The Pioneer TS-TRX40 2-Way Boat Truck Speakers Pair are a set of 4-inch speakers designed for use in vehicles, particularly boats and trucks. These speakers are water-resistant, making them suitable for outdoor and marine environments. With a dual voice coil and 100W RMS power, they offer clear and powerful sound quality. Made in Mexico, these speakers by Pioneer are a reliable option for enhancing your car audio experience, especially in non-powered enclosed settings. Please note that the speakers are untested, which may affect their performance and durability. They worked last time I used them in my old pickup. UNTESTED THEREFORE SELLING AS IS. I’ve discounted due to the untested situation. Make an offer! Fast safe shipping available.
