*SOLD* FS: JLAudioStealthbox10W3V3-4 Subwoofers 07-up Silverado/Sierra Crew Cab For sale is my JL Audio Stealthbox containing 2 10W3V3-4 subwoofers and a JL Audio GL1700 Monoblock Subwoofer Amp. This system fits crew cab trucks only. See link for specs. http://mobile.jlaudio.com/products_stealthbox_detail.php?fit_id=1592 The box is almost completely hidden from view and still allows for the seats to fold up and down with no issue. Retail is $849 for subs/box & $419 for the amp, before taxes. I'm selling the combo for $800 OBO (does not include shipping). I put this setup in my truck a year ago and it had impressive sound, fooling most visitors into thinking they were at least 12s. Nice hard, crisp bass for rock/country and a good deep bass for hip hop, etc. You will not find a better combo for the amount of air space inside a crew cab. Loved the sound, but sold my truck. PM me with offers.
