Hey guys, quick question. I have a base model 04 truck and the stock stereo sounds like ****. I had an 03 GMC sonoma SLS and that thing bumped real good for a stock stereo. My Sivy however sounds like a tin can. The deck looks the same as the one I had in my sonoma. Do the decks have different amp's inside? Is it the speakers that are ****? I was wondering if a "LS" model truck has nicer speakers than the "BASE" level or work truck level? I have a sale pending in the classified section and would like to know if I should buy these or not!
