need your opinion on a number of brands

as a car audio installer,i was basiscally wanting to know what the online public had to say about these lower line brands other than (visonik and digital audio)..someone had mentioned the spl series III amps are good,and they are right about that when it comes to a good bang for you buck....someone else said i must not be into sound quality if im using aura sound and audiobahn products(that tells me they have no idea what they are talking about,or have never used there products)....as for panasonic headunits,ive had nothing but good luck with them....

have you ever heard the expression,you cant make chicken salad out of chicken sh*t?well if you have the right enclosure you can make almost anything sound good,just ask toby,he makes his own speakers and boxes....

I have been using the top of the line panasonic....another great brand is(AMPLE AUDIO)there speakers are glassfiber woven cones,and the amps put out a hell of a bang for the money....good clean sound....
