General Specifications

Equalizer Bands
The number of graphic or parametric equalizer bands the receiver has. The better the EQ, the more likely you will be able to "tweak" your sounds to your desire.
30 band
Speaker Level Inputs
Speaker level inputs are commonly referred to as high-level inputs and vice versa. This input type allows you to get your audio signal directly from the speaker wire in your vehicle, instead of using RCA cables. The advantage of this is factory integration, as most stock radios do not have RCA outputs to run amplifiers.
Total Number of Inputs
This is the total number of input connections that go into the unit.
Total Number of Outputs
This is the total number of output connections that the unit will produce.
THD (Total Harmonic Distortion)
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.
Signal-to-Noise Ratio
This spec compares the strength of the signal to the level of background noise. A higher value indicates less background noise.
96 dB
The width of the item from left to right (side-to-side) measured in inches.
The height of the item, measured from top to bottom, in inches.
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.

How do install this using a 4ch and mono amp if this thing only has one set of rca?
T-Top on Dec 11, 2015
Best Answer: If the amplifier being used doesn’t have an option for 2-channel inputs or does not have a pair of pre-outs to connect additional amplifiers, the signal from the FiX™ 82 can be split with a couple of Y-adaptors. Plug in one of the Y-adaptors into each of the Left and Right outputs. Connect both RCA’s from the split left channel into the front left and rear left channels of your amplifier and connect the split right output to the right front and right rear inputs. If a subwoofer amplifier is being used, it’s recommended to add two more Y-adaptors, one on both the Left and Right channels for the rear input signal. Connect the additional RCA cable to the inputs on your subwoofer amplifier.
