if he buys your two 12W0's then he can use his 250 watt amp, then get another amp later and another two 12W0's. way more cone area than two 10W3's.buy my 2 12W0's
Honestly I would get 1 10W3 since you plan to upgrade the amp in the future then you can also get a second sub.
Or get 2 12W3's and run them off the amp you have and get a better amp later.
Some people use there cars to hold things other than subwoofers. Yea he "could" get 4 12's if he does not mind having NO space. He could also get 2 12W3 V2's and buy 2 more later and a new amp for a total of 4 and have better SQ.if he buys your two 12W0's then he can use his 250 watt amp, then get another amp later and another two 12W0's. way more cone area than two 10W3's.
why would he be looking at a sub that can handle 250 watts if his amp is capable of delivering 500 watts?Also you can get 2 ohm 12W3's which shoudl double the wattage output of the amp so you could run maybe 250 watts to each sub...Unless your amp is 250 watts max bridged.
i would go with one 12w3v2
