Just don't overdrive the woofer!!! It is better to run a speaker with too big an amp instead of too small. You can EASILY blow a 500 watt woofer with a 50 watt amp when you are overdriving the amp. The MTX is a decent woofer, as long as you are not hearing the woofer pop or make other bad noises you are ok. I am very power hungry when it comes to mids and highs, I personally would actually run the 600 watt Alpine on the front mids and highs and use 280 watt amp on the sub.
