That's is very good to know . And I have some other options now. Leaning towards audio legion or soundqubed or what ever is best priced out of the options u listedZenon is the korean buildhouse. Zenon and S&i are the 2 main players. Most amps will be comparable +/- tolerances. Some companies upgrade the amps. Audiolegion for example beefed up the caps on their boards. Sundown scv focused on optimizing power for 12v systems.
Synergy and Twisted sounds are 2 more to look at. The synergy 15.1 is 399 and its a 2k. The twisted 1.8 also
Id do the synergy or twisted. Both do 2.2-2.4k certified for 399
Looking two runs two sundown sa12 or something very similar. Have batt xs3400d need alt got big three plus need sounddeadner. Money has been tight. But that's all I need lol.I live in canada shipping doller difference makes things very costlyDo you need every bit of power? Cuz the al is the strongest, and might be a few tenths louder on a termlab.
But it wont be audible probably. Is your electrical done? If it was me, id rather save 100$ by getting the twisted or synergy, and put that 100 towards a battery or wiring.
But every amp in this thread is good. They are all the "right" choice.
