RMS Power Output The amount of continuous power that an amplifier produces is called RMS power. The higher the RMS figure, the louder and cleaner your music sounds.
Peak Power Output Tells you the maximum wattage an amplifier can deliver as a brief burst during a musical peak. The RMS figure is more significant.
Frequency Response The range of frequencies, low to high, the amp can reproduce. The standard is the range of human hearing, which is 20-20,000 Hz.
Signal to Noise Ratio Measured in decibels (dB), this spec compares the strength of the desired signal (music) to the level of background noise. A higher value indicates less background noise.
THD at Rated RMS Power The amount of change in harmonic content of the signal as it is amplified. A lower figure indicates less change and a more accurate amp. THD below 0.10% is inaudible.
Input Voltage The input voltage used to measure the power output. Can range from 12 volts to 14.4 volts.
Power at 2 Ohms This spec tells you how much more power your amp delivers when presented with a 2-ohm load. You can achieve a 2-ohm load by using two 4-ohm subs wired in parallel, or by using a 2-ohm sub.
Bridged Power The output wattage (RMS) per bridged channel.
Minimum Impedance Bridged The lowest impedance the amp is designed to handle when it is in bridged mode.
Preamp Outputs Number of RCA outputs. An RCA output lets you pass the preamp signal from your head unit to external equalizers, amplifiers, and other equipment.
Speaker Level Inputs Useful if you're adding an amp to a factory radio, or don't have enough preamp outputs on your aftermarket receiver.
Amplifier Class The type of amplifier class the amp belongs to. The most common types are Class A, Class B, Class AB, and Class D.
Passive Equalizer Allows you to fine tune your music at the preamp level with multi-band adjustability for maximum quality and control. Accepts RCA inputs from your aftermarket stereo and delivers RCA outputs for your amplifiers.
Electronic Crossover Gives the user variable adjustment with different crossover points, allowing the user to remove unwanted frequencies from different preamp lines. Example: channels A and B high-pass (80-460 Hz), channel C low-pass (50-210 Hz)
In-line crossovers Crossovers put in-line with the patch cords (RCA) feeding your amplifier. They filter out unwanted frequencies. Low-pass models let frequencies below the cut-off point through and filter out the highs. High-pass models let frequencies above the cut-off point through and filter out the lows.
Tri-Way Crossover A tri-Way crossover allows you to power a pair of stereo speakers and a subwoofer simultaneously from a Tri-Way compatible 2-channel amp. It's a cost-effective way to drive a subwoofer.
