I believe this to be a matter of opinion. It all depends on amount and clenliness of power being delivered, and a truck load of maths to make sure your enclosure is the right size, has the right ports, construction method and wadding. Then theres type of car and amount of sound deadening, and of course, what your looking for. Alphasonik aren't what they used to be, because they dropped prices to enter the mass market. They're original goal was to make quality product that was loud, but didn't sacrifice on sound quality. Kicker (having gone mainstream years ago) care mainly about making a product that doesn't break down and cause costly warranty claims. They make a good quality product that sounds good, but the higher end gear is designed for SPL competition and thus loses quality.
My personal opinion is MTX make the best woofers. They we're a boutique brand for a long time before they went mainstream and instead of sacrificing quality to bring down price they found ways of making things more efficiantly. They also make THE biggest and most powerful woofer. The Jackhammer. It's a 21" 150pound monster that needs several amps to drive it.
You need to match the speaker with the amplifier. Better or worse is not the question. The question is dynamic range and the possibility of overloading the amplifier. If the amplifier is rated 4 ohms, use a 4 ohm speaker. Same for 8 ohms. Do not "mix and match".

Depends on how much juice the sub uses ,but almost always the answer is yes especially if you want a sub that kicks at all.You'll need an amp if your subwoofer costs anywhere over about 50 USD. Otherwise the subwoofer is probably junk and you shouldn't waste your money on it anyway.

Kicker is a much better quality subwoofer than Pyle, and it will have much better bass as well.

The Kicker 1500 Watt subwoofer is very, loud, but doesn't have the best clarity and can get muddy. Consider Pioneer subs.

The Kicker enclosed 12 in. subwoofer can always be connected to your factory radio, and it should be very easy to do.
It's a dead subwoofer.
Kicker solo is a great all around subwoofer for the price. Good deep bass low price who could beat that?
The Kicker ZX300.1 Subwoofer Car Amplifier is great.
For the money the L5 is the best sub by far. Then it would be the CVR series.
