This is an excellent piece for adding bass to your car.
I searched for about 2 months, went to all the car-electronic parts shops , and even to the Honda dealer. Everytime I was shown Big subwofers, and bigger amps, It was so difficult for me to explain to those guys,that I was not the one who was trying to rattle me neighbor's windows, or even who wants lady gaga, to "ga ga"
with full throttle. I listen to all kind of music, including classical.
My only requirement was that I should have a thing which can just make all the highs and the lows sound as they should. I bought the infinity, and it really makes the Car-Radio sound 100 times better. I have a Honda Civic 2008 LX with std radio, and this thing has really made the difference. I am going for speaker upgrade next month as I have already bought them ( will power them with a P4004 4 channel amp), if I wouldn't have , I think the basslink , does exactly what the name says , links bass to your car radio. I would rate it a 10/10 for the money they are charging (as you don't need to pay for an amp, and neither an enclosure).If you are not fond of your adjacent driver knowing what you are playing, and just listen the music for it's sake, and for your own pleasure. I would highly recommend the Basslink
