I bought two PC of these monster subs and a piece of T2000-1bd rf amp... it's so powerful and the spl is really amazing. I installed it to my old look Toyota revo and it is the most powerful car audio set up in town. It hits 147.2db on termlab without any sound proofing or body modifications on my vehicle. I can recommend this product because of it's durability and quality. What you see is what you get!!!
