More power?

Unlike in Star Trek more power will not get you what you want. Why? Well for instance you could push 10,000 watts into an 4 ohm woofer, but it would fry in under a second, even less for 2 ohms. You see you want voltage, not current. The voice coil of the speaker is what makes the cone move up and down. Almost all subs use 20 gauge or smaller wire. Now how much current can 20 gauge sustain for an indefinite period of time? About 10 amps. How much voltage? About 200 volts. See where I'm going? Why did I use an 8 ohm sub in my car? Well my 8 ohm sub will soak up 60 volts at 7.5 amps. That's 450 watts RMS, 900 peak with an oscilloscope. Most subs can't play at 60 volts before breaking. However my can because of the high resistance. Because my sub puts out 107 db at one watt it requires very little power to operate. So at 450 watts I can put out 134 db. If you take that POS kicker which 88db efficient and put 450 watts into it you will get 115 db. Big fat freakin' difference eh? And there is also a limit to every subs maximum output potential, you will have a hard time finding it unless a. Your sub is a pro audio driver, in which case it's in the spec sheet. Or b. You will have to contact your speaker mfg to find out what it is. Most of the time the mfg will not want to state it because it is a rather low number. Now I know what I just said above probably rattled your brain and you have some questions, like "but my friend down the street has a kicker solo l17 and it sound loud." Yes it may sound loud but a bet you a 1000 bucks he can't play it that loud for very long, I've tested my sub at 50 hz at 60 volts for 48 hours, my sub never broke, and my amp stayed room temp (ap1200). His will most likely overheat in a few hours. Also when looking for a good amp go with a high RMS rating at 4 ohms, believe it or not, stay away from mono sub amps. They are meant to run at 2 ohm's which is cheating by allowing more current rather than voltage, current is easy, just make the wire on the transformer core larger, voltage is more difficult you need to wind more wire, 60 volts output (at 12 in) is a 1 to 5 turns ratio. Now typically high voltage does not mix with high current (low resistance) which is fine, I like my 8 ohm sub which actually halves the THD.
