Summary: Great speaker, sounds loud and clear mounted on the roof rack of my 2005 Jeep Liberty. For buying one used, i was unsure but it came with the manual and original box and everything. I could hardly tell that it was used. I did have to splice the PA speaker wire to aux cable but that was no big deal.
Summary: Speaker is a but weak. That said, it's a sturdy metal cone and easy to install. I hooked it up to the PA feature for my CB. While not overly loud, it's loud enough to hear from about 25 ft. It doesn't come with any length of audio cord so that is extra. No big deal.
Summary: I purchased two of these speakers to build a DIY electronic game caller similar to the commercially-available FoxPro units. I am very happy with the result. PROS: - The output is VERY loud, if you supply the correct wattage from an amplifier.
