Question, if I place a speaker in the center consol, under the radio what type/brand do you recommend? I don't want to spend over 100. 00 for a simgle speaker. Also I would like to know what brand? I am currently using a soundstream 305S amp. I am going to upgrade to a MTX 5 channel amp and a mono channel mtx to drive 2 10's which are mtx's as well. Please advise
