Did a little shopping on the weekend and picked up a JL 12w3v2-2 for $400. Now I wanted to get the 4 ohm but JB had sold out and only had 2 ohm in stock. I wanted to get 4 ohm as I think they might be a little more reliable then the 2 ohm (power and heat issues) over time.
Now I am stuck with the decision of what amp should I run to the woofer. I want to run about 150 RMS to the woofer but should it be from a 2 ohm or 4 ohm amp? Does it make a difference?
Im wanting to get a 4 channel amp something around 4*75 RMS @ 14v run 2 channels to my front splits (that I have not got yet) and bridge the other 2 channels to make 150 RMS for the woofer.
Will I need to buy 2 ohm splits if I get a amp rated at 2 ohm or is ohm just a thing that I should not worry about too much?
Is it safe to run 4 ohm to the woofer or will i not get the preformance that i want?

Gee glad i go that off my chest....any help would be great!

Thanx

if the amp is a 4ohm per channel but capable of 2 ohms loads then u r find

when you bridge the 2 channels for the sub it will become 2 ohms

ok but u have to bridge the sub also

your splits will need to be 4ohms

hope that helps

Bridge 2 channels and run the two sub coils in series so that it has a 4ohm effective load. Then run this on the bridged amp channel so that each channel effectively sees 2ohm. This will be safe on an amp which is "2 ohm stable". If you run the coils in parallel then run it on a bridged amp channel, each channel will effectively see 1ohm which will overload all but the most powerful 4 channel amps.

Tek is spot on there. Just for a little further light reading on resistance etc murphnat, click here (http://www.fastfoursforumscarclub.com/temp/fhrxstudios/faq.asp#22). :D
