Excellent. My second QBomb box. Put 2 Skar EVL 8 subs in and it bumps.

  • Punchy musical upper sub bass 40hz+ isnt boomy lows box; be prepared to modify, glue/seal terminals.
This box so far from the time I've been working on it, requires quite a bit of work to be a standout box. At stock air will leak out of the terminals, and they will need to be sealed with caulk or foam. I also found that glue was minimal on the inside so I went, and added more to all of the corners and edges on the inside, so that it will last. I also went ahead and stapled some poly-fill batting to the walls to help with the sound. With all of these modification's its about an extra 25 bucks, but if you have the time, and prefer a bassy punch, this box will deliver musical sub bass very well. The subs I used were 2 8 inch ssls for not being focused on 40hz or lower because of them being rated at 50hz anything lower than 40 from an audiophile perspective is uneeded. Before all of this I had a 12 inch sealed infinity primus sub and that was way to boomy and annoying to eq properly, even with all of the low passes and crossovers. This box, with just 300 watts fills my 03 Camry le with very fast, musical, punchy sub bass, that can shake the car and doesn't overpower other frequencies or the mids. Overall it is tuned well for musical punchy sub bass, and doesn't have any boom or bloat to it, only get this box if you're willing to put a few hours of work into it, to bring out its potential. ... show more
