Description

- From the Manufacturer Advanced Protection Circuitry view larger Power Series Amplifiers view larger System Application Diagram view larger The Strong and not so Silent Type Custom Terminal Block for Speaker Connections view largerPower AmplifiersThe Pyle Power Series Amplifiers will provide your audio setup with a powerful new sound. Add performance and quality enhancement to your music when you upgrade your audio system with these rugged and high-efficiency amps. Enjoy tomorrow’s advanced sound technology that outperforms all other amps in its class. This lineup of Pyle Power amps raises the bar when it comes to true sound quality. Get that sound you’ve been looking for with crisp music reproduction for any mobile audio environment. Sound SpecializationThese high-efficiency amplifiers host impressive power output wattage and are where form and function meet. Enjoy sound and performance enhancing features like Ohm specific stability, Mosfet power supply, PWM (Pulse-Width-Modulation) System, Glass Epoxy PCB, silver RCA inputs, custom terminal blocks for speaker connections, strong frequency response, and input impedance rates along with plenty more features that make the Pyle Power Series Amplifiers stronger than the competition. Intelligent Design Safety features include power and protection LED indicator; soft turn- on/off, thermal, overload and speaker-short protection. LED Indicator shows when the amplifier is powered up normally and when your system is experiencing a protection fault. Pump it UpTake advantage of the Bass EQ Boost and turn it up. Make adjustments to the Bass EQ settings until you achieve that extra amount of kick you’ve been waiting for.Strong Sound – Powerful StyleThe jet- black design leaves a clean finish on the fortified aluminum heat-sink. The stream-lined and high-tech appearance will definitely add some muscle to your audio. Total Audio ControlOnce you’re connected, customize and adjust your listening experience to your liking with the amplifier’s control center. You can personalize and fine-tune settings like:Level (Gain) Control – These are basically volume controls. This will allow you to adjust the incoming signal to the amplifier so that it works well with your headunit or to match the level of other amplifiers in your system. Phase - Allows you to change the relative time that the waveform meets your ear. With standard subwoofer installations where the subwoofer is behind you, the phase should generally be at O. When subwoofers or woofers are in the kick panels or door panels, an adjustment is useful in delaying the timing of the wave meeting your ear.High- Pass Filter – The High Pass crossover is used for sending midrange and high frequency information to a particular speaker. Activate the High Pass crossover if you intend to drive satellite or coaxial speakers in the system along with subwoofers driven by the amplifier’s channels. Even if your system does not include subwoofers, it may be helpful to activate the High Pass with smaller speakers to protect them from low frequency information to achieve better sound.Low-Pass Filter - Filters high frequencies out of the music and improves efficiency and sound quality by allowing only the low frequencies to pass to the subwoofer. Sends only low frequency information to particular speakers. Low Pass crossover activation is usually desired if you intend to power subwoofers. Bass EQ - Variable from a range of decibel adjustments, this feature regulates the impact of your bass kick. You’ll have manual control over balancing and correcting the frequency range of a given sound. Crossover Switch – Basically acts as a filter and limits selected frequencies going to a subwoofer, which gradually reduce frequency signal strength. Routes output of the Low Pass or the output of the High Pass filters, or ‘Full’ to the power amplifier.Please refer to table below for amplifier specific information and adjustment options.Speaker Output ConnectionsConnect right and left speaker wire to corresponding speaker output terminals. Be sure to correctly connect the selected speaker wires to their respected speaker terminal, this includes both positive and negative wiring. Improper installation/wiring will result in the speaker cones to move out of phase which can cause bass cancellation. Input ConnectionsThese amplifiers have inputs for Low Level input connections. The Low Level signal is carried through RCA connection cables.

  • It's decent.
So far so good. I had to jump my subwoofer to get up to 4 ohms but the amount of power i got was worth the hassle. The only problem i have is there was no remote but luckily it's universal with other amps and i already had one.

  • GREAT and very very cheap!
The RMS power it shows on the box is kinda debatable, it says @ 4ohm you should get 240 X 2 which is very low for a 4000w amp but! it says that if you bridge you will get @ 4 ohms 4,000w rms. so i dont see how it could jump that much and i'm not sure of the real rating of this rms but i have 3 12" xplods hooked up and wow i'm scared it will blow them! at first i was depressed cause it was very loud then i tuned the gain on it and the level then it really wanted to kick! lol its very loud but make sure to have the volume down then work your way up while tuning the amp. but seriously you can't get a better amp and this big for the price! you cant push 3 12" 1200w 500rms subs that hard and only half up for $90.00. i really hope this helps and by the way, make sure you have a good setup and big power cable or you will find yourself getting a very hot amp. ... show more

  • jsut what i expected (EDIT) NOT WORKING
Boughten June 2nd SEPTEMBER 13th this amp was great and perfect for what i wanted and the price. it is much cheaper than name brand. i can tell you that it isn't up to par with most name brand amps and a lot of these are hit or miss but i got a hit. so im pretty happy with it and no problems hooking it up either. October 21st UPDATE!!! am isn't working anymore. im not getting any output through to my sub woofers. I am very fluent in electronics and measured any voltage or amperage and there is nothing going to the sub woofers. I have plenty coming in and there are no fuses blown. all cables and wires have been checked and it is grounded properly. Protect light is not on and power light is on. VERY VERY UPSET CUSTOMER. I did make an uh-oh by throwing away receipt and warranty papers because it is only 4 months old i dont know what would be covered.. thanks ... show more

  • On Point
In the beggining it cut of about 2-3 times running 2 12' competition subs. It seems it just had to be broken in. About 2 months in I haven't had that problem anymore 👍🏾
