Hi, I was wondering what I should do in this situation: On kijiji someone advertised the v12 alpine amp ad being an mrv1000 v12 alpine amp, I bought the amp for $80 and I fully believe it is worth at least this much, but I still wanted my money back. The guy who sold it to me refused and instead offered a trade up of the v12 for the m50. What's better? He will test it in front of me to prove it works, but after he lied about the previous amp should I give him the second chance? Is it worth the risk? I need to power 2 alpine 10 VR subs. I have two alpine type-s 5x7's that I could wire in too, if the ohms make a difference.
