so im looking to put 12's or 15's in the trunk what do you guys suggest,
here is a 15 setup im looking at, http://cgi.ebay.com/2-Kicker-CVR15-CVR-1...1QQcmdZViewItem
i like this because it all comes together and its all and easy setup, then there is this thing, http://cgi.ebay.com/ebaymotors/PAIR-15-W...140199666QQrdZ1
i dont know what farad cap is??? what does it do, should i get that setup and make have someone make me a custom box??? is that really good right there?

here is the 12's

i like this because it comes all setup

now my big question is, (by the way i just found out what a farad cap does, takes strain off the battery) what do you guys recommend about power vs. quality??? Those first 15's have 2000W each, is that a lot? It seems like it, the 12's are just 1000 each, do you guys recommend finding something with a smaller wattage? or just because i will have the subs hooked up to it, i should leave the the higher watts for more bass? what do you guys recommend

a farad cap is a butchered rename of an electronic device.

Farad is a measure of storage of a cap. A cap is just short for capacitor. A capacitor is what whines in your camera in order to power the flash. It charges and holds electricity until told to release it. When it releases the energy, it does so all at once. Thats why it is said to be good for high-power subwoofers. It provides the electrical current to push the sub to it's full potential.

Yes, it does take strain off your car's battery by not making the car push so much all at once. Instead, the capacitor gives the battery 5 seconds to charge that 6 volts needed to push 2,000 watts. Our cars are a 12 volt system. Take away half of our juice, and you're just inviting problems.

All numbers (aside from system voltage) are arbitrary, and not intended to be at all accurate.

GP GT Guy! What kind of sound u going for?
If u looking at rattling the dishes off peoples houses as u drive by then go for the 15" these subs car such a low base u cant hear it very well till u get away from the car!! I Prefer 10's my self, but I do have a pair of 12's in my one GPAnd they Thump the Rap and Techno just right, but I still find them alittle too bassy when pumpin some rock.
And u know what 1000 watts each is plenty, good luck finding an AMP to push that out. I would get a CAP though saves ur system alot.
So it all depends on ur music choices!!

Richard ... I would like to say about the CAP it is mainly to absorb spikes that come across an A/C (alternating Current) System and fills the void when the big draw(bass spike) occurs. If u do not have a cap u will notice on high volume lights will dim with the beat of the music.
And yes they hold a voltage charge and should not be played with lightly. Its not the Voltage concern but the Amprage, most CAPs hold over 2000 amps..OUCH

One of these days, I will really get to know my job that well. Thanks for fillin in the blanks for me.

15's are too much for my liking

i have 2 CVR with a 750 watt amp 12's and that is a lot of bump.

and btw, im not an old man who says everything is too loud. im 18...lol

Capacitors absorb spikes over DC systems, not AC. Its smoothens it out and provides the extra juice when the battery can't.
Capacitors in AC systems are for phase shifting or power factor correction (saving instustrial customers on their electric bill).

You also can't really say a capacitor has a certain amperage capacity (only a short-circuit amperage rating could be given, really), since the amps flowing will depend on the type of load its seeing... and the energy (in joules, or watts/sec) depends on how much current per length of time.

It all depends on what kind of music you're listening to and how loud you want it.

For me, a single Infinity dual-coil 10" is great for rock, but I don't blare it (played drums a long time mostly without ear protection, so I'm being careful now).

But also, if I'm setting up a sound system for a band, I prefer 4 18" subwoofers, and 4 15" woofers... system is somewhere in the range of 12,000 watts of max handling (amplifiers throwing out about 6,000 watts). No wonder I'm losing my hearing.

GP GT guy- heres the pics you requested

I have a pair of 10s and it's good enough for me.

i have one 12 with 400 watts ... and that is way to much for me ... i would be happy with a good set of componants

As Zulu corrects me, I bow and give thx, my mouth opened faster then the file on Capacitors.
Thx Zulu

It's actually Zuul. You know, from Ghostbusters.

whoa, that's where you name came from?

Actually zuul, I have a question.

Capacitors in parallel add their capacitance. Would running 2 half farad caps in parallel hurt anything? 1 farad caps are expensive as heck and don't get me started on 2 farad caps with a digital voltage read-out.

I figure if it works I'd like to run 4 1/2 farad caps in parallel as it may end up being cheaper...

Where would you need 4 1/2 farad cap?? what do you plan on running??
