I have read quite a bit about the 77kick10s. I noticed they are the only ones with three tabs also. I bought some cheap crap from Walmart that said they fit my jeep but they did not. It is easier to rob a bank then get walmart to take speakers back.
I would stay away from Boss. They are cheap and not good sound. Go with a better brand and you'll be much happier. Pioneer, Kicker, Alpine, JL Audio, etc.
