Burnt voice coils and damage from bottoming out are not covered under their warranty, and because these drivers stay linear right up to their limits it will not always be obvious when you are pushing too hard. An amplifier capable of more is fine so long as delivered power is held to the rating.\u003c\/p\u003e\n\u003cp\u003eOne side mounted terminal cup serves both chambers, pre-wired in 12 gauge OFC to both driver positions in parallel. Final impedance is set at the drivers: each GUS-10 is dual voice coil, so how you wire the two coils on each driver sets the load the amplifier sees. Use two of the same coil version, wire them identically, and confirm the load against your amplifier's minimum stable impedance.\u003c\/p\u003e\n\u003cp\u003eBring your own pair of GUS-10 in either coil version; the drivers are purchased directly from ResoNix Sound Solutions.
