[QUOTE="SourceUp, post: 8288877, member: 662074"] Hi guys, i have a Infinity Reference 1600A amp Specs Reference Series Class D Monoblock Amplifier RMS Power Rating: 4 ohms: 400 watts x 1 chan. 2 ohms: 600 watts x 1 chan. Max Power Output: 894 watts x 1 chan. Tuned Bass EQ (0-6 dB bass boost at 50 Hz) Variable low-pass filter (32-320 Hz, 12 dB/octave) My question is what kinda of sub do i need exactly, my box is of a 15" one. So if i get a 2 ohm the RMS does not have to exceed 600W, right? and if its 4 ohm the RMS does not have to exceed 400W, am i correct? Thank you in advance, also what is better 2 ohm of 600RMS or 4ohm of 400RMS? EDIT: also what does dual 2 ohm mean? and what has lower bass: Frequency response: 20-250 Hz SPL (dB @ 1w/1m): 86 dB or Frequency response: 23-400 Hz Sensitivity: 96 dB [/QUOTE]
