Class D Topology

A class-D amplifier or switching amplifier is an electronic amplifier where all power devices (usually MOSFETs) are operated as binary switches. They are either fully on or fully off. Ideally, zero time is spent transitioning between those two states. In this way, power loss is significantly reduced and making a D class amplifier anywhere from 75% to 95% efficient. To maintain high efficiency, the filter is made with purely reactive components (inductors and capacitors), which store the excess energy until it is needed instead of converting some of it into heat. Some other advantages include reduction in size and weight, reduced power waste as heat dissipation and hence smaller (or no) heat sinks, and reduction in cost due to smaller heat sink and compact circuitry.

MOSFET Power Supply

Metal–Oxide–Semiconductor Field-Effect Transistor is a transistor used for amplifying or switching electronic signals in our computers, our telephones, game consoles, cars, electrical appliances, and in this case, our 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. An electrical switch has two possible states, on or off. This is where the MOSFET performs its most important role in our D Class amplifiers by allowing or preventing the flow of power and creating an efficient amplifier.

1 Ohm Stable

The PH5000D is a one ohm stable amplifier which is able to continuously power loads of one ohm X one channel without encountering difficulties such as overheating. Almost all car amplifiers are at least four ohm stable and some are two ohm stable. One Ohm stable amplifiers are typically made to power up subwoofers that demand the heavier power load requirements to be able to perform the way they were made to perform.


Low Level Inputs With Pre-Amp Outputs

Low Level Inputs With Pre-Amp Outputs

A low level input is measured in volts. It comes in the form of RCA (low level) outputs on the back of your head unit and goes to the RCA inputs on your amplifier (Right/Left). With that in mind, you can take control of more power by connecting more amplifiers together using the RCA pre-amp outputs (Right/Left) from your primary amplifier straight to the RCA inputs of a second or satellite amplifier (Right/Left).

Variable Subsonic Filter
View larger
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 more 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 the PH5000D which has a subsonic filter to filter out frequencies below its specified low frequency limits.

Variable Crossover
View larger
Variable Crossover

Subwoofers reproduce sound based low range frequencies. This process is called the crossover effect and occurs because the vast majority of audio systems cannot cover the entire spectrum sufficiently to minimize sound distortion and maintain an appropriate frequency ratio. In the case of our PH5000D amplifier, a variable crossover is offered so that you, the listener, can have the ability to set the frequency at which the crossover occurs, thereby setting precise sound specifications on your subwoofer.

Strapping Capable

Strapping Capable

This sounds like exactly what you might be thinking. You are able to strap your PH5000D amplifier to another PH5000D amplifier and double the power that is being sent to your subwoofer(s). You now have the ability to connect more subwoofers to take advantage of the extra power.

Variable Bass Boost
View larger
Variable Bass Boost

With the PH5000D amplifier you have Variable Bass Boost, which gives you control of exactly how much bass you want to pump out to your subwoofer(s).


Power Input Terminals

When installing all Boss Audio Systems amplifiers, it is important to use the maximum gauge of wire of the power terminals will accommodate. For instance, if an amplifier has 4 gauge power and ground terminals, use high quality 4 gauge multi-strand copper wire to make your power connections. This maximizes the amplifier’s ability to draw the required power upon demand. This also helps prevent overheating that could cause failure. Always make sure, your vehicle electrical system is capable of handling the current demands from any after-market accessory.

Note: Please refer to the amplifier owner’s manual for correct wire gauge size. The power input terminals on this PH5000D amplifier can accommodate 4 gauge wire.

Fuses

Fuses protect both the amplifier and the electrical system of your vehicle from faulty conditions. If you must replace a fuse on the amplifier, always a fuse of exactly the same type and rating of the one you are replacing. A different type of fuse or rating may result in damage or cause a fire. Please refer to your owner’s manual for reference on fuse size and type. Note: This PH5000D amplifier requires 4 x 35A (140A total) fuses.

If you plan on using multiple amplifiers in your system, be certain you have the appropriate sized gauge wire to accommodate the current demands for all amplifiers and that the wire is fused correctly at the battery. Connect an empty fuse holder within 18" (45 cm) of the car battery, and run 4 gauge (or heavier) cable from this fuse to the amplifier location. A fused distribution block is recommended when using several amplifiers or accessories.

Proper Grounding

Proper grounding is essential for any electric accessory in a vehicle. Some key points to remember: Keep the ground as short as possible; connect the amplifier’s power ground terminal to the closest point on the chassis of the car. Keep this ground wire to less than 39" (100 cm) in length. Use 4 gauge (or heavier) wire. Scrape any paint away, use a star washer to “bite” into the metal, and secure it tightly using a grounding lug. Any steps that aren’t followed properly will result in a higher resistance at the ground point, causing unnecessary heat, high current draw, and potentially damaging the electrical accessories in the vehicle.

Gain/Input Sensitivity

The “Gain” or “Input Sensitivity” selectors on an amplifier are not to be mistaken for a volume setting. This setting allows users to match the gain from the source unit. To set these selectors properly, you must “defeat” any processing on your source unit. In other words, make sure Bass, Treble, and Subwoofer levels are set to “0” on your source unit before adjusting the gain or input sensitivity selector on your amplifier.

Installation

Installation by a professional increases the length of any applicable warranty on most Boss Audio Systems products. The warranty is void, however, on product that is damaged during installation by a non-professional installer.

I have had many systems over the last twenty years. Sure my hearing maybe going, but that just means I need louder and louder systems.

This is a good amp. I don't buy electronics based on brand name anymore. All electronics are made in Asia anyway. I bought this amp based on the spec's. It is pushing two, 4 ohm, 12 inchers, and a 5 ohm, 10 inch, at 1.9 ohms total. I hooked my meter up to double check the ohms.

My car lights dim at night. The sound is tight, not distorted, and prefect for rock to rap. I would snatch this amp up if I needed to build another system.

The design is clean and stealthy, I like it simple, because I don't show my systems off. I like to listen to them not look at them so this is perfect for me. The product picture doesn't give the actual amp the justice it deserves.

I recommend it. Have fun blasting out your ears, just make sure your car doesn't fall apart. I would recommend sealing up your car so it doesn't rattle, but it's your call. I am off the upset the neighborhood with my music. Later system heads.

this amp packs a punch. i got this amp hooked up to 2 slr12d (2500 watts peak) subs and it makes them hit. Not only is it powerful but it has a very basic but sharp design about it that would complement any system nicely.

Style Name: 5000-wattPackage Type: Standard Packaging Verified Purchase
I have to admit that the price of this amp had me thinking only one thing before I decided to take a gamble and purchase it anyway, to good to be true. Fortunately for me and my wallet, I was wrong. When I received this amp from Amazon my initial suspicions of "too good to be true" became evident right away. This amp requires you to remove a metal bar off each end of the amp with a supplied allen wrench in order to wire it. This is not unusual, I've had quite a few other amps in my history that have required such things. The main issue with this is that the nuts that I needed to loosen with the allen wrench seemed to be stripped. I managed to get 1 of the 4 nuts loosened with the wrench and out of frustration I took my drill to the other 3. So basically, I will not be putting the bars back on the amp.
So I wired up my amp and turned on my system and much to my surprise a giant fireball did not emanate from the amp. (I can be a bit of a pessimist from time to time). In fact I was pleasantly surprised at how much power this amp does have. By the way, this amp will not accept 0 gauge wire. I believe it will only take 4 gauge. I have this amp pushing 2 15" Kicker L5's. My subs are rated 750 RMS/1500 max EACH. It is a 4ohm DVC load wired parallel to 1ohm. And I have yet to feel the need to turn the input or the bass boost on this amp up all the way. My input is about 3/4 of the way up, and my bass boost may be slightly less turned up and it provided plenty of bass. I have all my stock speakers replaced with custom speakers (all amplified) and again, this amp does a great job with supplying the needed bass to accommodate.
So to summarize all of my gibberish, I would certainly recommend purchasing this amp.

I bought this amp a few months ago to go along with the rest of my Boss system (amps + subs). I hooked it up to 4 x 12" subs at 2 ohms and it POUNDED the heck out of my truck. I recommend buying it to all my friends.

Can't beat the performance this amp offers for the price. I have this amp pushing 2 15" Sony Xplods (no not the crappy walmart ones) and it draws so much power my headlights dimmed at night. Added a 2 Farad BOSS capacitor and to fix that and this thing makes my subs KICK! I have my subs running at 2 ohms right now and they bang HARD. Amp can take it without a sweat even when playing for a long time in bass intensive songs. Would suggest getting the PH4000D or PH5000D if you have the extra money though. You get a little distortion when pushing RMS and it can get kinda bad when turning it up but as long as you take that into account when choosing your amp you should have no problem.

I bought this thing to replace my old 5500d from kole which was my best amp and this thing I could tell was weaker the first month but still gave me decent pump then the sound started going in and out so I checked it out n saw it was going into protect mode on and off wasn't hot or anything .took it to a audio place and they informed me that the amp was not 1 ohm stable like boss claims so it was going into protect mode they wired it for 8ohms and no more cut offs but my bass suffered HEAVILY.i found my kole 5500d on eBay and installed it now I'm back to my old self. I contacted boss and got no email back so screw em.this thing worked fine then failed in 6 months.
