I got to hear my friends 10w7s yesterday off about 900 watts apiece. They were loud and clean...although everything in his ****ing car rattled so it kinda ruined the sq part. If i was him i woulda went with w7s too...but only cause he got them at dealer cost cause his brother is the installer at an audio shop. I'm pretty sure he paid maybe 50% of retail...which actually makes them a **** good deal...
