Need some pointers/help/recommendations

[DaNxtLT]

Hey everyone. I'm new to the car audio world and I need some help with choosing subs/amps/etc.,

The reason I haven't even started buying anything yet is this: I drive a 1996 extended cab silverado which means no trunk, and I need my back seats... lol. I was considering getting this custom box in order to keep them under the seat, so I was wondering if anyone has one of these or has at least seen one installed.

I was think about getting something along these lines as far as subs go:

And these are on sale at Best Buy, but I'm assuming they're on sale for a reason lol

I'm not wanting anything competition level or insanely loud simply because I can't afford it lol, but I would like some bang for my buck ya know?

Sorry for the long post guys, this is my first time buying these things, I just don't wanna waste my money on useless shit.

Thanks in advance for any help guys

What is your price range?

what amp do you plan on powering them with?

oh and the hifi sound boxs are pretty much cardboard and will probably break in shipping i know first hand!!

I'm not 100% sure yet, I'm thinking $400 max if possible. I was looking at this amp, but I'm not sure what to look for:

You think one of these are better? And yes, I also like that one better, but I'm pretty sure the only way to achieve that is build it yourself

[bdog]

why not build it your self its alot easyer than you may think

[DaNxtLT]

I thought about it, but I know there are a lot of different dimensions and speciific stuff that I don't know how to calculate. Plus I don't know the best stuff to build it with. But I'm sure I could find out.

its all easy and fun to measure the space treat it as three separate boxs

[Maebros]

there are a ton of people on here who can help you out wiht a box. as far as all the calculations you can make that real easy. just find the measurments of the space you wanna put your subs in and then pop the measurements into torres.
