you will need 5.25" speakers for the doors. and yes , you will need the black plastic cradles to mount the speakers behind the concert sound panels. pretty simple to mount, i put some jl audio c2 525 coaxials with a pretty large magnet and it cleared everything. sounds awesome too , then again, ive also got two amps , jl audio 3.5's, polk audio 6x9s, 12" sub, and it all looks stock, everything is hidden, except maybe the 3.5's, they rub the top of the dash since the upper portion is kinda tall.
i cant even hear my exhaust , 3 in downpipe , test pipe, and magnaflows on a slightly beefier 4.1 block.
Do you feel you even need the 3.5's in the dash for the front sound stage?? I finally decided to put a stereo in the Bufrod myself, besides I had alot of the stuff just sitting in the garage doing nothing anyways. I bought a new 12, and 5.25 components for up front, I had the amps and a set of polk 6x9's. In my mustang I had a set of 6.5 quart mobile components in the kick panels, single 12, and those 6x9's. ran the 6x9's off the head unit for rear fill, then amped everything else. I had some 3.5's in the dash of the mustang but they did nothing but distort the sound. Probably should have put a filter on them, I just unhooked them. Sounded great! So I was kinda mimicking that system you know simple but does everything you need, and look stock, minus the HU.
thanx Jason
