Dude then what do you want me to say? I am simply copying and pasting what the website says. No I dont see how they would get damaged if you dont listen to them full power. Would this amp be a better fit though for either par of subs?
Simple, NEVER EVER LOOK any any amp that focuses on max power EVER again. If it has max power in the title, YOU ARE LOOKING AT THE WORST AMPS POSSIBLE. boss, crunch, power accoustik, lanzar(non opti), pyle, pyramid, autotek, performance technique, ssl etc..
anything that sounds too **** good to be true, ITS A FKING SCAM! NON of these well bring you happiness. Just **** and vinegar.
The lowest i'd go would be PPI black ice series, hifonics brutus series, belva, RE audio, MB quart onyx, audiopipe. These are the budget tier amps that are still miles better then the list I put out in the above paragraph.
You NEED A MONOBLOCK for subs pure and simple. Stop looking at 4 channel and 2 channel amps, totally the wrong class of amps to use for subwoofers.
