Hey there if you are looking at this then you already know the JL audio name I was going to place a system in my car but other things had come up and I don't see that happing I would love to get what I paid LOL but I know that will never happen so I would like to get 450 and that is a great price here are just some power rating

Front Channels:
100 W RMS x 2 @ 1.5 ohm-4 ohm
Rear Channels:
25 W RMS x 2 @ 1.5 ohm-4 ohm
Subwoofer Channel:
250 W RMS @ 1.5 ohm-4 ohm

Maybe if you have a new Navigation we can work out a trade of Equal value
