You kind of lost me here, but i really do appreciate your time helping me.

Which one do i want, the first or second one. First one is the 4ohm sub, and the 2nd one is the 2ohm, and i beleive the 2ohm is the one you told me to get, correct??

Thanks a lot!

a 4 ohm driver is what you use to mount the speaker to the box.... :happy055:

Im kind of lost here because somebody else told me this about it, (Same question i asked here)

Get the Dual 2ohm if you are sticking with the Power Acoustik.

You will be comparing 560rms(if that is its rms power) and 600rms, which will sound just about the same. You need to double the watts to get a 3db gain, or a good noticable difference. The only difference would be is the quality of the amps. Power Acoustik isnt trash, but isnt not what a JBL is, but they are pretty good for what you pay for them. JBL on the other hand are pretty well built amps and it will for sure last you.
After reading what you said the first time i looked some stuff up. My power acoustik amp pushes very hard. The car audio store that installed it told me they have previously installed a few of these and they pound a lot harder than it is said to, and i beleive that. It draws a lot of current with 4X25 fuses, so i had to put a 100amp circuit breaker up front and have been fine.

I looked up some reviews on that jbl amp quick online, and i read a lot about how bad the amp was, always shutting down, overheating quickly etc.

So therefore, im going to stick with the power acoustik amp, i love it now, so im sure it will be fine. http://www.sonicelectronix.com/item_6198.html Thats the specs, can you just double check it, and make sure of what sub i should get. The 2ohm or 4ohm. That would be greatly appreciated.

Thanks a lot!

If you upgrade the amp, you are going to need a dual 4ohm sub to get the most out of the amp. My suggestion would be to decide on which amp you are actually going to run and get the sub to match the amp.
Out of curiousity, what made you decide to go with the L5 over the cvr's??

I picked the L5 over the CVR's because i listened to both at circuit city and liked the L5 a little bit more. And also, it was a lot cheaper, and if i got the CVR's they were refurbished (sp) where as the l5 is new.

Alright i saw that your right, bridged its min impediance is 4ohms. This amp puts out 560RMS bridged and really pounds hard. Do you think i should go with the JBL, or stay with this one? Will i notice a huge difference?
