I had the POS unit that sounded awful. I bought a jvc kw-av60bt head unit, Autotek ATX6.2C 6.5-Inch Component Speakers, Pyle PL63BL 6.5-Inch 360-Watt 3-Way Speakers, Tuffy Flip-N-Lock Stereo Cover & Tray Dark Slate 2007-2010(awesome, security and extra storage), and Boss Audio BASS600 8-Inch Low Profile Amplified Subwoofer. It sounds sweet, its secure, has blue tooth (mounted the mic under the lip to the console, right above my tachometer), the flat sub is under my front seat and can shake me. It is definitely not for competition but i wanted a low cost system that sounds great to me and my passengers. Stuff the speaker boxes with poly fill. Total for all of this should run you $750-$900 installed. Good luck!
