i need an amp and don't know where to start?
[Question]
here's the specs on one sub, im getting two and i have no idea where to start with amps or wiring someone please help?



* Sensitivity: 91 dB

* RMS Power Range : 250 Watts

* Peak Power Handling: 1000 Watts

* Impedance: 4 Ohm

* Low Frequency response: 20 Hz

* High Frequency Response: 114 Hz

* Diameter: 12 Inch
if i get a monoblock do i need 2 or 1

is that the proper way to wire it?

and if you could give me some good amp wire kits
sorry about that i didnt even look at the picture.... =\



heres is a link to the sub:

dont look at peak, it means nothing



look at rms watts



get a mono amp (1 channel amplifier) that puts out 400-500 rms watts @ 2 ohms





the last guy is an idiot, lol under powering a subwoofer cant harm it one bit, so he is basically by saying that, having a stereo at low volume is bad for a sub woofer.. thats the same as having it under powered because when the volume is lower, the amp isnt feeding the sub as many watts as it would be



and no, clipping and fried voice coils are from OVERPOWERING subs.. idiot.





________________



you will only need one amp



heres a few:



MTX JH300 --- 400 rms watts @ 2 ohms

Kicker zx400.1 --- 400 rms watts @ 2 ohms

alpine mrp-m450 --- 400 rms watts @ 2 ohms





those are just a few examples just get an amp that does 200-250 rms watts @ 4 ohms



_______________________________



you didnt specify if your subs were 4 ohm svc or 4 ohm dvc so we cant tell you hwo to wire them, when i told you the specs to get from an amp i was assuming they were 4 ohm SVC the link you posted is how to wire 2 2 ohm dvc subs to a 4 ohm load



if they are single voice coil subs (1 pair of terminals 1 red, 1 black) wire them like this:



http://akamaipix.crutchfield.com/ca/learningcenter/car/subwoofer_wiring/2SVC_4-ohm_mono.jpg



it will present a 2 ohm load, which is where what comes in handy what i was talking about earlier.





_________________________________





wire them the way i showed in the link above then, and get an amp to the specs as i have said, not 600rms watts you will over power them which isnt good, underpowering a sub is the same as having the volume turned down.. cuz if the volume was down and an amp was feeding a sub its full watts.. wouldnt the sub still be blasting all the way over the music? yup.

A very informative website, kindly stay in website and check

Phoebe P @ 2009-02-18 20:29:57

You should look for an amp that has 600-750 watts RMS. Yes that is more than the rating on the subs. No that isn't a bad thing. Running a slightly larger amp than necessary will allow you to turn the gain down slightly and achieve more dynamic bass response. Specifically it is referred to as dynamic headroom. And contrary to what all the MORONS out there say, it is way better to overpower than under power. Most fried voice coils happen when an underpowered sub's voice coil is hit with clipping(when the amp runs out of power) This heats up voice coils and can ultimately result in failure. Clean power offers more control over the voice coil, more accurately reproducing the sound waves and provides better cooling for the voice coil as the cone is more efficiently moving.

Patrick H @ 2009-02-18 20:32:53

since you're getting 2 subs, you can get a single monoblock amp, that's ~500 watts rms at 2 ohms. You could also get a stereo amp that's 250 watts rms at 4ohms. have fun!

my capacitor stays on when i turn off my car help!?
[Question]
i installed a cap in my car and did it the right way i suoppose.

batt to cap to amp

and cap to gnd and amp to gnd.

it powers up real nicely and works great but when i turn the car off the amp and subs and everything turns off but the cap stays on for labout five min and then turns off. a few min later it turns back on again. i do not know of my cap has a REM slot so i can plug it into my stereo so it turns off. how do i go about fixing this

the cap is a power acoustik 3 farad cap the old style i think

The capacitor stores a significant amount of charge. It stays on until it drains the charge down. You'll probably find that it will stay on even after being disconnected.

Marc R. @ 2009-02-18 21:39:37

those led's usually do stay on. there's nothing wrong with it. remember back in science class when you plugged that little led clock into a potato? that's how little power it takes to keep the led's on, so you don't even have to worry about it draining anything. i've kept mine hooked up while i was out of town for a week and everything was just fine when i got back. just keep enjoyin your stuff man

Bill D @ 2009-02-18 21:51:49

its gunna stay on till it drains, your battery that is lol

ooxj2000 @ 2009-02-18 22:12:35

The cap isn't "on" or "off". It is simply the voltmeter on the cap that turns on and off. It will do this until the voltage in the cap stabalizes with that in the battery. If any changes in the voltage between the cap and battery exist it will turn on.



The current draw from that is so small it will not hurt anything. It is made to do that and is perfectly normal.



Good Luck!!!

how do you take out the fuses in a car audio amp?
[Question]
theres holders that the fuse is in and i cant get them out. do i just force them?

Brandon @ 2009-02-18 20:46:33

[All Answers]
just take a pair of pliers and pull them out, it wont cause damage to the amp or fuse

edwards1337 @ 2009-02-18 20:49:48

if its a maxi fuse thereshould be allen screw but if there blade fuses yeah just use pleiers dont pull to hard tug and shake em a bit they should come right out

evil dude @ 2009-02-18 21:10:28

take a pair of needle nose any try to pull it out that way it is okay to force out just be sure not to brake the fuse off in the radio

What should I get, a 2-ohm or a 4-ohm sub. Which is louder/more bump?
[Question]

Sharolyn @ 2009-02-18 19:57:32

[All Answers]
no difference



only difference is one has a lower impendance (2 ohm dvc sub) than the other (4 ohm dvc sub)



which means a 2 ohm dvc sub on a 1000 watt mono amp will draw more power from the amp than a 4 ohm dvc sub would



a 2 ohm dvc sub on a 1000 watt mono amp will grab the full 1000 watts from the amp, while a 4 ohm dvc sub will onyl grab about 500 rms watts from the 1000 watt mono amp



if you are going to get dual 2 ohm dvc or 4 ohm dvc, you can only wire 2 4 ohm dvc subs into either a 4 ohm load or a 1 ohm load, and dual 2 ohm dvc subs you can wire into 2 ohms







_____________________________



edit:



actually the last guy is wrong, it is CHEAPER to find an amp that puts out a certain amount of watts @ 2 ohms than 4 ohms



say you have a 1000 rms watt 2 ohm dvc sub



it is cheaper to find an amp that puts out 1000 rms watts @ 2 ohms rather than 4 ohms



heres an example



an amp that puts out 1000 rms @ 2 ohms costs an average of 150-300$ it puts out 1000rms @ 2 ohms



an amp that puts out 1000 rms watts @ 4 ohms costs an average of 450-600



its easier for an amp to put out more watts @ a 2 ohm load rather than a 4 ohm load..





take a look for yourself

edwards1337 @ 2009-02-18 20:02:59

No Sound Difference It Jus Gives You Different Ohm Loads. ie Two Dual 4 Ohm Subs Can Be Wired To Be Either A 4 Ohm Final Impedance Or A 1 Ohm Final Load.

~Will~ *Xxclusive* @ 2009-02-18 20:08:41

...so basically, what theyre saying...if your amp can handle a 2ohm load, it will be louder for the money$$. (more power) but the sound quality is the same no matter what - at same wattages





edit:

I never said anything about amp prices....Ur talking about something totally different, and show me a 2ohm 1000w rms amp for 150$? please. ur obsesed with poor sound quality, and overpowered systems, keep it clean first then step it up as your budget allows. 1000w rms in a jeep will not only damage ur ears, but rattle the hell out of the car inside and out.
