This replacement speaker is designed for Nintendo Game Boy Advance handheld consoles. It's perfect for gamers who want to fix a faulty speaker or upgrade their console's audio. The speaker is shaped to fit the console housing perfectly. There are no specific technical specifications like size or weight mentioned for this speaker. To install, you'll need to remove the old speaker using a soldering iron and solder sucker or desoldering braid. Cut the white connector off the old speaker to judge the wire length needed, strip the wires, tin the ends, and then install them through holes on the motherboard. It's an entry-level soldering task, but beginners are recommended to practice on junk electronics first. The glow in the dark option depends on the shell; a transparent shell is better for the glow effect. Disassembling the console voids the warranty and should be done at your own risk. Seek professional help if you're not sure. This speaker is not for Advance SP models, only for the original Game Boy Advance.
