Sounds like you performed a great install.
I contemplated 6x9s in the front but didn't want to do all that work. I ended up installing Infinity reference 5-1/4 in the door (one so far though). I ran new wire from the radio to all speaker locations. It doesn't take too long to do at the front... just use a piece of wire hanger to punch through the rubber grommet with the wires taped to the other end and pull through under dashboard. I kept the bose enclosure and used a jigsaw to widen the hole since the new speakers had a slightly larger diameter. I then cut the back off the bose box so there was no enclosure...(the speakers are free air). Installed the component tweeters on the upslope of the door molding. I bought a Nissan wire harness from Best buy...Poineer double-din radio with cd player and cassette purchased off the web. The rear has Kenwood 6x9s and I installed an amplifier under the rear deck where it's hidden. In the trunk is a double-ended 8" bazooka tube... I installed it with quick disconnect plugs and fabricated a handle so it can be removed when I take those big luggage trips to the airport. I plan to install a small 60W alpine amplifier that I've had forever somewhere up front under the dash.. This will be used to power the front speakers.
I suggest running good speaker wires for the fronts since the stock wires were feeble...mostly because the signal was being amplified at the speakers instead of from the source so all they needed was light gauge. I dont think you would have touched the clock connections since it's above the radio but it doesnt hurt to check (if fuses are good).
Now you need to get the "bose" comment from down below your posts!
Good riddance I say!!!
