[75 Power Wagon]

I have a regular cab '75 Powerwagon and i really need some bass.. heres my setup currently..

Alpine 50-Watt X 4 XM™ Radio-Ready In-Dash CD Player

i have Boston Acoustics 6x9 3-way speakers in each door.. cant find a link to the specs on them though...

Alpine V-Power Series 360W Bridgeable 4-Channel MOSFET Amplifier

I really want some bass, in fact, i am buying a new gas tank to put under the bed instead of behind my seat.. and i was told by the person who i bought my amp that it had enough power to power two subs.. but, i've been told by raj that it doesnt.. and i have about 500-600 to put on a new amp, and a 12" sub, 15" sub.. or two 12" subs.. im not sure exactly what i should do, but here is what he suggested..

Phoenix Gold Xenon X600.1 Subwoofer Mono Amp

Phoenix Gold Xenon X12D4 Subwoofer

 

[Dracos]

Diamond Audio D6 1000.1 amp and Diamond Audio D6 12 D2

Or Diamond Audio D3 600.1 amp and the same sub

whats the difference.. just personal preference or what? the setup i was told to get above was gonna cost about 480.. but i think i can get it way down with cardomain's price garantuee

I actually went the next step up on that amp.. and i can get everything for around 420.. but now i need to get a sub box.. i have a regular cab 75' dodge 1/2 pickup.. i dont know how big i need to get the sub box or anything.. so could someone help me out! i want to get 2, but i've been told that 2 of them would not have enough air space.. and if i were to get 2, would i need an even more powerful amp?

i got the 900 dollars worth of an amp and sub down to 400.. and im probably gonna buy that once i get a gas tank.. i was wondering if anyone was willing to buy my current alpine deck, alpine amp, and boston acoustics speakers.. im thinking of replacing my whole setup with pheonix gold.
