two different setups

Hello folks.

Again im coming here for opinions of people who have used different subwoofers. Thanks for all the help in advance :)

There are two setups that I need help in.

First I got only 150 watt rms *:(* and need to setup a nice sounding subwoofer. Ive narrowed the choice down to a JL W1v2 12" and a Kicker Comp 12" ... both in ported boxes. Which one would be 'louder' ? Would any other subwoofer be a better option with so little wattage available.

Next up ... I have this friend who asks for something that should be kinda loud but SQ is a must here. Around 4-5 cuft of space available. A 2 channel bridgeable amplifier giving 1060watt RMS @ 2ohms and 660watt RMS @4ohms mono (bridged)

What would be a good combination ? Would 3 Alpine Type-S 10"s be good in compact sealed box ? Or any other subwoofers ? Or would the result be better with 2 15"s ?

Any old links or some comparisions would be lovely!

Thankyou all :)

Ahhh yess ... I think I should have mentioned the fact that a JL W7 is sooo out of the budget :(

Having very different prices here ... im estimating a can get two CV Vmax 15"s ... 3 Type-S Alpine 10"s ... and there was this used CV Stroker lying around at the shop too. Should I fancy the stroker or go with dual Vmax 15"s ?

I just read the 'Single VC on DVC sub ' thread... would this be helpful in regards to the first query ??? As in I can rig up a better subwoofer to the same amplifier ? A 12" CVR or a W3 ? Or any other you would recommend ? We dont get much brands here ... Polk Audio, RF, JBL, JL Audio, Fusion, Kicker, Kole Audio, Alpine ... id be inclined towards SQ ... as a ported box would give enough "loudness" for me.
