I opted for the 8w3v0. My audio guy said the stock mounting for the amp should be fine, but to keep an eye on it. He said if it seems to be getting too hot, I could mount a cooling fan to the amp. So far, I've had no issues. That may be because I went with the 8w3v0 instead of the 8w3v2. He said I really would be wasting money on the v2, because it really needs more power than the amp could cleanly produce. I took his word on it, because the v2 was 2x the price of the v0. Plus, I didn't have to bridge it...just swapped out the crap Kenwood. BIG difference.
