Review on 🔊 Pyle PLTB8 8-Inch Carpeted Subwoofer Tube Speaker - 400 Watt High Powered Car Audio Sound Component Speaker Enclosure System for Deep Bass - 2” Aluminum Voice Coil, 4 Ohm, 30Hz-700kHz Frequency Range by Ron Kishore

I bought a full kit, got it installed at a local shop, the tech has been doing my car stereo for two decades. Today it suddenly stopped working, so I took it to the technician house. His words aren't mine "it's not blown but there is no power in the speaker, it's defective or has a bad solder joint inside". It only hits at a max power of 350, so it should run forever. To prove his point, he plugged in a blown speaker and then a new one. A good value speaker in a box with a good name.
