Okay, I just want to start off by saying I have been using these forums for a while and just now decided to join! but anyway, I have a 2001 Cadillac catera (50k miles) with the Bose sound system. I want to hook up a new sound system. I've been looking and found an ideal system for me. Here's the link, http://www.sonicelectronix.com/item_....html?from=857 . Anyway, I want to know 2 things. 1, will I need to get a new stereo (I really like the Stock stereo though). And 2, if I hook up this system, will I need new speakers? I think I read somewhere the speakers won't play without the stock stereo. Please help!
