With subwoofers its the box that determines its results, poorly braced box with expensive subwoofers will yield poor performance and some may write up a review to state not to buy the product without indicating the box they use, prefab or custom made, power supplied and the vehicle it is installed. Regardless of the budget and the brand you will use, the box will either make or break it in your sound performance. Remember, even if you make the box up to the manufacturers specs, you will have different outcome in each vehicle. One factor is the cabin loading of the vehicle which again differs due to box placement. If I had the choice of either, I would incline towards Rockord Fosgate, as they have been churning out reliable gear over the past 4 decades and if you stick to the box requirements and don't over-power them x 2, your system should outlast your car provided you don't drive your gear to distortion , theoretically speaking!
Happy Thanksgiving Guys
