well i finally got another s2.600.2 (600 by 1 at 4 ohms) after waiting 13 days; buty anyways as some might know i have two older type r 10's(300 rms)already funning off of one.. should i just get the new model for the second amp (dual 2 ohm version that is)?
No.. you would most likely get cancelation.. they may be the same sub.. but the newer one I'd imagine will have different TS specs.. I'd look into selling your old Type Rs and investing in two of the new ones.. or some different subs altogether. Depends on your pref.
