Product Description
MOSFET PWM (Pulse Width Modulated) Power Supply
Metal–Oxide ��Semiconductor Field-Effect Transistor is a transistor used for amplifying or switching electronic signals. We use it in computers, telephones, game consoles, cars, electrical appliances, and in this case, amplifiers. They are found in systems where information is processed or stored. A MOSFET is basically an electrical switch that allows the flow of electrical current. It allows or prevents the flow of power and creates an efficient amplifier. The � Pulse Width Modulated� is a design that is significantly simplifies power supplies. It controls the output voltage and current precisely by not only removing the output current sensing loss, but also eliminating all secondary feedback circuitry. The PWM can increase efficiency, is lighter and smaller, and can reduce total cost, as well as productivity and system reliability.

Low And High Level Inputs
There are two different ways that you can get a signal into the RS80: high and low level input. Low level input is measured in voltages and comes in the form of RCA outputs from the back of your receiver, going to the RCA inputs on your subwoofer. High level input is measure in watts, and comes in the form of one positive and one negative wire from the back of your receiver, going to the input terminal of your subwoofer in the same wire form. Low-level (RCA) input wiring is preferred for best audio performance. Always use a high-quality RCA cable for the best audio performance.
Variable Bass Boost
The difference between bass boost and variable bass boost is that with bass boost you either have extra bass or you don ��t. But with variable bass boost you have the control of exactly how much bass you want to pump out to your subwoofer(s). With the RS80 you get variable bass boost.
Phase Selector Switch
This switch basically keeps all of your speakers and subwoofers in the same phase. If you have the RS80 in the trunk or under your seat and the bass is out of phase with the main (right and left) loudspeakers, then you will likely get poor quality bass. Switch your phase selector one way or the other to discover which way gives the best bass.
Variable Subsonic Filter
Subwoofers start to bottom out trying to reproduce low-frequency signals that are below their abilities to sound off. Bottoming out is a mechanical problem and happens when the subwoofer driver reaches the limit of its excursion and creates a clacking or flapping sound, instead of the low frequency entering its voice coils. If your sub is bottoming out, short of changing the driver into one that has better low-frequency handling, you can try making adjustments to the subsonic filter to filter out frequencies below its specified low frequency limits.
Adjustable Input Sensitivity
Properly setting the gain on your RS80 is key to getting great sound out of it. The gain control is not for adjusting volume. It simply adjusts the amount of signal that is coming from your receiver and going to your amplifier. If you set it too high, you are introducing distortion into the sound. But if you set it too low, then you are choking back on what it is there to do in the first place. A technique that works on most amplifiers involves first turning the amplifier ��s gain all the way down. Then go up front and put on some music. Now crank the stereo's volume until you hear distortion. Then, back it off until the distortion goes away. Next, go to your amplifier and turn the gain up until the distortion comes back, and once again, back off until the distortion goes away.
Low Pass Filter
A low-pass filter is an electronic circuit that removes all the notes below the filter's frequency setting. A low-pass filter, set at 100 Hz for example, will block the notes above 100 Hz and allow those under that to pass. Low-pass filters are primarily used to keep high notes from subwoofers.
Boss Audio Systems RS80 800-Watt 8-Inch Low Profile Amplified Subwoofer with Remote Level Control Review
Jeep Wrangler JK owners should definitely consider this if they want to sound good yet not seem as though you have anything in the Jeep that should be stolen. IT FITS UNDER THE SEAT!! I spent months trying to find something to run that wouldn't stick out like a sore thumb when you have the top and doors off the Jeep in the Summer.Without the doors on the sound is more like a 6x9 that a subwoofer but thats why I bought two of these. It is great, if you want a really convenient way to make your stereo sound good. No one can really tell you have anything aftermarket to steal which is nice.
Look, its not going to set off car alarms as you drive by, but it also isn't going to get jacked in two minutes and sounds really nice. I usually listen to rap and classic rock and both sound great.
*************UPDATE*****************
Well not even 60 days and the Boss is down and out. It blew a fuse one day and after I replaced that the whole speaker went from bass to rattle. I cannot return to Amazon after 30 days so I will see what Boss says. Not gonna hold my breath though. $130 for 80 days is not worth it for this level of sound output. Will update if Boss does anything otherwise steer
clear!
I am dropping the original 5 star review for 2 stars which will stay there unless Boss replaces it.
