Finally upgraded system..
Hey all, I'm new to the forum here and was looking to get some thoughts/opinions on what I just got installed. I have a 2011 lariat super crew that had a factory system. I just had 4 Polk db571 speakers put in and just ordered an amplified MTX thunderform sub to be installed next week. I pretty much have no knowledge about sound systems so I trusted an audio place in my city. Thoughts?
