If you ever come a crosses these subs in the wild BUY IT

I had 2 of these subs let me tell you if you like loud hitting subs this sub will tingle your spine brake off your rear view mirror set off car alarms piss off your neighbors! with 1 on a 600 watt dual amp ran at 8 ohm my buddy thought I had 3 subs in the trunk it was just 1 in a 1.75 bass slammer ported box if you the only con is they don't make them any more so if you seen them in the wild pick it up you won't be disappointed the one I got left still hits as hard as when I got it
