I installed a pair of replacements today that are working perfect so far. These replaced the front 6.5" 2.2 OHM door speakers on my 2001 Sienna. I searched on Amazon.com and found a 6.5" Sony component set for $79. I just checked and the price is up to $101. Go figure... Model #: Sony XSGTX1620S
They fit the existing mounting holes perfectly, no modification required at all. I didn't install the tweeters, the 6.5" V shaped speaker covers, nor the 2 crossovers that come with the set. My biggest concern was replacing 2.2. OHM speakers with 4 OHM but so far it sounds amazing. I blasted the s*(T out of it on the way back home tonight. I think my blown out speaker situation is finally over.
