what amp for 2 12 inch kenwood subs?
[Question]
I have 2 12 inch kenwood subs that are 1200 watts each. (400RMS watts each). excactly what kind of amp do i need? how many channels and how many watts?

get an amp to blow them up cuz kenwood subs suck



but get a mono class-d amplifier that puts out 800rms watts @ 2 ohms



wire those subs into 2 ohms and there ya have it, the amp will push 800rms to that single load which will be putting 400rms to each sub

edwards1337 @ 2009-02-20 10:25:26

id return those, if you want some cheap subs that actually sound good I would get some kicker cvr's.

Fishmasta @ 2009-02-20 10:36:17

A kicker zx400.1 will push those subs just fine. They arent the most expensive subs but that amp will push them and they should sound good for what they are.

adam m @ 2009-02-20 11:17:36

you need a mono block amp at 800 wrms! you didnt tell us the ohms!



When you know the ohms look at tihs link to tell you what load you will need to put on your amp

Best amps i have found are Rockford, JL audio and Directed



cheaper are JBL, Hifonics and Pioneer

Car Stereo System Question.?
[Question]
If I buy, two Kicker CVX12 speakers and put them in my car. What kind of amp should I start thinking about buying? Or what if already have an amp (ZX.1000) can I buy another one or should the one ZX.1000 be able to hold both of those speakers? Just wondering. If anybody can help be appreciated. Thanks.
They are the dual voice coals. Yeah they are 2 OHM DVC. So even if the amp's are 1-Mono they will still work? I guess I'll have to get rid of my ZX.1000. :-(
I meant if the amps are one channel sorry.
So the ZX.1500 would be a good buy if I am looking to build this sytem? Should I be thinking about buying an optima battery and I have a stinger 5 (Farad) capacitor. Good thing to keep?
Well see, the current system I have is a Kicker L7 (1500 Watts / 750 RMS), Stinger Cap (5F), ZX.1000. Everything under the hood is stock (Battery, Alternator and Wires).



I have been looking at the Big 3. See in the summer I was going to go with 2 L7's but funds ran low. I had already had a ZX.2500 in my hands but just couldn't get that project off the ground. My current L7 is refurbished but has been acting up so my warranty covers the full price.



So the cap does me no good for this system? Because everyone told me that it would help with the L7. Just curious. I am trying to keep everything within a budget but I know if I really want this system I should just do it the right way and not half it.
lol. well I purchased it on ebay (Refurbished) and got a square-trade warranty so I am getting my full $121 back for it. =) Thanks for all you help bro!
It's a 12". I've had it since July. Sucks I had the other one and had to re-sell it on ebay for 90. =/ and the guy gave me negative feedback for no reason.

If you already have the ZX 1000.1 then it will work you will just be a little short on power.

If you have to buy an amp then the ZX 1500.1 would be a better match.

Either way you go just be sure to buy the 2ohm DVC version of the subs.





Edit,

george just so you know smartass,the reason i told him to get the 2ohm DVC subs,is was he is wanting to run two subs with a kicker amp,and those amps are not 1ohm stable.

So know what you are talking about before you put somebody down,cause it looks like you do that alot.

wishmaster @ 2009-02-20 09:52:34

Wishmaster get a clue before you speak about things you do not know.

If your getting 2 of these subs, then get the DVC 4 OHM so you can wire them down to 1 OHM. Follow the link for an easy to read wiring guide to help you wire them down to a 1 OHM load to your amp:

http://www.edesignaudio.com/wiring.php

If your only getting 1 sub, then get the DVC 2 OHM sub. Wishmaster needs to make a wish to get a clue before he talks about things he knows not.

georgewillings @ 2009-02-20 10:09:27

those subs pound, i am getting the 2 ohm dvc ones, a pair and running that @ 2 ohms



sell the 1000.1 and get the 1500.1



wire those subs into a single 2 ohm load and you will be giving each sub 750 rms watts



or get any amp that is 1 channel and puts out 1500rms watts @ 2 ohms



do it this way and they will pound trust me



and no, dont get the 4 ohm dvc and wire them to 1 ohm, even fit he amp is 1 ohm stable it wont last half as long because it needs to work harder to push power out because it is 1 ohm... trust me



an amp that pushes out 1500 watts @ 1 ohm and an amp that pushes out 1500 watts @ 2 ohms will be around the same price + or - 25-50 bucks will be no different

what would you want a capacitor for?



A capacitor is only good so far as the audio system isn't trying to pull too much from the electrical system. A cap doesn't provide more power, it's designed to 'stiffen' the voltage to the amp, nothing else. If the current isn't there, a cap won't help. The alternator must have at least 20% more amperage power than the entire vehicle and sound system combined for a cap to be of benefit which is ironically the same requirements for an amp to be efficient. A cap does it's best to keep the voltage at a certain level, but if the voltage changes so will the cap voltage. The cap just makes the change smoother. The diming light syndrome isn't a voltage issue but rather a current (amperage) drop. The voltage simply follows what the current does. A cap does not help this situation at all. A cap doesn't provide more power nor does it try to correct it.



therefor a cap will be useless for you



you will want to upgrade the big three



heres a link to it:



http://forum.sounddomain.com/ubbthreads.php/ubb/showflat/Number/312025/page/1







you will want to you use 1/0gauge wire for this



you should also *if needed* look into a HO alternator, one that puts out at least 200 amps, 220+ would be great, and if you upgrade the alternator you should then get an optima yellow top battery





__________________________________



well if you have the cap you might as well use it, are you getting that l7 fixed by sending it into kicker? if you are, ill gladly purchase it from you.. lol



but anways if you have the cap you might as well use it, it will be able to stablize the power drawn from your amp from your electrical system, but most people think caps are used to fix dimming lights and such, which their not... but if you have it you might as well use it, its not gonna add more power or anything but it will help smooth out the voltage being pushed through your amp



_________________________________



what size sub is it? either way 121$ is cheap lol.. your welcome



_____________________________________



lol, yeah but 2 12" kicker cvx subs will pound a lot harder than 1 12" l7 2 cvx pound harder than 1 15" l7

Hi, if you want to get more information about it, go to http://car-engine.synthasite.com/?q=sony%20cd

Welly A @ 2009-02-20 10:21:10

you can do it with a fm modulator.

Fishmasta @ 2009-02-20 10:37:28

does the cd changer have power (ie do you need to hook up power to it from the head unit?)

You need a mains 12Volt DC 30Amp Power Supply.

Derke N @ 2009-02-20 09:30:10

They other guy is right, but you may need more than 30 amps



i have no idea where you would get one from!! but its what car audio stores use to give demos!!

Jim Jimmaaay @ 2009-02-20 10:17:40

you need a 12v supply or transformer. You can get one off the inrternet or from wilko or somewhere like that

Can I connect my flash to car stereo through aux input?
[Question]
I have a Jensen cd/mp3 player in my car. Can I connect my 4GB flash USB drive to my mp3 player through an aux input? If so where do I find this type of cable and what's it called?

no, u need to buy a strereo with a usb device hooked up to it. they cant read usb unless it is installed in the guts of the stereo. The link is to the stereo I have in my car. It cost me about $250 Canadian at a store where I live. It is USB. Get rid of that Jenson, they are garbage.

DEEZ NUTZ @ 2009-02-20 09:03:59

Depends on what MP3 player you have. Jensens should come with a USB port on them. If they don't, go to a car audio shop and get one, or look on ebay. I know of one where it connects into the AUX port and you can connect a USB to that. I'm sure thats what you're looking for. BUt name I don't have a clue. Just google it. Google has every fucking thing under the sun, should be able to find it.

mugzy91215 @ 2009-02-20 09:04:04

I believe the aux input is analogue - a USB input is digital. I do not believe you can run one through the other.
