using a SSL 1200w monblock to power 2 of these. they let me know where every loose bolt on my car is, they shake it so much lol. the vibrations woke my nextdoor neighbor when i turned them on for the first time. can’t wait to hear them after they’ve loosened up a bit.they’re also amazing for just puting music through them on high pass (how ive been using them), not just base, cause it comes with a high an low pass filter. and the remote bass control is a very niffty thing to have. glad i hooked it up.
