[QUOTE="Jakerrr, post: 8446427, member: 637923"] For the 750, a 1500 watt amp would be perfect, just set the gain so there is no clipping. I don't have any experience with the 1800 but if you have stock electrical you might as well go with the 750 since you won't be able to use more than 1500 watts or so anyway. If you are upgrading electrical get a soundqubed hdc4 15, or a zv3 15 if you won't be able to fit the hdc4, or if you can fit 4 ft^3 plus port (to figure this out, get some box builder that will be building the box for you to model for it and give him your available dimensions) then get a zv3 18. And a 3-5 kW amp. That is if you want something that will just be extreme overkill, for fun Rated power with the good brands is under rated and likely represents clamped power (power after impedance rise). An amp that does 1500 watts will only really be giving the sub like 2/3 of that at the very most. Sometimes, especially around the resonant frequency, not even 1/4. At max volume. The sundown sa-15 is rated for 600 watts and we've found they actually max out on xmax at around 1400 watts CLAMPED power. So you can use an amp that does many times the rated power and usually be fine if it's clean power [/QUOTE]
