With all the adjustments possible, the 3Sixty.2 makes fine tuning your car simple and easy. Files with particular settings may be saved, or even shared with others via the Internet. You can make individual sound quality files for different types of listening material or for different soundstage effects in your vehicle.
Lab MeasurementsAll signal processors are a great place for alternator noise to enter, but the Rockford unit has a very good output impedance at below 300 ohms, so ground loops should not be an issue. Input and output voltages were also very good - this thing will take any OEM amplifier on its high-level inputs easily and will accept over 20 volts on the RCA inputs as well. Maximum output voltage is very good at 6.6Vrms.

During testing, two published specs were different than my measured data. The first, the advertised -24dB crossover slope, actually measured -21dB/oct, but that's relatively insignificant (see Graph 1). The S/N ratio is published at -100dBA, but measured at -83dBA. The difference is due to the way we measure: The published number is achievable, but only in a best-case scenario.
In the world of car audio, lots of ideas come and go. Some are good enough to stick and become accepted practice or a common feature. For example, I can easily remember when amps did not have crossovers and source units did not have separate subwoofer outputs. But, as our industry evolves and changes, we are constantly forced to meet new challenges and invent solutions to new and sometimes complex problems.

One of the biggest challenges the industry faces currently is how to continue to improve and add aftermarket components to the factory stereo system. As we all know, since the widespread adoption of factory CD players, the OEM systems have gotten a little better every year. Manufacturers have integrated other features into audio components, making consumers think twice about their replacement.
I think the Rockford Fosgate 3Sixty.2 Interactive Signal Processor is one of those products that will be a trendsetter. The name hints at its multi-use functionality, but as I discovered, it couldn't begin to describe the power and flexibility the 3Sixty.2 offers.
