I highly doubt that these subs would "break windows". It would probably be possible to maybe crack a few windows, but even at that, you would need a pretty big box and it would have to be tuned just right. Do you now if they are dual 2ohm or 4ohm subs? I would recomend the sound storm 4000.1. Yea, it may sound cheap, but it can put out a true 2300RMS at @ 2ohm and it is 1ohm stable. I have been very pleased with this amp and it has never let me down.
