Need Stereo Help, new and stumped Options

[TrdKing]

Ok I went and picked up some 6 1/2" speakers for my celica and came home only to find out about the front being 6 3/4" and the backs 5 1/2"?

What do people actually put in for speakers? size? power? brand?

I bought a decent deck and was just looking for some cheap speakers that sound good to go in with the deck.

After looking at the back speakers is there anyway to actually fit an aftermarket speaker in there they seem to mold to the plastic mounting piece. Could I buy a 5 1/2" and put that in their? Will it require any modification?

I read through the front 6 3/4" inch front speaker install and was wondering is that what everyone is doing? Is it that hard? What about the back?

I bought some Performance Teknique speakers for 150 CAD but they are all 6 1/2"
but heard they arent that great. I am going to bring them back and probably get some panasonic speakers to go with the panasonic deck.

Please help me out I dont want to buy crappy stereo stuff and I would prefer something I can put in myself.

Don't go out a buy speaker mounts, just draw around the original speaker onto some 8mm ply/mdf and make your own speaker mounts to fill the gap you have left. I did this with mine in the front and rear and have 6.5" speakers all round without have to trim any door pannels.

Head - Caska DVD/TV/AUX/TUNER 4x50W, 4 PRE OUT,
Front - Infinity Reference 6.5" componants
Rear - Velocity (Blaupunkt) 6.5" 2 way
Amp - Kicker 404
Sub - Alpine S Type 10"

Its not the most expensive setup in the world but its loud enough to make your ears ring. Just dont spend a lot of money on one thing and skimp on others, it won't sound right, better to spend a moderate amount across the whole range
