STi: Sky Blue Subaru Leave a Comment / Audio / By Ultra Auto Sound Hatchback boom box. Door panel before focal sound deadening installed Sound deadening installed inside all doors Kinetik HC2400 to supply big power to the power hungry amplifiers. Amps mounted below floor board and hidden. Fans installed to keep the amps cool and to have air circulation. Our customer was very hands on and made his own amp board. Amp controller run upfront to fine tweak and to show amplifier voltage and temperature. Share This:FacebookTwitterEmailLike this:Like Loading... Related
