I saw a swing kit kit on eBay with a adjustable d.k. The seller claims it comes with good instructions and photo's that anyone can do this install. For $5.50 total I purchased it. Now my question is what are the pro's and cons of these things? I have a Cobra 148GTL pushing a RM Italy KL-503 amp. If this swing kit pushes very high audio wattage into my KL-503 even with a 2 watt dk wouldn't it still cause damage?
