I'm currently driving the two rear speakers with this unit, would it be possible to add the two front one too? Or would I be better off with a different model?

This is a 2 channel amp. Right and left. It is also only 4 ohm stable. As long as you do not have an ohm load lower then 4 ohms, you can run what you want on it.

However.... If you run 2 more speakers off of this for the front, they would all be on the same rear channel, meaning you will have no fade, and some songs that are designed to have parts of the song louder in the front then the back, will loose some sound.

If you want to run front and rear speakers on an amp in your vehicle, it is best to either have a 4 channel amp,or buy another 2 channel amp. This way you ohm loads will be correct, and your balance and fade will be as well.

Typical setup, 4 channel amp running the front and rear speakers, and a Class D mono block am driving a subwoofer(s) in the trunk area. In place of 1 4 channel amp, you can use two 2 channel amps.

yes, there is an amp turn-on wire from the head unit (black with a red stripe). You will need to add a power wire and fuse from the fuse box to run the amp. You can use the speaker outputs as inputs to the amp, depending on what you are trying to do. Please let me know if you need more help, and identify the amp model as well as the speakers you will connect.

Where do you hook up the external speakers?

Most common external speaker hook ups are RCA jack type or if it is an older unit it may have screw terminals. Most are clustered together and are marked clearly L or R channels and if it is a surround sound unit, it will have markings for front L, front right, rear L, rear R and center for 5.1; add two more channels for 7.1. These are located on the rear of the unit.
Hope this helps.

Subwoofer for alpine cde-9843

In short, no.

The CDE-9843 cannot drive a sub of the type you mention without an amp, but you can fit a sub with it's own built-in amp.

As standard, the head unit has a basic in-built amp supplying 4 x 16w RMS at 4ohms but there is the facility via the unit's own menu to turn off the in built amp and use the output sockets as a pre-amp feed, but in reality if you want to drive an amp you'd be better off to start with a more highly specified head unit to begin with, even the next model up, the CDE-9845 is better suited as there are pre-outs for front and rear speakers.

User instructions are available from here.

putting the extra speakers on wont solve the problem the unit has a max output it might give a better alround sound so it will be clearer a little but pushing to far on standard speakers wont help if you need better go for some active speakers there more exspensive but will give better definition and the volume limit might be higher.

Hey is ther any why i can run six Speakers off this head unit + an amp and sub system?

The head unit will drive four speakers, 2 front ,2 rear.
Best way to add two more speakers and a sub is to get a 4 channel amp. Hook it up to the RCA jacks from your head unit. Bridge two channels of the amp to drive your sub, and use the other two channels of the amp to drive the extra two speakers. Just make sure whatever amp you get it's bridgeable.

Battery powered Car Speakers

your problem would be in doing this ,is that the battery you want to use may not have enough amperage to drive the amps as they do draw a lot of current

Need to know

I would recommend running a four channel amplifier using component speakers up front and co-axial speakers in the rear. You can add more speakers up front, but it depends on what you're trying to accomplish in your car. Do you want it louder? Do you want it clearer? Any system will benefit from an amplifier. More power to your speakers will give you better sound because you'll have more accurate control over the speaker cone. This extra power will result in better clarity, not only at high volume, but low volume too.

Wiring new speakers

hello melgiblett, as adding additional speakers to you current factory speakers will cause and abundance of power drain, you head unit is only designed to handle 4 speakers.. the only option would be to either splice your front or rear speakers to the new 6x9's, however you will notice a significant drop in audio volume and quality as your head unit would not be powerful enough to run all 6. with the assistance of an amplifier, you may be able to acheive all 6 speakers
