MRV-F340 vs MRV-F540

[QBA]

Hi

I just bough a Alpine MRV-F340 thanks to some tips from people on this forum and in particular 1st MP3 in NH

Now I have the oportunity to pay a little bit more and get another amp, taking this one back to the store, but I need to ask you guys if you think is worth it

So here are the two apms specs, is there a big diferent bettween the two and wich one is the best in your opinion ?

The F540 has more power, more adjustable crossovers and a better signal to noise ratio.

If you need the extra power or if you need an amplifier that can bandpass a signal with its crossovers then its worth it.

What bandpass a signal with it crossover means?

Use both the high pass and low pass crossovers at the same time.
This is needed when actively powering the mids or midbass drivers.
