Im up grading my system, changing out all the door speakers, and tweeters. I already have one 15 and I am adding another one. I am running the door speakers off a 1000watt amp and the two 15's off a 3000 watt amp. I am new to this, so I was wondering, do i need a cap? Is a cap a cap, or does name brand really matter?

 

Do the "Big 3" and if that is not enough, get a bat cap

 

what amps? highly doubt you will see 4 kilowatts with a stock charging system.

 

whats the big 3?

 

what do you mean you doubt I will see 4 kilowatts with a stock charging system... sorry im dumb when it come to this, where does the 4 kilowatts come from? please explain this

 

also do you guys think i would need a crossover?

 

your amps are not 3000w and 1000w.
There is absolutely no way.

Those numbers are complete bs.
I dont expect your speakers to be more than 200,300w rms at mooost
same for sub....

list your model #[s] and make[s]

 

It's so amazing how people fall very easly for the bull**** numbers they see...True music @ 1000 Watts = VERY, VERY loud and powerfull...And I don't think you can acomplish true 1000 watts RMS with stock charging systems.

 

Alright, well, since you're running 4kW you are going to need to get some 00 AWG wire in order to power those beasts. You will likley need a mucher higher rated, dedicated battery AND additional alternator to provide power to the amps. I would recommend starting to look into how to run a secondary alternator because, afterall, you are going to be running w/ 4000W

 

1kw is doable, 4 on the other hand will need some work to accomplish.

 

Where can I find the belt splitter/custom bracket for second alty? PLEASE HELP.

 

I know its not 4000 watts rms, I never said it was.. Im just trying to get some general info here..

 

You are running that much power and don't even know if you need crossovers? C'mon do some reading and research that will go a LONG way.

 

Also, if you tell us what products you're running we can further assist in what additional hardware you'll need.

 

What's the maximum current draw for the amps you selected? Giving the max watt number is completely useless. You never know how the amps were rated and not every amp has the same efficiency. Whether or not you need a crossover is up to you. You could possibly send all frequencies to all your speakers if you really wanted to since you gave us no information about your system at all. I suggest you do some research before you start throwing your money all around.

 

Way to dodge. However you did say this...

Post product specs or I call on the whole thing.

 

i love how everyone jumps on the guy assuming he means one thing when he actually says something completely different.

is there really "no way" that he could be using a 1000 watt amp on his speakers? let's do the math, shall we.

we'll take your average 1000 watt 4 channel amp...
that's 250 watts per channel at 2 ohms...
or 125 watts per channel at 4 ohms...

...but wait, who would actually send 125 watts to each speaker, right? no one on this forum would actually want their music to be able to get loud...

but what if he has 8 ohm drivers? that means he's sending 62.5 watts to each speaker...impossible, right?

he never did list his setup, so you guys have no idea how many drivers he's even using. that changes the math even more.

before you guys go jumping down somebody's throat, read what he actually says. he's using a 1000 watt amp. he doesn't say he's sending 1000 watts RMS to each speaker. there's nothing wrong with using an amp that will provide more wattage than you need as long as you have your gain settings set correctly. it's called headroom.

efficient...no. possible...yes.

 

DAMN!!! thats all i got to say about that!!!

 

 

You're assuming that this is true, he may or may not have that kind of amp. Most of us asked for more information, and many of us know that the electrical system of our car is not capable of supporting a TRUE 4kwatts.

Now you're 8ohm speaker argument isn't valid either since he has yet to tell us what products he has. He said he has 1000 watts not 62.5 watts to each speaker. WE must go on what he said, not the assumptions you made. Plus there's not many 8ohm interior speakers unless you piece together your own setup.


All in all, everyone needs to wait for him to describe what he has. And he has failed to do that repeatedly, thread should be locked and/or deleted.

 

yes, i made my own assumptions on what he actually said. but that was just to counter what others had said. i was throwing out possible scenarios. i was trying to show that even though most people wouldn't do it, someone else might. i don't want to argue. my point is simply that, aside from the regulars on this forum, there doesn't seem to be much help. a person new to car audio comes on the forum looking for help and gets greeted by people throwing up bs flags. if that were you, would you come back?

 

Fight nice kids.

 

Um when I was a noob I read the stickies, I'm not a noob (as much) anymore.

If someone had done that they'd have most all the answers they needed.
