Hey all,

I have a couple questions, maybe listed as two part questions. I am installing an aftermarket radio and I have gotten all the wiring in and can get the radio on and performing but I can not get any sound. I tested with my multi meter, coming out of the radio, up to the connections and then the backside of the connections and I am getting power through. My first question I guess, Is there a way to bench test the amp while it is still under the dash, so that I do not have to tear my truck apart to find out that it is good or bad? Next question, if this is not feasable, Can I just bypass the amp connecting the existing wiring to the new system or will this mess up the speakers? Thanks for any suggestions I may get.
