Since getting our new Abarth 500 in March the only issue we've found is the standard stereo. I've played with the settings a lot of just cannot get anything to sound half decent (radio, CD, USB, bluetooth).

So it looks like we should have paid a little bit more for the better stereo system. Too late now.

So what are my options? Upgrade the speakers? The headunit? I don't want to go OTT so the simplest option would be best.

If you are after a little more bass you could fit one if those under seat sub things?

I had an aftermarket amp and small sub in the boot and it's amazing. Have a look at the link below

Excellent, thank you.

Do you have any photos of the standard subwoofer?
