Ok, I'm going to go with the LG Clones for my 8 mach 5 21's but would like to max out the subs when playing music and not blow them when watching movies with 2-3hz frequencies.
My first thought was to buy two LG FP14000 ran at 8 ohms stereo (4 subs/amp) for 9400 watts with 55 cuft enclosures. This would put xmax at 2.5hz (what I really want!). I want to be able to watch movies without ever being worried about reaching xmax at full tilt.
But here is where I'm just as confused as many others when it comes to gains on amps. What if I were to buy 4 FP14000s and run them 8 ohms bridged (2 subs/amp) for a claimed 35200 watts in the same 55 cuft enclosures. This would put xmax at 30 hz. Is there any way to really turn down the gain way I could still watch movies at full tilt or would I really need to do all that with EQ like the mini? I didnt know if there was a way to measure the watts coming out at max volume of the system and make it match the lower amount of watts (9400) way all I'd have to do is mark the gain positions on each amp when switching between music and watching movies?
Thanks if anyone can help me here as I'd really like the extra 6dbs from 30hz on up for music!!!
