Okay. Here is the story thus far. I went to the dealership and talked to someone in the service department. He gave my car the once over, but admitted that the system sounded weak. Then we went to another Limited and lo and behold, the system sucked too. So it seems like we are stucked with this issue. The good news: He put me on to this site- Hyundai Service Website
. You have to register and pick the Hyundai you have. For us it will be the Elantra(ud). Go to detail search. I put the word amplifier and what it did was gave me detailed location of where it was at in the car. I also found out exactly where the wiring is, but the most interesting thing I found was that the max output was 360 watts, but the RATED watts of the amp was 200!!!! So are we getting shorted on the power? idk, but I will print out the page and bring it to Best Buy to see what they say.
The bottom line is that I THINK that we can upgrade the system, with this information from this website. The diagram is there, so granted we may have to come out of pocket a bit, but anything is better than what is in there. now
I will report back Monday or Tuesday when I go to Best Buy
