I just got my Pioneer Rev's from Fedex today, and got them installed. I had to cut the stock Honda Accord baffle to allow for more mounting depth, but it ended up working well as a 1/2" or so, spacer. Here's a link if you are not familiar with the Rev's:
I'm powering them with this:
and these are the speakers I used to have in my doors:
The amp does 65W x 2 @ 4 ohms. I didn't have time to set the gains with a multimeter yet, but I'll do it this weekend. Right now the gain is about 1/3 of the way up. When one of my Infinity's went out after only a few months of use I decided to get these mostly on recommendations here. I had a quick audition of them running full range in the wall at Circuit City and I liked them. I also figured going from the bottom of one company's line up to the top of another company's should sound a bit better. They ended up only costing about $15 more than the Infinity's (I bought both from millionbuy).
When I got these in and turned them up I was really blown away. They sound great! They get REALLY loud and are clear with no distortion. The highs are WAY less harsh than the Inifity's (that's mostly what I didn't like about them, I always had them EQ'ed down). With all my EQ settings on flat and the sub really pumping these things totally kept up (rest of my setup is in my sig). Before the subs would really overpower everything, but now it actually balances out (overall = way louder).
Hope that helps everyone! I have some angled speaker rings (1/8" thick to 3/4" thick) that I'm going to try to aim these more upwards and hopefully raise the soundstage, but right now I'm really happy with them, and I think they're a safe bet for anyone looking for good coaxials under $100/pair
