Hi,
i have a e53 without DSP and as you probably know, the sound is lame. I would like to upgrade and i found the following solutions: 1. upgrade to DSP. Is it difficult/expensive? 2. installing an amplifier and a subwoofer. is this difficult? i have to link all the speakers to this amplyfier? I do not thin ktaht i have an amplifier right now. Any suggestions are more than welcomed. 10x |
