    Inside the PG475ti

    When I was into car audio this was my favorite amplifier. It's been out of service for last couple of years so I wanted to see how it's made inside. Lost the birth sheet, but it was over 500wrms , and is considered by many as cheaper amp since it was rated at something like 18 or 24watts per channel lol.

    Rest of the system was an Alpine 7995 headunit, and image dynamics chameleon cxs62 2ohm components and two image dynamics 12 d2 dvc4 wired in stereo at 2ohm each. This was in a 94 integra hb, interior fully stripped and about 200sq.ft or so sound deadening everywhere upto the firewall from the back... would get plenty loud and sound great w/o any distortion with anything I would throw at it... then was used in my brothers s2k until he lost the 7995 faceplate and blew one of the mids.

    Anyway, some pictures. Powered it up with a bench psu.

    Cool, I have a 475 in white that I might throw in my E30. I have the matching line driver and eq as well. Cool stuff!

        Yes they did. I'm especially fond of the MS and MPS stuff. I have this bad habit of buying old school audio equipment on ebay that I always wanted but could never afford.

        Ask Blunt, I think I could open a shop out of my basement with all of the crap I have...lol.

          After my couple old cars got broken into I gave up on car audio :( I did always wanted to get a Brax with to3s or Genesis amps though... they look piece of art.
