By putting v2 on the amps they can be sold as "new equipment" and there is no reason to discount them. Still the same awesome amps. They both have RIPS for regulating power output at different ohm loads. I'm telling all of my customers to scoop up our "v1" slash series JL amps while we have them on clearance... and I'm running out of places to find them too.
That's because you're running the 300/4 (Class A/B amp) hard and it is less efficient than the 500/1 (Class D). A v1 300/4 would run just as hot or hotter.I have a 300/4 v2 and a 500/1 v1.
The 300/4 is bridged and powers a set of Boston SPZ's; the 500/1 is used to power my 10W7.
Both amps perform great however i have noticed when pushed the v2 gets considerably alot hotter than the v1.
