I took the boat to Frank at CarToyz this morning at 7:30 so he could diagnose my system situation. Again he took the time (probably 35 min.) to adjust the amp and improved it quite a bit. In todays world, service is lacking to say the least and Frank even took his tennis shoes off before boarding (It got pretty cold on the tootsies, sun just comes up here at that time) Anyway I really appreciate the time and effort and the results plus an HONEST OPINION. If I do upgrade in the future it will be done by CarToyz, Thanks a bunch Frank NSF
