well i think they are strapable just like the 2500d but if ur talkin about the ol skool models i think they are not strapable, if u need 5000 rms at 1 ohm u can get a cheaper amp that will be just like it, a sound stream 6k rms, a earthquaker, atomic 5000.1
I have a d5000, How would I be able to find out if its strappable? Also what kind of electrical upgrade do you have or are you planning on getting. 5000rms is a huge draw specailly with those amps. And what are you powering?
