4 ohms, 2 wires?

Now that your here.........

I have an alpine sub that has 4 places for wires to connect, but I only have 2 wires to be connected to them and connected the two as they should be, and the amp is connected as it should be, but I don't get a power light on the amp. I have a wire tester and the light came on for all the wires. I tried my old amp and still got no power light. this is the only thing I can think to be wrong. Everything is hooked up according to the three manuals that i have (the deck, amp, and sub ones) but I cannot find the problem

any help would be appreciated

Here's what I have:
Pioneer deh-1000 deck
Alpine SWE-1041
Sony XM-280GTX amp (the 480 watt version)

All of which is in my 88 crx hf

4 connections? their should be only 3, one for the power, one for the ground, and one small wire for the turn on/off signal. maybe your getting confuse with the 4 speaker connections? it would be a lot better if u have a pic.

ok i can see the 4ohms, the 2 wires, but where is the lesbian?

j/k

yeah there should be
~ A large power cable connected to battery
~ A large ground cable grounded somewhere
~ A small wire going to the back of your deck, usually connects to the power antenna lead ( small blue wire in most) this is what turns the amp on and off when the deck is turned on and off.


Then all you have left is you speaker connections, and the signal cables.

Everything is hooked up to the amp how it should be(I think), but i have no power light.

Yes i am talking about the 4 connectors to the speaker, i only have 2 wires, is that a problem?

Why don't i have power, all my wires are good (tested with wire tester) and they have electricity running through them, except the blue wire (labeled REM), but power is through it when the key is in the on position

oh yeah, i almost forgot, the lesbian was to draw you in, and it worked!!!!

what signal cables are you talking about? The RCA wire?

Does the ground have to be directly on metal, or is it okay on a painted surface, would that make me have no power?

yes it has to be on metal

I have pics, but geocities is being gay, i can e-mail them to you if you want to see....

update:
ground cable is on metal and i now have power (light), and the sub moves a little bit (my 6.5's move more) what else could it be?

I'm just guessing here, but maybe you got a blown fuse somewhere. I have two fuses on my amp and when one blows(usually both will blow at the same time) my subs sound weak and strange. Hope this helps.

Problem solved:
The ground was why the power didn't come on, it was on a painted surface before, now it is fixed.

And as for it not hitting as hard as i want it to, I had to adjust the little knobs where all the wires are plugged in.

Thanks for all the help guys, I will be off enjoying myself as i go deaf now.

I got a question for all you guys though, I get the idea that his sub has 4 terminals on it, but being the SWE 1041, they have a D at the end on DVC subs right? so then is the extra set of lreads from the SVC to help in the wiring of multiple subs?

i don't think the extra terminals on the SVC are wired to anything. My previous audiobahns all had 4 terminals like they were DVC, where as they were actually SVC. I guess it's cheaper and easier to just mass produce the same basket, then to sit there and make 2 terminal baskets for SVC and 4 terminal baskets for DVC subs

what audiobahns did you have. did you like them, I got an ALUM12 coming now, i had the high excursions and liked them alot. sounded just as good as my friends punch HX2 that he spent 3 times as much on, I also had less into my amp as well. lol

since u seem really new to car audio, i just want to ask if u got ur amp bridged to your sub? this will give twice the wattage and in some amps even more.

uhhh dood, you cant bridge a sub and amp...you can wire it in parallel though.

uhhh dood, you cant bridge a sub and amp...you can wire it in parallel though.

what are u talking about? yes u can bridge an amp to a sub, it usually say what terminals to use to bridge on the speaker connection. running parallel is to use more then one sub to one connetion which will drop the ohm. when an amp is bridge it stays at the same 4ohm but turns two stereo channels in to one mono channel for the sub giving it twice the power. for example a 2 channel x 50 watts, when bridge it can produce 1 channel x 100. with some good quality amps they can even produce 1x200 watts.

you are just getting the terminology kinda mixed up. you can only bridge amps or amp channels. you can then connect the sub to the bridged load by wiring them in parallel or series.

you can wire one sub in parallel, if it is DVC.

and when you bridge two mono amps or two channels of an amp, the load the connected amps see will be lower, say 2 ohms if you bridge two channels. this is because you have two different power sources and the impedance is divided by two. hence why you see the minimum impedance rating of two bridged amps to be 4 when they can take a 2 ohm load when unbridged.

i don't have anything mixed up, ur the one saying u can't bridge an amp to a sub :rolleyes: . i just told u how to bridge an amp to get double the power and yes this is bridged. here for ur info, link on how to bridge an amplifier, it's the second to the last paragraph. there explanation is basically the same as mine, and if ur still don't get it, then i guess ur truly lost.

http://www.discountautosound.com/faq-amplifiers.htm

ughhhh....

read the paragraph in your post carefully. i am nowhere near being lost. it says....

"An amplifier that can be bridged provides more flexibility as it can be used as a 2 channel amp one day and then bridged to a subwoofer the next."

it means this (implied words in parenthesis)...

"An amplifier that can be bridged provides more flexibility as it can be used as a 2 channel amp one day and then (a) bridged (amp) to a subwoofer the next."

yes, bridging results in more power...double is usually a good rule of thumb.

but listen carfeully... YOU DONT BRIDGE SUBS TO AMPS!!!!!!!!!!!!!!!! THAT IS THE WRONG WAY TO SAY IT!!!!!!!!!!!!!!!

you bridge two amps or amp channels, and then send the bridged power to a sub by wiring the sub(s) in series or parallel to that bridged source of power. if you dont believe me, wait until someone else posts.....

hold up, u want to tell me where i said bridged the sub to the amp? dude i ask the guy if he bridged his amp to the sub, mean bridging his amp channels (which i refer to as speaker connections on the amp) to his sub. is that hard to understand or what? ur the one implying that i said bridged the sub to the amp, now please shut up and be quiet. :disappoin

christ, quit arguing. you are both just stating the same thing over and over.

christ, quit arguing. you are both just stating the same thing over and over.

yes we are arguing about the same thing as far as bridging the amplifier, but if im not mistaken he is try to impy that i said to bridge the subs, which u can't. they can only run in series or parallel.

Actually, you can bridge a subwoofer (s). Its called wiring in parallel and series. :p We just don't use that word in car audio that much.

yes ur right. i never heard of it in car audio, and if it is use then it just confuses this more because u don't know if they are referring it to be wired parallel or series.

It can be used as a general statement. Kind of like: "I have a ported box", yet we don't know the exact defintion of the ported box. Car audio is full of general statement. Some are common sense, some aren't so common. :)

maybe u don't know what the definition of a port box, heres the defintion:

Ported boxes: For forceful bass
Ported boxes use a vent (called a port) to reinforce low bass response. You get more output than you would from a sealed box at any given amplifier wattage. Some people prefer the sound of ported boxes for rock, heavy metal, or any hard-driving music. Ported boxes can deliver deeper bass than sealed boxes, though they need to be much larger than sealed enclosures to accomplish that.

as far as general statements i can't recall any beside subs bridging, but as u can see we don't even use this word, only for amplifiers.

Hey don't trash talk someone who knows more than you. After saying that. You can't say a ported box is vented. Some ported box have circular ports not vents. Not a single ported box is the same, you can't define one. They have different tuning, different size. Not necessarily louder, maybe someone has their's tuned for low end. Others' could get louder at higher volumes in sealed boxes that are not tuned so low. Ported boxes don't always deliver deeper bass, some deliver higher louder bass, again based on the tuning. You can accomplish deeper bass in both ported and sealed boxes by bigger sizes... Sealed boxes are more prefered for rock hard-driving music last I checked. Ported are just more advanced boxes and harder to perfect, they tune it based on the listener's liking, not necessarily louder than sealed boxes again. There is no "Defined ported box" that is a standard, yes they all look the same but do not preform the same. Car audio is full of general statements.

As mentioned, ported box is just one part of the puzzle. To get more in-depth, you gotta know what the port is tuned to, how large the box is, port area, cross-sectional area, etc. Ported is just in general, same as "wiring" is in general. One word does not explain all.

Perhaps you need a definition of bridge?

Main Entry: bridge
Function: transitive verb
Inflected Form(s): bridged; bridg·ing
Date: before 12th century
1 : to make a bridge over or across <bridge the gap>; also : to join by a bridge
2 : to provide with a bridge
- bridge·able /'bri-j&-b&l/ adjective


As you can see, from the definition, wiring coils (or subs) in series or parallel is also bridging, because you are linking one to another using wires. Anything connecting one to another is the bridge. The process is called bridging. Very simple.

A ported box isn't always louder than a sealed box, even with the same amount of power.

ok dude whatever the size or shape of the ports, they are still vents. do u know what the definition of a vent is? here let me help u:

vent: 1.a small aperture or passage; an outlet. 2. an emmission or discharge

i do not want to be here all day arguing with u and break your post apart piece by piece, so im going to leave u with a link all about enclosures. read and learn. oh yes this is where i got the definition of a ported box :rolleyes: , and from experience i have had all three types of enclosure.

http://www.crutchfieldadvisor.com/learningcenter/car/subwoofers_enclosures.html

again read and learn.

I guess now we have to go into the terms, Prefab and custom...
Prefab is all that crutchfield will tell you about. Those are pre fabricated boxes, prefab for short. they are boxes that are louder, but only for the woofers that are made to be louder at that note and only for the ones with that certain displacement.

Costom ported boxes- audiophile boxes, used to properly tune a subwoofer to the range you would like to hear the subwoofer in.

Since you are in love with crutchfield,
Bandpass boxes: Maximum slam!
Bandpass boxes are a special type of ported box designed for maximum slam. The woofer is mounted inside a dual-chambered box (one chamber sealed, the other ported), with the sound waves emerging from the ported side. The sound that comes out of the port is extra loud within a narrow frequency range.

Because bandpass boxes are super efficient within that range, they tend to boom. Their aggressive sound is great for rap, reggae, and hard rock. Not all subwoofers work well in bandpass boxes, though; consult our product information or call a Product Advisor to be sure.

If you believe that, I feel sorry for you. A proper description is, they have the most screwed up frequency, which is split up into multiple different areas, that sound loud but crappy.

http://www.adireaudio.com/tech_papers/enclosure.htm read that, tells you how the audiophile's approach vented boxes, not for loudness, but clarity.

since u seem really new to car audio, i just want to ask if u got ur amp bridged to your sub? this will give twice the wattage and in some amps even more.

Yes i am very new to car audio (this is the first time i have done anything with anything audio)

and yes the amp is bridged to the sub.

Thanks for your help
