I am currently replacing the headunit in my 92 LS Legend, but I'm not getting any sound! I've tried to use an output converter, but still doesn't work. The stock Bose system runs on 2ohms, where as the aftermarkets run on 4ohms. I've heard you need to bypass the amp, but I dont really know how to do that. Is there another solution? If I really need to bypass the amp how do I go about? Thanks for reading this!
