1985 C4 Speaker Size
I've finally removed the HU and Bose speakers. Only question now is what size speakers will fit inside the door panels and the rear? Anyone else done this job that can offer any info? It looks like these speakers are 4" but I want to be sure. Also wondering if I can fit any bigger speakers in?
Edit: I did see the stickied C4 Audio FAQ thread but I'm a little confused on this part that describes the 84-89 speaker size: "84-89: 6.5" round or even 6x9 can fit in the doors. You will need a "notch" filter, set at 160 Hz, to soften the blow. According to Kale, the door acts like a resonance chamber at the frequency."
I'm pretty sure 6x9 has no chance of fitting in that door?? Someone help me from being stupid
