What amp would i need for two of these? a 2400 watt amp?
Abel K on Sep 3, 2015
Best Answer: The Pioneer GM-D8601 will work perfect. This amp will put out 500w X 1 @ 2ohms. So if you have the option of only running one wire from the box, wire the subs together in series and wire the voice coils in parallel (each sub then running 1ohm a piece and back up to 2ohm for the set. If you have the option of running wires for each sub out of the box, then wire the voice coils in series. This amp features two speaker terminals so you can Holm them up to their own terminals, and being as it is a monoblock amp, the impedance well dumb back down to 2ohm total.

Can I wire 2 Rockford Fostgate R2D2-12 (4 Ohm) subwoofers to this amp in a 2 Ohm configuration so each sub will be hitting 250 Watts?

Best Answer: This would be perfect, and will do absolutely no harm to the subs as it is split. In a system like this it is best to match your RMS rather than go above it which will not only limit your power capabilities but also over stress your amp due to running 100% all the time pending the type of music. It is easier to tune down rather than overrun everything else to meet power requirements...

what box would work best for 2 of these subs?
Alec L on Nov 23, 2014
Best Answer: Hello Alec,

The Atrend 12DQV makes for as close to a Perfect match as you are going to get , from a Pre-Fab. The subs ask for 1.79 cubic feet PER SUB, and the 12DQV is providing 1.80 cubic feet (per chamber) BEFORE displacement. Once the sub is loaded, the Volume will fall well within the 1.79 that the sub(s) require.
