I recently bought this truck and wanted to upgrade the sound. Went to a shop and told them generally what I was looking for (cleaner and slightly louder sound) they set me up with this. As far as the kickers go they sounded different in the store. They're not as loud as I thought they'd be and they lack bass. Will adding another amp improve this? The sub has way more bass than I was looking for I like the knob best at a quarter turn. The issue is it gives me a headache, from the back of my neck up. Is there anything I could do with the settings to prevent this? Not too sure what to do here looking for recommendations.
