Hey there everyone! So I’ve got an 87 B II that I’ve been restoring for s few years now, and I’m at the point that I’m putting in a whole new stereo system and could use some advise! So i ordered (2) new 3.5” 90watt speakers for the dash. Also ordered (2) 5”x 7” (I installed the XLT rear side panels with the center mount speakers) 500watt Max 3way coaxial speakers. Also have (1) 10” Rockford Fos. Punch P1 300 Watt peak subwoofer in a sealed slim box, shared with (2) 1” tweeters. I have an old radio HU that I had laying around but I’m thinking about buying a new one. So my question is how I should wire all these up, if anyone can advise me to get any crossovers/ speaker amps/ etc. I had already run new wiring for my rear & dash speakers, opposed to the old degrading stock wires, and new subwoofer cables. Any advice or input will be very appreciated!
