I have just changed my old subwoofer with Image dynamics id8v3 and it works perfect. 10X times better than the stock subwoofer and 3X than kicker free air sub . It took me more than 6 hours to do the job, but it was worth it, would do it again if i have to. Now my sound system sounds like million dollar car . Everybody who is saying that you need aftermarket amp are wrong. I agree, you might want to add aftermarket amp for big boom, but in my case i dont want to do that. All i need is sql. I have changed all speakers/tweeters and it sounds awesome.

 

so your running that image sub off the stock amp? Do you have any pics of the setup? How about rattles?

 

no pictures, but i used 2 layers of dynamat, foam. the only thing rattling is seat belt tensioner, havent found solution yet.

 

see my comments in insang's post about the ID8. i'd be worried about running it in a free-air application

+1. That's not a free-air sub and needs a nice amount to be powered correctly. I'd make sure your not clipping it

 

its not clipping, manufacturer claims that is free air... my cousins friend have in his honda accord, running on his stock amp, for a year. No problems yet.
