Audi A3 8V with sound system - external amplifier upgrade

[oyvind_norway]

Hi, I tried to find at thread about this question:
I have original sound system with subwoofer in the back, but I want more punch to it and want to instal a external amplifier to get more power/punch/upgraded subwoofer. How do I fix this? Is there a plug and play harness on ebay I can buy with amplifier output or is this more complicated?

My car: 2014 Audi A3 8V with original upgrade sound system (not bang olufsen)

I'm not sure about an additional harness. If you got some cash change head unit android add extra amp to run alongside existing one. Then add a sub I have a 10 pioneer in boot 360watt amp bridged just for the sub. I need say no more regarding how it sounds

I want to use my original head unit, but I bet your solution sounds great

Think you need additional output to plug amp In to speakers are already wired. Not sure if you can alter sounds ie equaliser to get the best sound. Hardest part was running the live from battery. And remote I'm sure I posted pics

Check out my thread in the main A38v forum. Pictures in that need sorting, however. You can replace the standard subwoofer with an upgraded unit (and ideally an amplifier, too)
