Thank you for the nice video, I just installed the TS-D12D4 with the GM-D8701, connected in series at 8 ohm, I'm concerned about sound quality more than spl, What do you think about connecting in parallel @ 4 ohm would be better ? thanks again
You missed the main thing. That is sensitivity. The pioneer's Champion Series Only good with sensitivity ratings others can only handle high power, can't output more loudness....
I don’t think pioneer can keep up with the “new breed” of companies. DD, Gately, Skar, and many others make higher quality. For same price or just a little bit more.
