Got a few worst buy gift cards from santa and so I'm going to upgrade the factory deck in my 90 K5. I'll need to replace all of my factory speakers also and I was wondering about the dash speakers. I used to have a 85 silverado and the stereo shop squeezed 2 speakers in the center location. I see that LMC actually sells a deal loaded with the speakers to fit in the center hole for the trucks that had the am setup. I was wondering if anyone knows where I could get a bracket to hold 2 3.5's in the middle or will I just have to fab one? I'm going to go all out while I have the dash pulled. Also, will the Infinity Kapas fit in the corner factory locations or will I have to go with the references? According to Crutchfields site nothing will fit that they sell but their info on the 88-91's is kind of sketchy. The same for the rear, will any 4x10 work or could I fit a pair of 4's back there. I'm just looking for highs.
