CURRANT DRAW ???
Is this a FACT or just a GUESS ??? ............ I have run these speakers for over 3 years now, some of which was @ 80% volume .... They still work great ..... JBL has been selling 2 ohm speakers for DECADES .... I haven't heard of Stereo failures due to this, but I'm open to Genuine info .......... Mike

That was in the days of tubes and transistors. People who hooked up 4 ohm speakers to 8 ohm amps sometimes had a problem with overheating and / or burnt output transistors because they couldn't handle the higher current. I honestly haven't heard of any problems in modern systems with impedance mismatches, perhaps because they have better circuitry to accommodate a varying current nowadays.
So, most likely it's not a problem for the system to handle different impedance speakers, but if someone does experience a problem that would be a likely cause.
Unfortunately BRP doesn't publish specs on their head units (at least I haven't been able to find any), so I can't tell for sure. My electronics knowledge comes from 10 years as a Navy electronics tech and 20 years playing around with computers, so I'm probably not the best source for info on current tech.
Great explanation. When I was into stereos, matching speaker impedance with the stereo was a function of sound quality more that potential damage to equipment.
