Adding custom Subwoofers

[GP740iM]

Adding (2) 12" JL subs or (3) 10" JL subs in a box with a JL amp rating 1000watts rms. Can this be done with the stick head unit and setup? Only want to add amp and subs.

Yemen. I got a JL W7 12" in my car. Sounds sweet. Perfect addition to the H/K system in the car. When done right, wont interfere with battery management system.

Is this what the need?

Yup. Amazing piece. It will also provide the remote output to turn on the amplifier. It auto senses audio signal then turns on amp. Also has built in X-Over to ensure smooth output. Accubass adds some Xtra bottom end. Make sure u get woofers that can handle the low frequencies if u use Accubass. JL subs love the bottom-end of Super Low frequencies and if adjusted right, its the perfect compliment to the already beautiful sound system supplied by BMW.

Forgot, also come with remote bass volume control knob but i did not use it. Found that factory EQ and bass/treble has enough adjustments to get sub system to blend perfect and when you want More/Less bottom end, just adjusting BASS level is enough.
