i want to buy, a sub, and an amp for my 106. i have a £400 budget. Now i was wondering about Wattages & Ohms. If i buy, say for example. 2x 12" Kicker L7 solobarics, with a wattage each of 750Watt rms, 4ohms. Then would a 1500watt rms amp MONO D block be ok to run the both? Also would 2x 4ohm subs = a 2ohm setup? Also, as the mono D amp would only have one speaker output for one sub, how would i wire it for both the subs, or would i need a 2 channel amp? becuase i thought mono d's were better for subs, as there pure bass amps. thanks in advance. scott.
