Agreed Hurdy,
But as an in-between, the OEM speakers aren't BAD.
They'll never stand up to some Hertz or other good aftermarket, but as a stop-gap after changing the H/unit, they're not a bad compromise.
What helped mine (which in all fairness would make the difference) is the fact that I've got a 12" sub bolted onto the system - the OEM speakers have been filtered to take this into account.
I've got some components ready to fit, but haven't got around to it yet - as the OEM ones don't offend me so much. I had anticipated changing everything, but haven't felt the need yet.
