4 ohms, 2 wires?

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 . 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.

[tibby01]

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.....

[tran_nsx]

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.

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. 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 , and from experience i have had all three types of enclosure.

again read and learn.
