I need some advice folks. I recently purchased a Line 6 Spider V 240HC, and after getting the amp home and hooked up the 4'' speakers are blown. The seller has been very understanding and has arranged for a local certified repair shop to replace the tweater speakers in the amp for me, but I would like to contribute to the cost and upgrade the speakers so the issue never happens to me down the road. Also, I believe it would be a good opportunity for me to add some additional tone to the head unit in the process. I'm having a real hard time tracking down the exact specs and feasible options, so if anyone has some opinions or personal options I'd appreciate some "internet wisdom" on the matter.
