Just installed (2) Digital Design 2508 D4 subwoofers in a ported box. The specs of the box are as follows 43” Long/ 10.5” Deep/ 11.5 Tall and the port is 3” Long/ 6.25” Tall/ 3.5” Deep. Not sure what it’s tuned to (sorry I’m a rookie). I have the subsonic filter set at 40hz as recommended by DD for the break in period and LPF around 100~120hz. Gain is set to about halfway.
I have the subs powered by the Digital Design M1D amp. This entire setup is 2 Days old.
My question is, why isn’t the subs very loud? I’ve seen videos where the (2) 8” subs doing work. Flexing roofs, doors and all. My rear view mirror barely moves. On some songs you can’t even tell I have any subs at all! I look at the subs while music is playing and there’s barely any excursion.
Any ideas? The amps providing plenty of power for the subs so not sure what’s going on. Kind of disappointed with this setup so far and I spent some good money on it.
Hope you guys got some ideas!
Thank you in advance!!!
