Finally got round to finishing up stage 1 of the audio upgrade. No subwoofer yet, but running new amps, speakers and headunit. Setup is: - Pioneer MVH-8250BT (http://www.pioneer.com.au/Products/Car%20Entertainment/Media%20Centre%20Receivers/MVH-8250BT.aspx) - 2xResponse 2-channel 150w RMS (bridgeable to 500w) - Polk Audio MM6501 6.5" Splits - Polk Audio MM691 6x9" coaxial Sound is excellent, just going easyish on the drivers to bed them in before I give them a good run but the sound quality is much better.
