OoooK! Can you say "Entry Level". Not offended. Understand completely what you are saying. Did all my research, homework and all of that. What I have is just a basic system to build upon myself. I didn't want to spend $1200 based off of some car audio shop guy opinion or go by "if it was me I would". I have very good knowledge on car audio. This is a beginners system that can be built upon. Pay attention to the head unit I have; Alpine 147BT (2013 model), it has Blue Tooth and a 9 Band Parametric EQ $180 bucks. Cross Over- Alpine Front Row $250 bucks. The Hifonics Amps three of them, all together around $325, I think Hifonics makes pretty good amps. Everything else I bought, well "elcheapo", for a reason tho. Didn't want to spend big dollars on drivers til I heard actual sound coming from the system, in the long run I will come out ahead. I just wanted to know if anyone out there have had the Hifonics Brutus BRZ15D4, and if yes, how do they perform.
