Hello! I need a little "Sound Advice"! I have a 72 Blazer that is virginal when it comes to the stereo. BONE STOCK. I was not really wanting to hack my dash if I didn't have to. I found an Alpine 7502 shaft style cassette for $100, new in the box. It is 25X2 & has an RCA preout. It is the best of the shaft style decks I can find. I am wanting to run 6X9's in the bed area, and something in the doors (?) or kick panels? I would also like a sub in the back. Would this cassette be able to work with all this? I would also install an RF CD changer in the console I'm thinking. What kind of amp will I need, a 4 channel? I guess the head unit can drive the fronts? Or, I could get a 5-6 channel to run it all? Will the Q-Logic kick panels work on a First Gen? Thanks for reading, you guys ROCK.
