First, let me say what my goal for the system was in the first place. I wanted a well rounded, high volume and high clarity system. I have a 2005 Subaru Legacy GT sedan. The wife imposed a few rules that I had to adhere to as well. The trunk still had to be fully fuctional and a baby stroller would have to be able to fit. So, in the rear passenger side tuck in behind the wheel well went my enclosure. It's made of fiberglass and MDF and is formed into that area. It's approx. .75 cu feet sealed. It is being run off of the sub channel of a JL 500/5 which is 250 watts.
Now, onto my review. It has fufilled my goals completely. With a variety of music it does extremely well. Primarily I listen to rap/ hip-hop, dj music and some rock. As with any sub system I reccomend some type of external level control for fine tuning,(i.e. head unit sub-level control or bass knob connected thru the amp). At low volumes the bass is pleasant with very rich fullness. I liken it to a pair of good 10's or a single 12. With the volume cranked this thing will rattle your brain. No matter how hard I push it this sub keeps asking for more. I know full well this could easily handle 500 watts, however that would be more output than I had aimed for. For alot of you, this may not be sub for you. Reason being is that alot of people are looking for an insane amount of output and though I feel it is fully capable, Price is the biggest hurdle. For accuracy, clarity and depth I personally feel this sub cannot be beat. I got this sub for a little over $250 shipped and while that is pricey for a single 8, You will not be disapointed. The people that have heard this system are in disbelief that A) it's a single 8 and B) that it's only running on 250 watts. I may post a few pictures so you can see the final result.
In conclusion, if your budget will allow and you have similar goals in mind, spend the extra bucks and get this subwoofer. I have yet to find a single negative side to this decision for the system I wanted in this car.
