Any ideas where I can pick up a subwoofer for my mega? I would prefer a factory model but might go with an aftermarket if a good fit. It would have to fit under the rear seats . The radio i have is the factory with 6 cd changer and nav. I like the sound now but think a sub would put it right at the top. I do not think there is a harness for the sub in the back. Year is 07 and it is an 1500 laramie if that is important
Check out JL audio or Alpine for subs and amps, Sub Zero for boxes. I've seen some other links to boxes built specific for your truck posted here in the Audio section. I need to find one that will fit under my back seat as well.
You will need an amp and some wire. You can get a signal off your rear speaker to patch in to the sub. One item that comes in handy is getting an amp that has a remote gain control. That way, you can tweak the gain from the front depending on your listening mood.
Sorry I can't be of more help...I'm a bit of an audio noob myself!!!
