Well, my Polk db351 3.5" dash speakers arrived today. Of course I had to install them immediately. The whole process took me a little over 2 hours to do. I could probably re-do it in half the time now!
The dash speaker grates simply pop off. I used a flat head screwdriver and pried them up to get my fingers under them and pulled them off. I used a 10mm socket to loosen the factory mounting bolts and removed the speakers by unhooking them from the harness.
Before I did any wiring, I made the necessary trimming to the stock mounting locations. It wasn't too bad once I busted out the dremel. I removed all of the factory female metal mounting brackets from the stock locations because I wasn't going to be able to re-use them. I had to grind some plastic off of the bottom of the driver side factory grille that snaps over the speakers because the tweeter kept hitting. There is more room on the passenger side and in turn it was easier to modify. Once I had my speakers mocked up and I had the necessary clearances, I moved on to the wiring.
I then un-soldered the factory harness from the factory speakers. I soldered the factory harness to my new speakers, soldering a Polk supplied low frequency filter inline on the positive lead.
Now, I simply plugged the factory wiring harness newly soldered onto my speaker back into the harness in the truck. I fired up my radio to make sure they worked, and then screwed them into place. I snapped the speaker grilles back into place and enjoyed.
These speakers are running off of my head unit at a rated 22w rms. I only listed to 2 or 3 songs, but they are much louder & clearer. I lost the loud screeching treble that my stock speakers were so willing to provide at higher volumes.
I purchased them from Sonic Electronix on ebay for 37.50. They sell them on their website for 44.99, so I got them through ebay. Shipping rate was the same for both. I went with the Polk db's because all my door speakers are Polk db series and I am very pleased with them. Now for some pics:
