audio

So I upgraded the head unit to a Pioneer MVH-X580DAB a few months back and now need to upgrade the OEM speakers. Head unit is 50w x 4 by my guess is that's peak power as opposed to sustained. What would be the easiest (no cutting) and relatively cheapest all speaker kit to get my music sounding...

Hi folks, Just wondering if anyone has stripped out or replaced the standard audio in their Z4? I'm wanting to upgrade / add to mine and was thinking if someone had removed their standard hi-fi or DSP install if they still has it. Mine only has the minimum setup Cheers Danny
