Hey guys I'm back with a new ride! So I've been installing new Polk audio speakers all around. Does anybody on here know where the stock crossovers are for the non Bose system in the 04 cab? I put the speakers in without the crossovers but I can't sleep at night knowing I didn't put them in... and second, for the speakers on the dash, I've heard they're tweets or they're mid/ full ranges, and they have 4 wires going into the speaker itself. It's only a 1inch. So if I can wire in tweeters how would it be done with 4 wires? I'm counting on you guys because I haven't gotten any help from anyone! Please lmk what y'all think!! Thanks all!
