Punch Up The Volume with Speaker Protection Circuit Boards
Keep your speaker blasting your favorite tunes with speaker protection boards that help prevent various nuisances and hardware failures. A large assortment of these devices is available on eBay, and the following questions and answers may help you better understand your options and select the one you need.
What do speaker protection boards do?Speaker protection circuits carry out numerous safety-oriented functions. These devices are to be applied directly to audio power amplifiers, one of which is installed in the majority of speaker systems. Once attached, the circuit boards prevent amplification-stage failures, voltage overloads, loudspeaker terminal, and other common issues.
In the long term, the purpose of these boards is to increase device lifespan. They will also enhance performance by removing or offsetting issues that can interfere with overall audio quality. Short-circuits bring with them grainy and static-filled sound signatures, for example. With these circuit boards, your speaker will sound like new with every song on your rotation.
Can these parts be used as replacement hardware?Absolutely. They were originally designed to function as replacement devices. However, there is nothing keeping you from using these for a killer custom sound system. So long as the target device or home project is using a compatible amplifier, the device will work as well as it would with the original hardware.
Which speakers are these parts compatible with?These device's compatibility isn't limited by your speaker's manufacturer but rather by the amplifier the manufacturer chose to use. As such, each respective speaker protection board listed will be compatible with a different style of amplifier. In some cases, more powerful amplifiers require more circuit boards to be used in order to provide adequate protection. BTL amplifiers, for example, require two circuit protection boards in order to prevent power surges and hardware failures. Below are some of the more commonly supported amplifiers available in these listings:
- Class A Amplifiers
- High-Power Class AB Amplifiers
- BTL Amplifiers (requires 2+ protection boards)
They are. Many of the listings offer bundles that include the board, installation hardware, and some general instruction. Boards are available as individual products as well. Listings will mention whether or not they are a used board, refurbished, DIY-single, or DIY kit in their description. DIY hardware is new hardware manufactured to act as a replacement for original devices. Used products are circuit boards lifted directly from old speakers, and refurbished options are used boars with some third-party cleaning and testing thrown in. There is an effective solution for everyone with eBay's remarkable assortment of listings.
