Which Mazda 3 years can have subwoofer?
BK, built 2003–2009 (CD radio built into the dashboard, Bose on the Sport trim; no screen): Compact under-seat or boot subwoofer on a DSP amplifier fed from the CD radio built into the dashboard, tuned in the car; boot space stays usable. BL, built 2009–2013 (CD radio with a small display strip above the vents; TomTom navigation on some facelift cars; Bose on higher trims): Compact under-seat or boot subwoofer on a DSP amplifier fed from the CD radio, tuned in the car; boot space stays usable.

How long does subwoofer take on a Mazda 3?
About half a day on the Mazda 3 BK, BL, BM and BP. You can wait at the workshop or drop the car in the morning and collect it the same day.
What stays factory when you fit subwoofer on a Mazda 3?
On every 3 we work on — BK, BL, BM and BP — the factory head unit stays; the amplifier takes its signal from the car and under-seat woofers leave the boot free.
Do I need to book subwoofer for my Mazda 3, and is there a warranty?
Yes — send the reg or the year and generation (BK, BL, BM and BP) on WhatsApp or the form below, and we confirm the route, the price and the next free slot. The work carries a one-year warranty, and the workshop is in Rosemount Business Park, Dublin 11, Monday to Saturday.
