It depends on the generation. B7 (2004–2008): from €349; B8 (2008–2015): from €349; B9 (2015–2024): from €349. Fitting is done at our Dublin 11 workshop — send the reg and we confirm the exact price before you book.

Which Audi A4 years can have subwoofer?

B7, built 2004–2008 (Concert, Chorus or Symphony radio in a double-DIN slot, RNS-E navigation optional; Bose on some cars): Compact amplifier with an under-seat woofer, or a slim enclosure in the Avant boot. B8, built 2008–2015 (Concert or Symphony radio with a 6.5-inch screen, MMI 3G navigation optional, 3G+ from the 2012 facelift; Bang & Olufsen optional): DSP amplifier on the factory signal with a slim boot-floor enclosure on the saloon, or under the Avant floor.

How long does subwoofer take on a Audi A4?

About half a day on the Audi A4 B7, B8 and B9. 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 Audi A4?

On every A4 we work on — B7, B8 and B9 — 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 Audi A4, and is there a warranty?

Yes — send the reg or the year and generation (B7, B8 and B9) 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.
