Present for wife. Any ideas? I've got 24 hours to come up with something

Not this:




Mrs Moons wanted louder sounds in her car (Peugeot 206cc).

So I've got her new speakers for the front and back (to replace the original) and a pair of 12 inch subs with an amp and enclosure small enough to fit the boot when the roof is down - car already has new head unit.

By them big bass would have been my recommendation.
