Question about 1994 Nissan Altima

Open Question

1994 Nissan Altima speaker 2-way?

I own a 1994 Nissan Altima and need to replace the rear speakers. I know that they are 6.5" in size but don't know if the original factory installs are 2-way, 3-way, or 4 way. One of the back speakers was blown so I was able to pull the plug from the speaker from access in the trunk, but don't know if I need to match the exact 2-4 way speaker in order to just plug it into the new speaker and have it work without messing with any of the wiring. I'm an amateur but pretty mechanically inclined and have instructions on how to do an install and some correct tools to do it. I just may not know the correct terminology. Thanks for any assist on this.

Try radio shack, or stereo sales/installation place for ready to go plug adapter. For a few bucks, it saves headaches, and butchering the wiring in case you want to re-install old one later when trading in or selling the car.

You can't use any of those - the large connector at the OEM speakers is because the rears are amplified. Your factory head unit puts out a line level signal to the rear speakers. There's an amplifier on the driver's side rear speaker (the box around the magnet that you can see from inside the trunk).

You need to either replace the head unit with an aftermarket one to drive your new speakers, or you need to tap into the amp connector and find the line level wires, break them out, put RCA plugs onto them, and plug them into an aftermarket amp, which you'd use to power your rear speakers. Doing it that way allows you to keep the factory head unit.

SOURCE: my front speakers and tweeters are blown

I work at a Chrysler Jeep dealer and sell parts, and I'm sorry to tell you but this is a little problem we have run into many times with these vehicles. The factory speakers are **** and of course we have no wiring diagrams showing how to install aftermarket speakers without replacing the head unit with an aftermarket one. I just had to do this with my Mitsubishi Galant when I bought some Focal component speakers for my doors. I went with the Alpine radio and it seems very nice and I think it will do great for your speakers also. Hope this helped.

How can i replace 1991 maxima radio system?

The original radio is a BOSE system and it has a buit in amp. So if you replaced the deck you need to replace the speakers all so. Don't cut the wires to hook-up the deck buy an addapter KIT. It's not just the stereo that runs though that harness the factory alarm does all so and that will cause you problems. Anyway back to the stereo you need to add an amplifier and problem sovled.

Hi my 2003 nissan altima radio not working no sound coming from speaker yet all light are on

Is it a standard version or Bose version? If it's a standard version then either the plug in the back came loose or the built in amp in the stereo is dying. if it's a Bose, then there should be a pre-amp some where under or behind the dash or possibly under or behind the rear seat/ trunk. In that scenario it's possible that the amp has gone bad. Another possibility regardless what version system is installed would be if a wire cracked and is showing somehow, grounding out causing the speakers to go out. Bad ground. maybe a loose plug behind the stereo. Also has the stereo every been replaced. Is it factory stereo and speakers.

LouNissan Altima My nissan run real rough and it acts like it is not getting gas and when it does start to run I smell raw gas what can be the problem

Check the fuel lines in the engine compartment - look for leaks - also check the fuel line from the fuel filter - most commonly located on the driver rear side, just behind tire. Also, consider replacing the fuel filter.

Have you removed the original connector from you original stereo? If you still have the original connector in place you can get a new connector from the Ford dealer that will plug into your existing wiring and into your new deck. Ford connections are unique to Ford and you need to adapt them for this application.

Take the car and deck to the dealer and tell them what you need. Everything just plugs in and your original amp and speakers in the car will work.

Having said that there was an adapter available at Wal Mart of all places that did work. You may want to check there.

If you have removed the original connector then you need a wiring diagram.

The amp is located under the rear passenger side window. You need to remove the plastic side wall to expose it if you need access there. You can trace the wiring if needed.

Under the front bottom edge of the rear seat are clips holding the seat in place. Open the clips and the seat lifts off. You can then get to the amp as needed.
