My xx-hercules came to me when i bought it BNIB with a brok'd LED logo and a fried RCA jack.
i sent it into CIA engineering, it took them 3 months to get the amp back to me. When i got it back, the LED logo didnt work, and the amp worked for a whole 15 minutes (not my fault either, i tested 2 other amps on the same wiring, both worked) before it quit a second time.
I sent the amp back to them (they did pay for shipping and whatnot though). This time i figured it owuld take forever, so i sent it in a few weeks befor ei left for commercial fishing this last summer. I get back home 2 months later and nothing. So, i call them, and they said "they were waiting on parts". another 2 months goes by, and i finally got it back, broken. I eventually freaked anf raised hell, and hifonics ended up swapping me for a new 2607, which i use now.
CIA = never again
