Ok my situation is this:

I have a friend who wants to sell me a new Hifonics (http://www.nissanforums.com/#) amp at a low price (around $120).
I have another person who wants to sell me a Kenwood (http://www.nissanforums.com/#) amp at another great price (110).

I am planning on buying a single 12" Alpine Type-R sub and box, I just need the amp to go with it. I dont know much about them but I do know that I am more interested in Quality than anything.

Any suggestions?????
