He watches it a lot more now that Noah's Arc pointed it out about a million times.

If you're going to put them in the bed of the truck, you MUST cut out a section of the back of the cab, otherwise the setup will be worthless. Just get one of those covers people use that lock down and build a box that will connect into the cab. I assume a rubber gasket/weatherstrip will be necessary with the cutout, so look into that. There must be more information on this somewhere on the net, so look around. It'd be cheaper to go for 2 15's than 4 12's. A lot cheaper. Less power and lower number of subs. You'd save a lot of money that you can put into doing the needed body work and get it done right. I have 1 15" XXX and it's loud as hell and sounds beautiful. 2 15's will be crazy. With the right setup you'll be over 150db's, which is really really loud for the average driver.

Check out the link in my profile. It lists brands that are rated in sections from Not Recommended to Highly Recommended. Brands such as Ascendant Audio, Adire, Resonant Engineering, Magnum, Incriminator, Digital Designs and a handful of others would be in your best interest. I know Ascendant, Adire and RE all have lines of 15's in an affordable price range and don't require and insane amount of power and also have higher lines at a cost. Ascendant has the Atlas and Avalanche - Adire has the Brahma and Tempest - RE has the SX and XXX. Shop around and see what you like. As far as amps go there are HiFonics, Cadence, U.S. Amps, Tru Tech and many others. HiFonics is a more budget amp that still performs really well. So check that out.

You may also want to look into a nice component set to accompany this loud setup you want to create. CDT, Adire, RE, and I think MB Quartz are all great companies too look into for this. I know Adire has the Koda 6.1 component set. Supposed to be absolutely awesome with SQ and midbass. I know I'm investing in these when the time comes.

Lastly, listen to what NG, SR20 and bumpin might suggest. Give us a budget to work with as well and the types of music you listen to.

*Note: I know that Adire and RE are both coming out with new lines in the next couple of months or so. If you're interested in those companies, I suggest waiting to see what comes about.
