starting bid is not bad but there is no way that amp was pushing 4k i think thats the bxi 2006d which means it was getting around 1900-2k..that is. if the sub was dual 2 and wired to 1 ohm
I'd make sure that's a BTL cuz my neighbor bought something similar on ebay and it ended up being an SSD. FYI that Hifonics does NOT put out no 4k watts like he states. Not sure on the model but it doesn't do 4kwatts.
If you're interested in an 18 i've got an 18" RE MT d2 that i can let go for $375 shipped. It's the 08 version with the black motor. LMK and i'll send some pics.
