I have 2 sa8 v2 and also 34hz ,.75 cubes. Pushed by a dd audio m3a , they don't even heat up or anything. They take beating all day .running 1000rms each one ,but we know dd underrates their amps
Well I got 2 in a ported box at around 1.7 cubes .. I wanted to do 3 in a sealed box but had no more air space under the seat ...is this a trunk enclosure or where do u plan on putting the subs ??
