Ok, after searching for hours and reading mixed points and opinions, im just gonna ask anyway...I have a 07 300 SRT, NOW, The car has the 6 disc Mp3 nav deck, with siruis and uconnect, as well as the factory alarm, which gives me SRT Option group II, But, i dont have the Subwoofer in the trunk or under the package tray, now the speakers are BA b/c i took down the cover in the trunk and looked at them, so in all im looking at 7 speakers with the three in the dash...Where is my sub??? was it forgotten??? was it possible to get Option Group II with out the Sub??? B/c i dont have it...I mean this car has everything but the SUB...What the hell??? I need some help here...i want to upgrade the system b/c honestly, it kinda sucks...my cuz has a 07 Grand Cherokee six cylinder with the BA system and it rocks, my SRT should have the same here...
