400W > 200W...this might be the whole picture btu take the Alpine even though the Alpine amp is probably rated at 14V not 12.5V.

yea i was thinking of that..its costing me 220$..i have that option too..but the weight limit permits me....("i can only get 50 kilos that is 2 suitcases..")

The sub weighs like 7 kilos..i guess..and i am also getting some components and some momo accessories..if i have enough room for that one..i will surely consider it..

Yup! now with a little nudge maybe you can get his to get the 1005 instead then he can drive 2 woofers if he ever needs to! :-)

no no man I only recomended 605 not 1005, Navin Also he would not be able to run two 4+4 ohms woofer with a single 1005 (1 ohms not stable). thats why I recomended 605 to him.
