I've got myself 2 new sets of pioneer speakers to replace the dash and door speakers. I've already done the dash ones . I want to replace the cable too with better stuff I got and I've a new iso plug ready to wire up.

My question is about the wiring. Are the dash and door speakers wiring together? Ie are the right dash and right door speakers just split and both connected to the front right on the iso plug? When I mess with balance and fade they both seem to be on front right so that what I'm thinking.

Did you find it out? What speaker model is it? Do you think it also fits in Doblo 263?

Havn't replaced the wiring yet but did swap the door speakers.

Those are the ones I replaced the factory speakers with. Good fit.

17cm speakers were fitted without modification? I thought the OEM are 10cm.

Is the actual dimension of the mounting hole known to anyone?
