I'm currently running 2 of the sundowns sld-10's in a jl audio 2005 Tacoma prefab box. One of the sundowns fried so I'm hoping to upgrade. I'm looking at the dd sl610's. I'll be running them at 1200rms @ 1ohm load. Would the dd's be a upgrade? The sundowns were better then the jl's that came in the prefab Tacoma box as it is.
