Query: Lesson Learned

I purchased this subwoofer from Discount Jungle. After having it professionally installed, it did not work properly. My comment to Discount Jungle Customer Service was that it was defective and that I wanted a refund. She had indicated that no refunds were available after equipment had been installed and that they can only be sent in for repair. Well, how the heck are you to know if an item is defective or not prior to installation?????? So to make a long story short, I purchased another exact subwoofer from Best Buy, had it installed by the same company, and it works just fine! I went ahead and sent the defective one back to Discount Jungle for repair although I doubt it can be repaired. We have been told there is no way to repair subs gone bad:) Next time around, I will definitely buy local.
