I’ve had the Z3 Subwoofer Stealth Box for about a half a year now, and honestly, I wish I had done it sooner.

It’s completely transformed the sound in these cars. Proper, clean bass without losing any space or messing with the car. Feels like it should have come like this from factory. Install was really straightforward. It just dropped in, plug and play, took me about 15 minutes. If you’re half decent with a spanner, you’ll be fine.

They’ve now got a UK package as well, just mention you found them through Zroadster and he’ll let you know.

I also managed to sort a little something for the Zroadster community. First 10 customers get a gift, which is $50 off add-ons. Worth jumping on if you’ve been thinking about it.

If this isn’t allowed, admin feel free to delete. Just wanted to share as it’s been a genuinely worthwhile upgrade.

Cheers.
