MIRX450H

I just picked up a 2010 RX 450h, without the ML sound package.
Considering upgrading the speakers to come as close to the ML sound (or better) if possible.

Can anyone share what they have done to improve the quality of the sound in their 'non ML' RX?

ML is not that great either.
the ML in the RX 350 is not the same ML that you'll hear in an LS 460.
the culprit is the huge empty cargo area and a very weak subwoofer.

i added a powered shallow subwoofer and an amplifier.
that made a lot of difference.
