I took out my back seats and parcel looking to install my Kenwood 7x10's. I scratched my head for 1/2 hour and then told myself, this can't be done..and even if I did get them in, the magnet would be too close to the battery for my liking!
So......I installed them on the arm rests of the rear seats, just behind the front seats where the seat belt are. Took me about 40 mins to cut the right shape to fit the 1st speaker in. But the 2nd speaker was a breeze since I knew what to cut and how much to cut. I cut it with an angle grinder and made a bit of a mess. So if you plan to do it, cover the interior fabrics and have a vacuum cleaner handy!!! WARNING: DO NOT CUT ANY METAL BELONGING TO THE PILLAR STRUCTURE!!!! this will jeopardise the integrity of the car body.
But in the end, it was sure well worth it!!!!!! The Kenwoods pump out solid bass..bloody unreal. And the sight of them next to the armrests are bloody unique!!!
As for the rear crappy factory speakers, they make good door stops...hahaha..anyway, I may buy some 5.25" speakers as a replacement. This means my car will be a 6 speaker system...Oh yeah!
Personally, I strongly recommend the rear parcel shelf speakers being replaced or removed, and having them next to the arm rest. By doing this, you leave heaps of room for a sub (s) and amp in the boot. And if the sub (s) go in, then the original holes for the speakers in the parcel shelf can act as a duct for bass to flow into the cabin - since the rear seats are enclosed and do not fold to the boot!!! Also, as I pointed out, having the speaker magnets so close to the battery terminal is a nono!!! This also eliminates the need to mdf the parcel shelf - quite a hassle to cut and carpet!!!!
I'll try post some pics shortly. I still dun know how to use this forum fully, I am a newbie and got my R33 about a week ago (and spent the weekend doing this install)!!! :headspin: :headspin: :headspin:
