I have had quite a few. They are little monsters for how small they are and I was happy with them. The downsides are they are more suited for active crossovers. The onboard crossovers are very limited on the amps themselves. They only have two pots which is for gain on channel 1/2 and 3/4 and alot of people don't understand the shared negative/positive terminal they use.
I'll say the same thing I always do about taramps crossovers. Don't use them unless you absolutely have too. Preferably run some kind of processing or whatnot so you can just avoid having to set the crossovers on the amp.
The amps are otherwise great in my experience, plenty of power and small footprint.
