Sounds amazing for a shallow mount sub

I had this installed with a Kicker 1200.1 amp and ported box behind the back seat of my F350. Bass is boomy but also has quick punch for various genres of music. Very happy.

Great sub

Really pleased with the sub I have one 12 in a sealed box and it’s more than enough for me. Great sound from a small enclosure you can’t go wrong.
