I've been trying to find some info about Carver's adventures into car audio and can't find anything. I'll do some research into linear power.
I think you may be thinking of Phase Linear. It started as pro and home sound and then later got into car audio. They failed in the american market despite making very good products. They are still around and owned by the same parent company as Jensen (recoton) now. Their american offerings have dropped substantially with respect to quality, but they are among the best brands available in the European market. They have some innovative, but very expensive equipment, most notably, the Alliante series of subwoofers. The 12" has a mounting depth of under 3".
