This crossover is just too cool! Its really easy to use. As for the sound improvement? Yes. I was running a four channel amp and the sound was good.. The crossover enhanced the sound in my ride. This cross over has given depth to my systems sound. The highs are more clear. The midrange is more distinct. I listen to hard rock.. So the example is the lead singers vocals appear to be higher than the guitar. In other words this cross over has given my system a 3D effect.. lol. The sounds are more balanced. The unit is small and will easy in most spaces. Also.. The unit can be powered by 16 gauge wire.. I used 10 gauge. The power ports are small and you need to plan on using a smaller gauge wire. like 10.. 8 gauge will probably be to big. So the power requirements are not as demanding as other components. This cross over can take 1-2-3 channels from your head unit and convert them to high, mid and bass channels! So no matter what type head you have, this units can take those signals and prep them up to send to your amp. IT ALSO COMES WITH A REMOTE FOR YOUR SUB-WOOFER. So in closing you get a small component, small power requirements, good price, very versatile and great sound enhancement. Its worth buying. I highly recommend this product. I hope your experience is as great as mine.
