These speakers are an amazing compliment to any front staging system. The free air midbass 6.5" reproduces all but the lowest of lows with no distortion. Originally hooked up to an OEM head unit, they are now connected to a complimenting JL300/4 Slash amp. The only problem I have with this set of components is the lack of a crossover component. However, the inline setup of the connection is still nothing to sniff at. For the price, these components are probably the best purchase I've made in my car stereo enhancement.
I only wish they would include a 6.75" adaptor ring though.
