I currently have an Stryke AV-12 in an 18" sealed cube with a PE 250 watt amp. The 500/1000w amps that PE has on sale now are very attractive. I was thinking about the 500w which would be perfect for my sub but for an extra $100 I could get the 1000w and be ready for a driver upgrade at a later date. Would the 1000w be too much for my current setup? The DIY bug has bit me hard so I know I'll be doing another sub project someday.
