This may be over the top upgrade, but worth it for the quality. I love music, so it MUST be clear at all volumes. I love to hear every instrument and sound in the recording. That being said, the OEM system wasn't too bad. Decent highs, so so mids, and average factory for lows (bass). But I wanted more volume, clarity and thump.
VOILA! Alpine head unit with NAV. Added touch screen replacement kit for HVAC controls. Replaced all 4 door speakers with Alpine 5x7. factory amp stays to power surround speakers in front and back. And the factory sub on rear deck. Then 2 10" subs custom fitted in trunk.
