I must say I am very impressed with these little 8. I have them in a sealed box about .5^3 each powered, now get this from a z1000d. I have each running off of a seperate channel at 2 ohms which would give a claimed max of 750, and rms of around 375 and they are takin git with a smile. not a bit of distortion. extremely tight and very precise. they have completley amazed me. they will play any type of music that you throw at it. Rock rap, techno,. I would definitly suggest these to anyone on budget. I build a box where my middle seat of my dakota was at it is perfect. almost two loud with two for my taste.
