The Power 1100a2 is a two-channel power amp featuring gold plated connections, switchable high- or low-pass crossovers with variable cutoff frequency, a 275-watt x 2 power rating into 4 ohms, and the classic Rockford cheese-grater from hell heatsink. Also included is a bass boost circuit with wired remote and an adjustment ambiguously marked “Phase Warp.”
PerformancePansy, wimp, or wuss are not adjectives that you’re likely to come across in descriptions of the 1100a2. However, powerhouse or current hog fit the bill quite well. Driving a 4-ohm reactive load, this beast produced nearly a kilowatt on our test bench and nearly 1400 watts driving a 4-ohm resistive load with a 14.6 V supply. (Rockford Fosgate recommends the use of large power capacitors to bolster the amplifier if you experience any problems with your stock electrical system.) This isn’t to say that you’ll be disappointed with its real-world performance. Noise floor, crosstalk, and turn on/off numbers are really low.
Connections & AdjustmentsConnections to the 1100a2 include RCA inputs and outputs, a spade-type remote turn on connector, and captive-style receptacles for speaker and power connections. Adjustments include input sensitivity for each channel, crossover mode select, crossover cutoff frequency, bass boost, and Phase Warp adjustment. The Phase Warp appears to be an all-pass delay. This might prove useful in a multi-speaker SPL setup. It would allow for close phase matching of multiple woofers. This, in theory, could allow for a higher SPL at the frequency for which they were adjusted. The limitation of this circuit is that it would only work at one frequency, and it would have to be fairly low — perhaps below 500 Hz in a car.
