I consider myself to be fairly serious about my mobile stereo sound systems. Provided are 3 attached photos of my stereo in the process of an upgrade (a work in progress). The existing system used one Massive Audio RS150 2 channel amplifier and one Massive Audio CA50.4 four channel amplifier. The upgrade adds another RS150 amplifier and a Massive Audio RS40.4 four channel amplifier (middle photo) - the 2 new amplifiers are sitting or resting on top of the two existing amplifiers.

My vehicle has 32 speakers in all; two 12 inch (Marathon MB12.10) sub woofers in a ported enclosure, sixteen 5.25 inch woofers and eight 1 inch silk dome tweeters (Massive Audio MK5i component sets - lower photo), two 6.5 inch woofers and two 1 inch silk dome tweeters in the front doors (Massive Audio MK6 component set), and two Massive Audio 3.5 inch coaxial speakers (RX3.5i) custom mounted in the center dash area.

All my stereo equipment was purchased from Sound Solutions. I have been a customer of Sound Solutions for over 2 decades. My forum profile labels me as a newbie, however I am not a newbie regarding car stereos. Questions about my sound system or mobile stereo sound systems in general are welcome.
