The explanation of a "WackPack" according to RadioActive Radios:
What is a "WackPack"?
A WackPack is a process exclusive to RadioActive Radios! About 12 years ago, we saw a need for customers who demanded more audio, cleaner signals, and wanted to be bodacious! After years of research we designed a way to make your radio do just that. We redesign the audio/wattage section of your radio (and other stuff too!) to make your radio do max watts, max audio, and swing. But operate at much cooler temps, helping your finals last A LOT longer!! Its like watching TV, and you hear a TV commercial tons louder than the show you were watching. They do that by audio, that's what we do to our radios! You'll love a WackPacked radio! Tuned/Peaked, Peaked/Tweaked, MegaTune or what ever you call the garbage stuff CB shops do are so basic it makes us laugh. If your paying for a tune/peak honestly you're getting ripped off. What they do is hack out your audio limiter, turn a core, or spread a coil. All together making your radio get a little more audio, but its like a fat man running up a hill! Won't last long, or strong! And please never be fooled by modulator kits! What a joke, yes some semi work, but you're paying $30-$60 for a resistor in a box! Will you WackPack my radio that I already own?? Yes, as long as it qualifies to get one done. Most Big Radio Chassis do, but please don't ask us to WackPack your Cobra, Midland, or Uniden, we specialize in Big Radios!
