I know what you meen about tight budget I aint got [censored] for money so I just shoped around and bought my local audio stores specials haha, took a risk and went with a new brand of amp(Concept 350watts for cheap) its a really nice am I have had no problems with it actually its got alot of great features in case I want to use it to run door speakers then I have a 12" rockford HE(sealed box), and I have 5.25" alpine components left over from my last car which are powered buy a 200 watt MTX amp built in cross over so I turned of the low freq so I got nice crisp sound with no distortion and I have a really nice amount of bass pounding through from the trunk and I think I didnt even spend over 750 dollars for all this.
