if everything was correctly installed then yes, but depending on what was used, the installer may have opted for a custom configuration. however, the fader and balance really should work.

The stock amp would be useless if you are going to uprate the rest of your system. Because you will play it louder. You could use it to drive the front door speakers, but I would remove it and fit an upgraded item that will actually improve your system.If you are going to install a new head unit then there is a very real chance that the amp in the new head unit will be better than the one installed by the manufacturer.

Sounds like one of your connections are bad. Go through them again and be sure everything is secure. Also, definately check the fader and balance settings, could just be that the fader is set to front and balance is set to left. Also, why did you punch the first one?

Hello.... I am sorry to hear you are having problems. The reason for this is that since you have a stock stereo, the shop (or person) whom installed the amp and subs used a line out converter. What this part does is allows the connection of RCA cables to the factory head unit. Almost all bass signals are always in stereo, so since you were only hooking an amplifier for just subs, you can actually just connect to just one of the rear speakers instead of connecting to the right and left. Just makes the install a little quicker. There is nothing wrong with this as I usually do the same thing in our shop. However, if you are going to be using the balance control, then you will need to go back to the shop and have them hook the converter up in stereo (to both rear speakers). Hope this helps!

Press the Rotary encoder (CDE-9845/CDE-9843
only) or press MODE (CDE-9841 only) repeatedly
to choose the desired mode.
Each press changes the modes as follows:
BASS → TREBLE → SUBWOOFER* → BALANCE → FADER
→ DEFEAT → VOLUME → BASS
BASS: -7 ~ +10
TREBLE: -7 ~ +7
Subwoofer : 0 ~ +15
Balance : L15 ~ R15
Fader : R15 ~ F15
Defeat : ON/OFF
Volume : 0 ~ 35

Check to see what type of stereo head unit is installed in the car first and foremost... next you're going to want to find out if the unit is powered and sending power to the speakers.

After you figure this out, you can then go about picking out a replacement set of speakers for your car. You also need to decide if you want to upgrade being that you'll be spending money on new speakers anyway. Audio is a very subjective matter so what sounds good to you might not sound good to the next person which is why I recommend you go to a stereo shop and listen to the speakers yourself with all the settings on the head unit its hooked up to flat (i.e. the EQ flat, the fader off, the balance set to the center, and soforth) as this will give you a better gauge of how the speaker sounds by itself without any help from the head unit.

Infinity is a decent brand and Im sure you'll be able to find replacements of the OEM speakers relatively easily if you want to go that route. You could remove the speaker, and probably check out Crutchfield which stocks most of the infinity line for your specific model of Infinity woofers.


Removal is a simple task of removing door panels if its in the doors, and removing some screws and undoing some wire connectors. All you'll need are some screwdrivers and possibly some pliers.

Schematics and specifications of your stereo system should be easy enough to find online by doing a search with google or bing.

hope that helps! =)

check you Fade and Balance,sometime the ground is used for two speakers sometimes a ground is used more then once will cause your problem ........Good luck......

thats not a good idea the much power taken from the radio will fry the radio a stock stereo usally has a 125 watt max so my suggestion is but a radio that can deal with the power

go to standby hold m-log button tell menu comes on display press up on volume control tell amplifier comes on display pess left on volume control tell display says amp on. the built in amp on the stereo turns of and on to provide better sound quality to the pre-amp out puts
