These component car speakers features 6-1/2" polypropylene woofer cones with a rubber surround and 1" soft dome tweeters for brilliant audio. Image Enhancer IV technology helps prevent reflected interference while reducing distortion for clear sound.
I'm using a 75 W amp to power these. They produce powerful bass and have a pretty good frequency response. The in-line crossover does not occupy a lot of space so it's great for compact locations. Tweeters could have been a little more powerful but they are okay for their size.
Pump up the volume in your vehicle with this Power Acoustik Razor Series RZ4-1200D amplifier, which features a MOSFET power supply for efficient performance and 1200W maximum power for reinforced audio. The compact chassis allows flexible placement.
Don't underestimate this amp. It is pretty powerful. I have bridged two channels to power my 300 W sub and using the other two channels for the front speakers. It pushes the sub to it's limit and nicely amplifies the speakers. It does heat up a little. While you can select LP or HP, it does not have a frequency range dial.
