this seems to be more SPL related. I'm here for a spell learning alternators and power for a bit so I can attest to the lack of SQ experience.. Welcome, though. SQ involves ALOT of research but can be done for cheap if understood.
There are, however, plenty of knowledgeable people on this forum, dont be fooled by the jackasses who frequent as much.
There's also people, I think trailvoy*com or something to that extent, who deal with your vehicle in particular. A lot of the people on the forum have audio and can give you more ideas about what you can do in particular.
