Have no knowledge of the installation of such devices, has but then worked quite well using.
Installed, connected and turned on, and what can you say? More than I would have wanted in my dreams!
Of course, this is not a Double 30cm Subwoofer with 1000Watt but for the size and the price, it is probably the best thing you can get!
I use it more as bass support and he carries out his work perfectly and although I have set him only half power.
And if you take turns on a Bass song Let term the car vibrate so strongly that you can not see much in the rearview mirror.
This subwoofer is more than worth its money and I recommend to everybody looking is this subwoofer!
