This question has been asked quite a few times here. I have read many threads going back quite a few years and the answers are few and cloudy. I have noticed how opinionated folks are here, yet they end with no opinion. Please, dont think of me as a jerk for calling you opinonated. There is nothing wrong with having strong opinions when it is something you know.
I realize that a lot of people here are going to spend $700.00 on a 4 channel amp, probally never even look at $300.00 models. However, there are a lot of $300.00 amps. From what I have seen the largest percent of amps are in this range. May be why this is such a hard question to answer. I am having a real hard time making up my mind. I only want to do this once. I want the amp to last and sound good, I dont care about loud. As long as it is loud enough to keep me awake during a three hour drive home. The amp will be used to power one 10" woofer and a set of front componants in a CRV. I will run rear coaxials off the head unit. I have been trying to make up my mind for a week now and the only clear answer I have got is from Quackhead. He recomended the AQ 120.4, so far that is at the top of the list.
So straight up tell us all what NEW 4 channel amp you would get if you had a budget of $300.00. Please dont call out someone for there opinion. There seems to be a lot here looking for the same thing, so you will be helping many with your answer.
