I bought these to replace the stock blown speakers in my van. I am running them off a JVC KD-R200 deck, and they sound good. I know this size speaker is not for bass, but having the bass gain on my deck at 3 (out of 6) they distort. Turning down to 1-2 seems good until I turn the volume to high (40+ on the dial). More power would help (deck pushing 20 rms/50 peak per channel and I seriously doubt they will handle 230 rms & 450 peak per pair). The highs and mids are quite good as well, and actually over run the factory 6 x9's in the rear. Overall, for a low dollar replacement, they are good speakers. I will eventually upgrade them as funds increase, but I am happy for the time being. If you are looking for something to replace blown factory speakers, this is a good choice for the money.
