hey can any one help me out with how to bridge my 2ch amp? so I can pump the full 980 rms bridge to my subs.

 

connect the - on one channel and connect it to the + on the other channel.

BUT make sure the final impedance is not too low for the amp to handle. most amps are only stable down to 4 ohms when bridged. i'd double check the amp's specs before bridging.

 

so pretty much you just connecting the negitive wires from both subs 2 one channel of the amp and the postive + wires from the subs to the other channel??? is that correct? So it has nothing to do with the rca or anything like that?

 

if you are trying to run 2 subs. i dont think you should do it. i could be wrong. im sure someone will correct it, if im wrong.

 

yea that all........ check the amp by the terminals sometimes they have lines marking the bridge mode.....

 

i dont think i saw that on my amp but i'll check again for somethng with bridge on it. but i know its possible to run 2 subs on a 2ch bridge isnt it? i wasn't sure how to wire it, but i was always thinkin it has something to do wit the damn rca wires but i guess i was wrong but ill try that negitve to negtives and postives to postives on seperate chanels.

 

If you tell us which subs and what amp it is it would be alot easier to tell you how to wire it up, or if you should even do it

 

the amp is a power akusitic 2 ch , and the subs are 2 rockfords competions, i'm not sure of the model on the competions but they are about 2 years old or maybe more. i think they are h2's if memory serves me rite.

 

the amp has these settings,

980W peak power, bridged
560W RMS (continuous) x 1
280W RMS (continuous) x 2 @ 2 ohms
220W RMS (continuous) x 2 @ 4 ohms
3-way protection circuit
Full selectable crossover: 50-500Hz high-pass, 30-500Hz low-pass
Variable bass boost up to 24dB and variable 60Hz-200Hz subsonic filter
Stereo or bridged mono output; tri-way capable
System distress indicator
4-gauge power/ground connection
Diamond-cut heat sink
Gold-plated RCA connectors
Top control panel
Frequency response: 10Hz - 30kHz

 

it's ok to bridge an amp to power 2 subs, but the final load got to be within the amp's tolerable range.

do you remember if the subs were HE2 or HX2?

 

I know its competitions I think it's hx2 , I'm not sure I'll have to check them again. they are 12" subs and i think they push about 300 -400 rms each

 

they are currently pumpin out nicely with 2ch no bridge with half gain and half sub sonic. but I was wondering if i could bridge them out and see how it would sound, when i put the gain all the way up it doesn't sound any different really so i'm assuming that the amp isn't pushin out enough to each sub.

 

the HX2 can handle around 1000 watts (thermally at least). if they can only take 300-400 rms, most likely they're the HE2's. if i remember correctly, those are rated at 400 rms, 800 max, and came either in a 4 ohm or 2 ohm dvc.

we need to know what version sub you have so we can see if bridging is the best option.

 

Okay so I checked the subs again and i have hx2's 12" subs from rockford. So do you guys think I need to bridge the amp or just leave it with the 2 ch setup?

 

are they dvc 4 ohms or dvc 2 ohms? it should say on the magnet.

 

ill check that later when i get home. i have to open up the box and look at the magnet.

 

All you're wiring needs are dependent now on whether the subs are dvc 2 ohm or dvc 4 ohm.

If they are 4 ohm take both of the +'s on one sub and put them together on the terminal on the box. Take both of the -'s from the same sub and put them together on the box's terminal. Do the same for the other sub. Now take the + on one terminal, connect it to the - on the other terminal, then take the open + to the amps + bridged channel, and the - to the amps bridged - channel.

You could also take both +'s from one side of the sub to the terminal and do the same with the -'s then run them to one channel of the amp (not the bridged channel, just the left or right) and do the same with the other sub. This will essentially be the same as running you're amp in bridged mode since both terminals will see a 2ohm load. But ll of this is a moot point if the subs are 2 ohm dvc.

If it is a dvc 2 ohm these are you're options, and really none of them would yield safe results, or the result you're looking for. http://www.rockfordfosgate.com/rftec...5&image=Submit

 

nismo: If it is a dvc 2 ohm these are you're options, and really none of them would yield safe results, or the result you're looking for.

---why would the wiring for 2ohms be unsafe or not the results im looking for?

 

well for 2ohm dvc subs you're resistance would be too low for the amp to run safely.

 

AH.. I C well should i get a different amp? maybe a mono? or should i still try the bridge i know this amp works i have the same one in my other car with 2 rockford 12" but they are like h1s or something. they aren't anywhere as loud or as powerfull as these subs that i just got now the hx2's look like a serious sub. I'm looking for somethin to bang out nice bass. I'm not looking to losen my car bolts if ya know wat i mean.

 

okay i have dvc 2ohms for my 12" hx2's. whats the best wire up and best setup for the amp? should my 2ch amp push these subs?

 

You'd have to wire it like this

 

yea i was looking at that diagram before
but wouldnt I wire it at a 2ohms? instead of 8 ohms?

 

and how do i wire 2 subs that are in different boxes together? how would i run the neg wires from one sub to the other? can some one plz help me out on the setup

Please do some reading to feed your brain before you ask even more questions that have essentially already been answered.

 

okay heres an update, I'm losin that 2ch acoustic cuz it's not goin to work cuz its 4ohm. so I'm goin to be gettin either a mono power acoustic that will push 900rms X1 @2ohms or 1100rms x 1 @2ohms. both amps are pretty cheap they go for about 200.00 - 250.00. So what do you guys think about these amps ? will this be a better setup i know its goin to be much more stable and I'll have about 450 - 550 rms goin to each sub so thats goin to give me about 70 - 80 % the rms that they need to pump nicely. any comments or suggestions on any other mono amps would be great thanks.

 

Its PowerAcoustik and you get what you pay for, so please dont believe you will actually get their rated powers. Aside from that, the nunbers are all peak ratings.
Spend the money and get a good solid reputable amp, that will hold true to its numbers.

 

AND you need an amp that is stable to 1 ohm to push the most out of it and the subs, since they are DVC 2ohm subs.

 

question how would i wire the subs to be at 1omh? I see on the website I can go as 0.5 omhs but not 1 ohms. these subs supposedly can handle 2000 watts peak and 1000 rms each so I have 2 of them I was told by the Rockford tech I needed to get atleast a mono T1000.1db to push cuz i can get 750 @ 2oms and 1000 @ 1ohms. but thats a $400 amp and I don't think I need to spend that much on an amp to have these subs pound nicely. So i figured I can go with an Acoustic (much cheaper) either A2400db which handles 1400 @ 2Ohms or A3000db which goes 1800 @2omhs. both for about 250.00 - 280.00 shipped. and they are 1 omh stable...

 

You're not reading anything we're saying and doing what you want anyway, so just go buy your piece of crap Power Acoustic and hook it up.

Have fun.

 

I'm not even going to waste my time anymore. Take it to a fuggin shop.

 

1. you can't get them to one ohm because they're dvc 2. Look here

2. you don't need to send gobs of power to make a sub loud. the box plays a big role.

3. READ our responses before you post!

 

why are they crap because they dont cost $500.00 dollers or is it because they sell them at best buy or both.

 

They are crap because they are prone to failure, don't put out there rated power, and are made with low quality components.

What more do you need to know?

 

I'm not questioning their SQ capability (although I'm sure that is lacking too), rather they cannot be counted on for their reliability and longevity. I don't know about you, but when I install something, I don't feel like replacing it in a year's time ... I'd rather leave it installed and not touch it.

 

what the deal here. I asked for a simple suggestings if you had one on an amp other then a Power acoustic. But yet you have not given one. I am reading the post but you don't seem to know how to explain something very well. If you don't want to help then don't. I got the subs hooked up rite now at 2ohms. I'll know you cant make them into 1ohms because they are dvc 2ohms. I will however put them at .5 ohms when i get my mono amp so they will be able to be 1 ohm stable.

Please dont get frustrated with something as little as a simple question about a good amp. If you don't feel that you can help or don't want to then by all means don't.

 

your new amp will be below 1 ohm stable? not many can do that...

 

I dont think i will do the .5 ohms because that goin to be too much power or more power then I'll need to pump these subs the right way or the way I want them atleast.

 

You still need to do some reading. There are many good sources to learn about this stuff and you are not taking ANY time to learn and educate yourself about it.

 

i've been reading up and i've learned and now understand a lot more about amps then i did before. I thank you guys for keepin up with the thread. I appreciate your comments and thoughts.
