Why even go with those woofers they are not good at all imo my friend had to keep shippin his back. You can get an American bass xfl 10 for 131 shipped a way better choice for only a couple more dollars than that
I'm going to guess your choices are pretty limited being in Israel? It might be easier for us if you list some of the options that are available to you.
I think that amp is fine for your needs. I had one running 2 8L7's then my 2 Sundown Sd 10's till I traded a buddy for his BRZ-1700. I could not notice much difference in te guts between the 2 amps. I think the BRZ has a better heatsink design and a CEA rating thats all I could see.
