E60 Sound system upgrade, any advice?
I have an 06 530i and I want more out of my audio system. So far I plan up upgrading my amp and the speakers under the seats. I want to install Earthquake SWS-8 2ohm's under the seats and I have a forum on how to install them so that isn't what intimidates me. I want to replace the amp with a blaupunkt php-555, however they are discontinued. As far as I know those are the only plug n play amps made to work with bmw oem audio systems. I can't find one anywhere new or used.
Does anyone know of another amplifier that can be installed with minimal complications? Please and thanks!
