Our take on the Rockford Fosgate 3SIXTY.1

Factory sound systems keep getting better, but even top-of-the line options don't always deliver the best sound possible. Unfortunately, it's not always easy to replace your factory stereo, especially if it's tied into climate controls or other critical features. Rockford Fosgate's innovative 3Sixty.1 lets you install premium amplifiers, speakers, and subwoofers without forcing you to replace your factory in-dash stereo or undertake a massive rewiring project.

Factory sound systems keep getting better, but even top-of-the line options don't always deliver the best sound possible. Unfortunately, it's not always easy to replace your factory stereo, especially if it's tied into climate controls or other critical features. Rockford Fosgate's innovative 3Sixty.1 lets you install premium amplifiers, speakers, and subwoofers without forcing you to replace your factory in-dash stereo or undertake a massive rewiring project.

The 3Sixty.1 offers six high-level and low-level inputs, plus six preamp outputs, so you can use it with anything from a simple, four-speaker setup to a high-end factory 5.1 surround-sound system. You retain use of the in-dash stereo, along with steering-wheel controls or any other special factory equipment in your car. The 3Sixty.1 also features an auxiliary input, so you can add extra sources like your iPod® to the mix.

Upgrading the sound of your factory stereo
You hook up the 3Sixty.1 by connecting your car's speaker wires to its high-level inputs, and your amps to the 5-volt preamp outputs. You'll also need to make power and ground connections.

Sound adjustments are made with a wireless Bluetooth® connection. You'll need a laptop computer running Windows® or a Windows CE ® or Palm® device (sold separately). The package includes the software, which lets you adjust the sound wirelessly from anywhere in the car. This lets you mount the 3Sixty.1 in any convenient, out-of-the-way spot.

The 3Sixty.1 initially sets a flat equalization curve, which eliminates preset tone curves that can sound terrible through external amps. You can then tweak the adjustable 15-band equalizer to compensate for deficiencies in your factory stereo's sound processing and the acoustics in your vehicle. When you're done, you'll be able to see a before-and-after comparison of your system's sound quality on your Palm device. A handy dash-mountable source selector and volume knob round out this impressive package.

Brand-name stereos, too.
Of course, it's not just factory stereos that can benefit from the 3Sixty.1 — you can also use it with a brand-name aftermarket stereo. It allows you to add an auxiliary input and more amps than your stereo would normally be able to handle.

Does great for me

tripps1175 from Gulfport, Ms on 6/13/2008

I have had this unit for 2 yrs now... Installed new speakers plus subs n amps. Keep factory head unit w/ nav/6 disc changer. This unit i was skeptical needing it, but listening to a friends unit which was almost exactly same as mine for speakers, type of vehicle, mine was far more superior than his. He was like wow, his sounded terrible n he spent more money for basically the same speakers, subs, n amp. Lets just say he went n got the .1 installed n seems happy now. This unit has been running nonstop for two yrs, long trips, n is great. Not sure what probs peeps been having, but no probs here. Would like the .2, but not for the money. Dodge 2500 quad cab truck, is great, thanks Fosgate.



Pretty cool

Sam from Miami, Fl on 5/4/2008

I loved using this, very cool when operating it by a palm, didnt have noise like the others said, worked perfect. I would buy again, for the .2 but way to expensive.



Noisy & Bluetooth Inop = Sent Back

Thomas from New Jersey on 1/10/2008

Crutchfield Customer Review (What's this?)

I would not recommend this product at this time, which is hard for me to say because I have (had) a lot of brand loyalty to Rockford Fosgate going back about 20 years. Just like another reviewer, I found this device to be a source of noise. Also, the bluetooth capability was intermittent at first, then went completely inop and the device was defective and was returned (onc ethe bluetooth funcationality dies, the device is not configurable). I was not using this for OEM integration, and was really just using it as a glorified EQ. I will replace this unit with an industry proven 6 channel trunk mounted EQ. If I was doing an OEM integration, I would consider this product but would wait until it matures a bit more and is proven to be long lasting and noise free.



It is a good starter investment

larry from Oxonhill Md on 6/12/2007

Crutchfield Customer Review (What's this?)

This is a decent processor however on this version they should have worked on feedback that it allows to come through. I have this gadget installed into a Cadillac SLS Seville and it serves its' purpose 100%.<BR>The fact of having to use a bluetooth remote system makes it worth the bux. I need to upgrade to the 3sixty.2 series ASAP! The 3 sixty.1 is very limited in functions especially running bass frequencies so, with that being said I recommend for the start this gadget.



lots of noise

Dean from dallas tx on 3/6/2007

After installing the oem radio has engine noise. I use the aux input and it sounds great. I have tried to work with Rockford Fosgate and they acknowledge that there is a problem working with oem headunits. Kinda funny since they say that it is for oem integration. The 360.1 is installed in a 1995 S-10 with factory radio/cd. With the 360.1 installed you can't even listen to the radio/cd there is too much noise. You cannot tune the AUX port on this device which makes absoluteley no sense. Rockford support is giving it their best try to solve the problem. I don't know if the problem is with all oem radio's but it does affect mine. The tuning updates are very slow and the remote is very inconsistent when makeing adjustments. Sometimes it works and sometimes it doesn't. No response from Rockford on that problem. Hopefully they will come out with a firmware update to address these problems and add tuning to aux port.




Hands-on research

Inputs, Outputs, and Controls
Manual Correction


Product Overview: The Rockford Fosgate 3Sixty.1 is a signal processor with equalization for six channels; front left and right, rear left and right, center, and subwoofer. It has six input channels, both line level and speaker level, so it can be used with almost any head unit, factory or after market. There is also an auxiliary input so you can add another source, even if your factory radio has no input available. Setup of the 3Sixty.1 is done with a PDA using the Palm operating system, OS V 5.0 or higher. The PDA is necessary and is not included.

PDA Compatibility: The PDA must use the Palm operating system. The control software to load onto your PDA is included with the 3Sixty.1. These minimum requirements are necessary:

  • Palm OS V 5.0 or higher
  • Bluetooth communication
  • 320 x 320 display
  • 16-bit color resolution
  • Current compatible PDAs include (but are not limited to):
    • PalmOne Tungsten T5
    • PalmOne Tungsten E2
    • PalmOne Treo 650
    • PalmOne Zire 72
    • Sony PEG-NZ90
    • Sony PEG-UX40
    • Sony PEG-UX-50
    • Tapwave Zodiac I
    • Tapwave Zodiac 2

OEM Integration: This feature allows integration with a factory radio and amplifier, if present. Many OEM audio systems are tuned (equalized) for the factory amplifier and speakers, and to correct for the sonic characteristics of the specific car. The 3Sixty.1 uses the included setup disc and built-in equalizer to reverse this factory equalization and allow smoother integration with your higher quality aftermarket amplifiers and speakers.

Inputs: Either speaker level inputs or line level RCA inputs can be used. There are 6 input channels corresponding to the six output channels. If your existing radio has six output channels, use them all, if not, use what you have. The 3Sixty.1 will output all six channels with as few as two input channels.

Auxiliary Input: There are left and right RCA inputs to add an auxiliary source unit, satellite radio, DVD system, etc.

Equalizer: The built-in equalizer allows you to modify the sound to suit your taste. The front channels have a 5-band equalizer (EQ), the center and rear channels have a 4-band EQ, and the sub channel has a 2-band EQ.

Remote: The included wired remote has one rotary knob and the 3Sixty.1 can be programmed so it controls either the main volume or the subwoofer volume. Pushing the knob enters or exits the auxiliary input mode. The remote can be mounted in a variety of locations. The module's case can be removed and positioned with the mounting bracket above or below the module. Without the case the module can be flush mounted in your vehicle's dash (requires a 2" x 7/8" cutout with a maximum panel thickness of 3/8"). The wired remote (in its casing) is 2.292" wide, 1.196" tall and 1.491" deep (2.606" deep including the knob and cable connection). The included cable is 16.25' long.

Signal Sensing: If your head unit has no remote turn on output, the 3Sixty.1 will sense an audio input signal and turn on automatically. In this case the function of the remote terminal can be reprogrammed to send a 12 volt output to turn on your amplifier.

Manual Correction

Power Supply: The early printings of the 3Sixty.1 manual instruct you to connect the 12 volt power to a switched power source. This is not correct and can cause an audible pop when the unit is turned off. 12 volt power should be connected to a constant power source.
