Hi all I am a newb here and I have a hummer h2. It has a factory 11 speaker bose system. Its sounds ok a bit worn out from previous owner and it has no sat radio. So i made the mistake of ordering a sat radio and a gmos 100 harness and I installed it. Sounds even worse and I hate the head unit i purchased. What I want to do is either install a system or have one installed that is a bit louder and crisper than the factory unit but I would like to retain the stock speaker placements as much as possible. I am not into any super heavy bass just a slightly louder crisper sound and a very slight increase in base. I have no idea where to start all the information and systems out there are overwhelming. And if someone could steer me in the right direction on where to start. I have been thinking about going to the local installer which is a cartronix store and they have some good reviews but somehow going in there green like I am that they will take advantage of me. Any help would be appreciated. I am a super newb and not afraid to admit I know nothing.
