obtained all the owners manuals with the vehicle but unfortunately...


Unless changed cby the owner it should be the last 4 digits of the VIN number which can be read from the label on the driver's door panel. If it has been changed, I'm afraid there is no way to retrieve it unless you can contact the previous owner.
