In exclusive partnership with top-tier modification house Parts ConneXion, Underwood HiFi is proud to offer the following carefully tested, factory-authorized performance enhancement packages for Outlaw amplifiers.


By virtue of selling consumer-direct, we can offer these super-charged, brand-new 200/300w into 8/4 ohms models for a better price than the same modifications would cost retro-fitted - though we offer that, too. Perfect for RCA/XLR or vertical/ horizontal biamp operation and full-range speakers.
