i have a complete system for a 4 door crew cab. this system will only work for the 04-08 crew cab f150. the box and sub comes from JL audio. it is a jl stealth box with a 10 inch JL W3v2. the box is made by JL to fit under the back bench with the sub down firing. the box is carpeted dark gray so itll match the darker interior. the amp to power the sub is a rockford fosgate p250. it is a 2 channel 1000 watt amp that is used to power the subwoofer. for the headunit i have a eclipse cd4000. it is bluetooth ready and has complete subwoofer controls built in. everything is in perfect condition and the system sounds and looks clean. asking $500

 

have fun with this one NGM!
