I think it's about time I have to say something about your opinion of JL amps.
You drop the impedence, you increase distortion and with some amps the distortion increases dramatically with lower impedence loads. With lower voltages power output also decreases. Having an amp that puts out the same amount of power over a wider voltage and impedence range is a huge advantage in my opinion.
Gimmick you say, well I say better engineering and design.
Either you want distorted ugly muddy sound or you want audiophile quality sound. I'll take audiophile quality sound over distortion any time and believe me running my subs at 4 ohms and 500 watts with a damping factor greater than 500 I've got extremely tight bass. Not the muddy distorted crapp I hear coming from guys trying to push their amps as hard as they can by lowering the impedence.
so lets review your statement
you drop the impedance and increase distortion with SOME amps. well DUH lower voltage less power output and if you take lets say a crossfire amp which is a cheaper but VERY GOOD amp
the crossfire 1000d its not a super clean amp but its made to do one thing put out power
so it does around 1200-1300
[email protected] 12 volts now increase that up to 14 or 15 your getting MORE POWER
now the amp is only rated at 1000 watts so instead of having that 500 more watts of power you still only have 1000 with JL. The amp is nice dont get me wrong but its just a gimic so you buy their W7 subs.
so lets look at a Brax SPL COMP
the amplifier does 500 watts rms x2 @ .5 ohms yes .5 now with your theory that amp should put out assloads of distortion yet why the hell does it only have .002 THD @ rated output
just weird i tell you weird
JL amps are nice but id take something like Brax, Audison, U-Dimensions, Tube Driver etc theres many NICER amps of much higher audiophile quality sound
To obtain muddy dirty bass youd need jensen or pyramid. The AVERAGE car audio amp will do fine
I know an SQ competitor that uses tiny ass stock rf amps and he wins 1st place all the time

and guess what hes running a lower ohm load.
i have a newflash for you there are no amps that have a damping factor of 500 @ sub frequencies if you want high damping factors use them on your mids which moves 1000s of times a second

where the control is actually needed
You really should ask your manufacture @ what frequencie does the amp have that damping factor

new flash ITS NOT AT SUB FREQUENCIES!!!!!!!! find out for your self
damping factor just like impedance move all around and are depending on the frequency. do you really think your sub only stays @ 4 ohms? btw im running my single sub with around 1300 watts with an amp rated at .005 THD @ 4 ohms one 1 sub but note the damping factor is rated at 2000 yet that is rated at 1KHZ not 65 and below. Do some research before opening your mouth.
also any amp manufacture can make their amp limit what it puts out its nothing special. JL is the first to market it and try to use it as a gimic which it is
yes an amp works harder @ a lower ohm load but if you set your gains properly you shouldnt have any AUDIBLE distortion. The human ear cant hear anything below 1% and most peoples ears arent even trained to hear that %. So hows about this
