Well, yes as a matter of fact i am. While i may not be knowledgable when it comes to auto sound specifically, i have been a live sound engineer and tech for more years than i care to admit to, and work in that field to this day. It's second nature to me to know whether it's the speaker or amp thats causing a problem like this, and i know for a fact that a set of strong 6x9's with a healthy SPL will in fact do the job. All i was trying to accomplish is get opinions on using 6x9 subs in the rear from those who have done it if any because all i need is a tight low end from them and don't need much volume. I didn't need any advice on amps or anything else, but thats pretty much all i got. And then i become the ahole by trying to explain that so the conversation would get back to what i asked in the 1st place. Whatever.
