8 best powered

Powered subwoofers are a type of subwoofer used in car audio and home audio systems. Unlike passive subwoofers, which rely on an external amplifier to power them, powered subwoofers have a built-in amplifier.This integrated amplifier is designed to match the specific needs of the subwoofer, ensuring optimal performance.

Here are some key points about powered subwoofers and their role in car audio and electronics:

  1. Enhanced Bass Output: Powered subwoofers are known for their ability to produce deep and powerful bass sounds. They are particularly popular in car audio systems where space is limited, but users still want to enjoy high-quality bass.

  2. Built-In Amplification: As mentioned, the built-in amplifier is a defining feature of powered subwoofers. This amplifier is matched to the subwoofer's specifications, allowing for efficient power delivery and preventing the risk of damaging the subwoofer due to mismatched power levels.

  3. Easy Installation: Installing a powered subwoofer is often simpler compared to setting up a passive subwoofer with an external amplifier. This convenience makes them a popular choice for car audio enthusiasts looking to upgrade their sound systems.

  4. Size and Form Factor: Powered subwoofers come in various sizes and form factors, allowing users to choose a model that fits their space and power requirements. Some are designed to be compact and easily fit under car seats or in tight spaces.

  5. Adjustable Settings: Most powered subwoofers come with adjustable settings for parameters like gain, frequency cutoff, and phase. These settings can be tweaked to fine-tune the subwoofer's performance to match the acoustics of the car or room.

  6. Integration with Existing Systems: Powered subwoofers can be integrated into existing car audio or home audio setups, complementing the sound produced by other speakers and enhancing the overall audio experience.

  7. Frequency Response: The frequency response of a powered subwoofer typically focuses on the lower end of the audio spectrum, typically below 100 Hz. This is where they excel in producing the deep, rumbling bass that can be felt as well as heard.

  8. Wired and Wireless Options: Some powered subwoofers offer wireless connectivity options, allowing for more flexible placement and easier integration with other audio equipment.

In car audio, powered subwoofers can be a valuable addition for those who want to upgrade their vehicle's sound system without the need for extensive modifications or additional amplifiers. They provide an easy way to achieve the desired bass impact and low-frequency response in a car audio setup.

Overall, powered subwoofers are a convenient and efficient solution for enhancing bass performance in both car audio and home audio systems, making them a popular choice among audio enthusiasts and those looking to improve their audio experiences.

User questions & answers

Question: In your opinion what’s the best way to hook these up to get the best sound quality possible
Answer: The Jamo S-803 are simply passive speakers. They will need to be connected using bare speaker wire to a system that will power them. Most likely, your Samsung soundbar will not have these connections, and it will not be compatible.
Question: Is speaker wire included for connection between monitors and what is the length of the wire
Answer: The cabinets are wedge shaped (wider in the back), reversing the Atmos module would look a little strange. And this says nothing of the electrical connections. No idea if they'd actually work of not.
Question: Can you use them as desktop speakers where the back of the speakers are very close to the wall
Answer: No holes or threading on bottom for mounting to a stand. You could use some industrial Velcro to attach to a pedestal type stand or search for one similar to this side clamping one on Amazon for the S 803 bookshelf speakers.

User questions & answers

Question: Can USB 2 connections be used with this
Answer: Yes it’s backward compatible
Question: If I select one of my ext hard drives which appear in system preferences > startup disk the machine still starts with my iMac hd. What is wrong

By pressing option key on startup will show all the accessible hard drives with operating system on it , so you can choose the one you wish to boot from.

Product description

The SS8P is an all in one solution to give you great sounding bass in your vehicle without taking up a lot of space. This sub enclosure is only 2.8" thick so that it can easily fit under your seat. The amplifier is built in, so installation and wiring is clean and simple. This is a true all in one subwoofer solution with the subwoofer built into the enclosure along with a top of the line amplifier built in as well.



We focused on making installation a breeze so we designed this unit with you the customer in mind. We added high level inputs so you can install this to an aftermarket or factory system. The high level input allows you to install this even if you have no preamp outputs available.



The smart turn-on circuit will sense that an audio signal is present and turn on the amplifier. When you turn off your music signal the amplifier built into this subwoofer system will automatically turn itself off. Something else we did to make installation quick and easy is we put all the inputs and outputs on one side. This makes wiring neater and easier. Our competitor’s models are more challenging to install.



The SS8P has 400 watts of peak power and 100 watts RMS. This has great controls so you can adjust the sound to your liking. It has a level control for the volume and subsonic filter to filter out the really low frequencies which the human ear cannot hear. This also has a low pass crossover filter, phase control, input sensitivity, and bass boost.



Included is a remote bass knob, and mounting hardware but the best thing about our model is the sound. It is slim but it sounds like a full sized subwoofer If you are not happy with it we will offer you a 90-day money back guarantee. If you don’t like the sound, we will send you a pre-paid label and refund you in full!
