I bought the used active subwoofer for mazda 6 and would like to install on my cx-3.

There are 5 cables to be connected.
2 for power(Blue and Black): Is it connected to Battery directly or to original audio system?
How to connect the other 3 cables?
Could any one tell me?
Thanks.

On the CX-3 there is a Bose amp under the front seat that the speakers connect to.

If this really is an active subwoofer then it will have an amplifier built-in. You'll need to source the power for it and I'd run a new fused line to do this. Don't just tap into an existing power line. The correct way would be to use a spare position in the fuse box though simply running wires from the battery to the back of the car and adding a fuse to the + wire should be good enough.

As far as the signal goes, well, I can only guess since I don't speak the language in that last image. The fact that there are two "+" wires labeled slightly differently and one negative wire makes me think that you can tap into the existing +/- for the left or right speaker and the + for the other speaker.

This is purely speculation, though, so don't blame me if you fry your car's electronics.

There is a wiring diagram on page 8 here but its heavy going - you have been warned!

Wow! Can you imagine being a "mechanic" now-a-days!

The picture has the wire colors in Polish. Let me know if you need help with the translation.

I can. It is terrifying. If a part is not remove and replace most of the "mechanics" are lost. I definitely have a chip on my shoulder due to the extreme incompetence of Mazda dealers in my area, but I'm willing to wager other dealerships are no different.

Don't go there. I'm sure there must be a global Mazda master class in not phoning back.

I bought the same Bose spare tire subwoofer but the wirng is different. It only have 4 wire out from the harness.
1) thick Blue with red, connecting to 2 orange wire from the internal amp, believe is +12V
2) thick Black, connecting to 2 black wire from internal amp, pretty sure it is ground
3) Brown thin wire, connecting to yellow signal cable from internal amp
4) yellow thin wire, connecting to purple signal cable from internal amp

If any users have experienced on Bose sub please provide some info on it
a) the external brown and yellow signal cable, please advice weather it is high level input (speaker in) or line level input (RCA)
b) I believed it is mono connection for +/- signal cable, as there are some forums suggested that the it produced weired bass. need to swap the purple and yellow internally to get correct polarity in order to produce solid bass.
c) some internal amp came with blue remote wire but this internal amp has no REM wire. Is that possible to add the REM wire to the connector (same circuit board) ad install external relay?
d) the non-bose HU have no REM out. However, there is one Antenna amplifier power supply that trigger power antenna. Can this wire serves as REM cable and can remotely turn on subwoofer internal amp from all types of input (ie not dedicated for radio/tuner only)
