"I purchased a sub-bass speaker and amplifier for my pick-up. Everything went well, shipping, packing, price was good. I didn't understand the manufactures instructions for hooking it up. If you get this stuff hooked up wrong you can damage it. I called 12 Volt Travel, they answer their phone. Their tech answered my questions and basically walked me through the installation. I got it working then, no problem. "

"Great experience. Everything was in stock when I ordered and my whole order showed up on time and in tact."
