Hey guys Thinking my next upgrade to my truck will be a better sound system. I currently have the factory bose, and don't get me wrong, the things great....but I think an amp and a sub or two would be AWESOME. Now...for the questions Can I even do an upgrade? A friend of mine had an upgraded stereo from the factory (don't think it was bose) in his oldsmobile...I think it was an 02 or 03? Can't remember, but he wasn't able to do an upgrade because the vehicle was already amped and stuff from the factory. Now, I know next to nothing about audio or electronics...is this possible? Next - Im assuming I will have to swap out my stock interface, correct? Will this affect my steering wheel controls? If so is there some sort of adapter to make them work? Which ones are good...I don't need the fancy touch screen blah blah blah, but I also don't want the cheap pop out kind? What's the best guys? Amp and sub wise.... I dont know anything about amps....nothing. I was thinking two 10's or two 12's...?? Who's the best for not an outrageous price? I was looking at the JL audio stealth box...and I REALLY like that. Perfect fit right under the seat...hides away can get it close to factory carpet, leaves room for the one set to fold..only problem...700 bucks for the stupid thing. That's not including an amp or the deck..or the installation because I know I wont be doing any of the wiring. Who makes the best stuff....whats the best way to do it guys? I want everything under the back seat..preferably like the stealthbox. HELP! Thanks guys...I know this is long!
