I have this amp connected to 2 15”VCW 15’s with big 3,3600 Energie battery & Mechman240. At first I had it on an audiopipe dealer line 2k and it sounded great but just not enough. So, I ordered this lil monster and boom!!! My subs came to life! Just make sure to set your gains and make sure you’re not clipping the subs and you will be very satisfied.
