Well, I have been looming into this a fair bit recently.. I have been trying to find some decent speakers to put in my ute.

I am planning on making my own kick panels that have a small rise where the speaker is to create a bit more room, and the speakers will be put up higher up on the kick panel to hide them a bit more and also to stop clearance issues with the body and the accelerator pedal on the drivers side.. and then having just 6" speakers in there.

I have also decided to make up my own mounting board that goes across the bottom of the rear firewall. Its going to go from the bottom of the angled piece and to the floor so that it allows me to have enough room to fit a pair of 6" x 9" speakers in (1 on each side..)

and I was thinking if I can find a speaker that is small enough to br able to fit on the inside of the b-pillar. I have been looking at this and (I think..) a 4" will fit up higher (above the seat belt..) and still fit in the factory hole thats already in the pillar.

All the speaker grilles will be painted black to help hide them a bit better..

And I had a thought about the head unit.. Instead of fitting it to the glovebox and taking up all your space, fit it in the back part of the centre console and just hook up an IPod and use it to play the music.. That way you still have the room left in the glovebox, and a small amount of room left in the centre console.. aswell as just having the original radio player in the dash to give it that 'retro' look..

As you can tell, I have been racking my brain over this.. lol hahah I just don't want to spend heaps of money on speakers that won't fit and will show themselves and ruin the look I am going for..
