So I'm looking to put together a decent system for my truck, and the more I look around, the more I realize I don't know what I'm doing.

So to start off, I currently have a pair of these, which I definitely plan to use. I need to replace the 4x6's in the dash, and was thinking with going pioneer again, as the ones I just linked to are really nice, and quite affordable... but I'm open to suggestions.

As for subs, I'm thinking about using two of these. They're normally 70-80 bucks a piece, but I found them for $40 a pop (still get the 2 year warranty too). Open to suggestions on subs as well, but this is what I'm looking at for now.


As for a deck, I don't really know what to get... or what I need, rather. The two Pioneers I have now are 300W max, so I'm guessing I need a deck with 200-250W? I don't wanna push those speakers to the max, but at the same time I still wanna hear them xD

And then comes the part I know nothing about... an amp/capacitor. First off, do I need a capacitor for something like this? If so, any reccomendations?
And for the amp... since I'll have two subs that are 1000W max each, I'd need an 1800W amp to push them to the max, right? (assuming the deck is 200W)
Also, does an amp split the watts between speakers? (ie, an 800W amp would give 400W or 800W to each speaker?)


Sorry for so many questions, but if I'm gonna spend a decent amount of money on this I wanna make sure I do it right

The capacitor saves your battery from being drained. So, for pretty much any sound system you should get it. Or you can get a spare battery and run it off that. I've seen both setups, but can't really say what is better.

An 800 watt amp will put out 800 watts. The more speakers you hook up will split the amount of power you get. Thusly, an 800 watt amp will give 2 speakers 400 watts a piece (ideally, but 1 speaker could demand more power, and thus take it).

Don't forget you can tune amps. So if you have an 800 watt amp at max it will put out 800 watts. However, you can tune it to put out less wattage.

Mmk. Where do ohms come in to play? On all the amps I see it'll say like:
600 Watts x 1, at 2 ohms <= 1% THD+N
300 Watts x 1, at 4 ohms <= 1% THD+N

So the more ohms, the less watts.

Ohms measure resistance. So the more Ohms the less electricity can flow.

So there would be no benefits to using higher ohms, it just lets you adjust how many watts are being put out, right?

You can't control the Ohms. Its a property of the circuits and wires.

Ok I get it now. The subs I want are 4 ohms, so I need to look for an amp that puts out like 1600W at 4 ohms... man, this is gonna get real expensive real quick.

You don't have to match Ohms, they're completely independent of your build.

No, I'm saying the subs I want are 4 ohms. If I get an amp thats 1600W max, its not going to be 1600W at 4 ohms, so I need one that will be 1600W at 4 ohms.

Explain? I have no clue what you're talking about.

Ok, take this amp for example: link
If you hook 1-2ohm speakers up to it, it will push out the full 1000W, if you hook up 4ohm speakers to it, it will only push out 700W
