Thought I would post a few pics of the new speakers & solution for replacing the rubbish door subs in my 986. I had already removed the original head unit (running a Sony mechless head unit with speakers powered direct from this as fronts + rears), amplifier & replaced the dash speakers with Alpine SPG 10C2s as I was really dissapointed with the poor sound from original set up.. Being all OCD I went for Alpine SPG 17C2s (6.5") for the doors to match my dash speakers. The original subs are 13cm/5" monted in a plastic box mounted in the bottom of the door so it took a bit of thought to come up with a solution. Found a couple of threads where the enclosure had been cut open & speakers mounted into MDF which was bonded to said enclosure. I didnt like the bonded part so used the black outer ring thats held on by 6 screws as a template & spacer for my MDF sheet. Lots of fitting, removing, refitting, measuring & cutting later I ended up with a good solid (for solid read last forever as I over engineer anything I do lol) mount for the speaker pretty impressive when you consider its a 17cm speaker squeezed into a 13cm space. Really happy with the result & well worth the effort with sounds improved massivley.
So first look was hmm this isn't goint to fit might be sending them back for 13cm ones!!
Nothing a dremel can't sort out & commited at this stage!!
Lots of measuring, fitting, refitting, more fitting, more measuring & cutting later everything ready to be fitted with the oblong 6 holed plastic bit going on first then the mdf followed by speaker (enclosure has to go into door first as mdf holds some of the door membrane in place. Original sub is on the right to show size difference.
All back in using original mountings, wiring & no clearance issues (before anyone asks I did tighten the loose screws up!).
