How Should I wire??

I have two Tsunami GXA 4280 amplifiers and I'm planning on geting two Audiobahn AW1200Q High Excursion subwoofers. They have Dual 4 Ohm Voice Coils and are 700 watts RMS 1400 max each. The specs on the anps are 70x4 at 4ohm 140x4 at 2ohm and 280x2 bridged into 4 ohm RMS. The max bridged is 460x2 @ 4ohm. I plan to wire each sub to each amp bridged not in a series. So my question is when the amp is rated at 4ohms for the bridged output is that for the total load because the total load will be 2 ohms or is that rating for the resistance of each channel?

that rating is for resistance of each channel if I know what you mean by what you are saying...

It just says 280x2 bridged into 4 ohms for the RMS and 460x2 bridged into 4 ohms for the Max so I just didn't know if that meant per each channel or for the entire load on the amp.

It means 280 in one set of bridged channels, and 280 on the other set of bridged channels. It means 280 x 2...

I know that. I was referring to what the amp said because you replied "if I know what you mean by what you are saying" I just need to know if the ohm rating is per channel or for the entire load on the amp.

If I'm understanding it right...when your 4 channel amp is bridged into 2 channels, it is stable down to 4 ohms (280 x 2 into 4 ohms) meaning it's per channel bridged and not the entire load. The entire load will say something like...XXX x 1 into 4 ohms.

Okay good. So if I have one Dual Voice coil subwoofer (4 ohm vcs)wired to one amp bridged then my ohms will be right? 4ohms per channel with a 2 ohm load on the amp.

You should be able to run each voice coil to each channel bridged because it'll be a mono output.

It'll be 4 ohms per channel bridged @ at a 4 ohm load.

1st Channel (L). Use the positive speaker wire.
2nd Channel (R). Use the negative speaker wire.
That gets you one channel bridged. Do the same with the other 2 channels and you get another channel bridged. You end up with 2 channels bridged (280 x 2 @ 4 ohms). If you run less than 4 ohms per channel bridged, you'll end up losing your power output.

If those confuse you, here is some help. http://www.edesignaudio.com/ep2/wiring.htm
Since you have two amps, I assume you are using one amp for one sub, one for the other. Now, you will have to make sure your gains are almost exact if on one amp. same with the other, but it doesn't have to match amp to amp. Just within the amp.
"Worst case scenario is if they are wired completely (180 degrees) out of phase. When this happens, the two magnetic fields cancel each other out, causing the voice coil not to move. That is the worst that will happen. In stereo mode, there will only be a slight alternation between the two signal. The differences in amplitude of the signal will be greatest if they are each 180 degrees apart from each other. But that should never happen with muic because if it were to happen, then we can assume that the recording company did a bad job of recording. If they have done that, they would waste their (and our amp's) energy on trying to reproduce signals that would cancel each other out.

The worst thing that could happen is if you send so much power to a sub (rated at say 300w per coil) and wire it completely out of phase. Since 300w per coil is it's Pmax when the driver is moving, standing still because of the phase will burn the coil up, because there are no movement, causing the voil to now draw air in from the pole piece. But music isn't like that. Music will be dynamic and will have very little alternation. Never will it be completely 180 degrees out of phase so there is nothing to worry about.

The magnetic field is not strong enough to literally rip the subwoofer apart, even in bad situation. If you ever tried to pull each end of the voice coil, you'll see that it's going to be hard to tear it up. That is with bare hands, pulling it outwards (no bending).

please don't get audiobahn, and if i read right you will not be able to bridge those 2 channels into 4 ohms, because the subs are dual 4 ohm. that means it can only be put into 2 ohms or 8 ohms.
and i would reccomend 2 adire shivas, they are dual 8 ohm, so you can put them each at 4 ohms into the sepparte channels, they are 125$ a piece and i garuntee you they are better than those audiobahn thingies.

He has 2 amplifiers...

You can bridge the amp so now you effectively have 2 channels to work with. Attach each "channel" to each voice coil on the sub and you're set. Do this again for the other amp and other sub and that should be it. Make sure all channels are receiving the same input, to do this you'll need some y-splitters for your rca cable.

Ok good everything that I thought was right just double checking and I already got the rca splitters and everything i need. Should be all hooked up within the next few weeks! And btw I've heard the bahns that I'm getting and they're just what I'm looking for. I'm not looking for quality I just want loud hard hitting bass and the bahns are going to give me that. Ive also looked into some brahmas and are still considering them.

Yeah, the audiobahns will give you loud hard hitting bass, brahmas... MMM good

yeah, i missed the two part, anyway, i would still reccomend no audiobahn, and if you do get audiobahn, get a warranty because they have been known to fall apart and break, plus the only thing they are known for is spl(getting loud) if thats all you wawnt fine, but there is better for the money.

I'm getting a 1 year warranty with them and the brahmas while nice aren't quite in my price range. With the bahns i'm gettin 1400 RMS for under 200. But I guess Ill take suggestions of other brands to consider I want two 12's that will be loud and hard hitting to fit the two amps Ive listed above.

loismustdie, I and 3 other people I know have audiobahns fully powered to the RMS and have never had any problems with them. RMS doesn't mean volume always, bumpinstang77. Why do you want 2 subs when 1 is more than enough of a good sub. A single good 15 is better than 2 12"s of a weaker company.

you can get 2 ed12kx's for under 200$, and they come with a warantee i think.

they are better than audiobahns, i believe haibane will agree with me on that.

http://www.edesignaudio.com/ep2/12kx.htm

each one is 400watts rms, that is plenty, and if you end up getting the audiobahns, and give them their rms, i hope you have your front speakers amped, because you won't be able to hear them is my guess.

I want 2 12's because I can't fit a 15 in my trunk. And 400 RMS isn't enough my amps are each 460 RMS and I want at least 500 RMS. For my components..they will be amped I'm going with 4 6.5's and for tweeter don't know the size yet. Most likely Infinity. I really like the audiobahn look and I've heard some that are what I'm getting that sounded very good but I was also considering one immortal 12 since they have the quad vc's. I've also looked into some fosgates. Ive never heard any so how would they compare up to the audiobahns with loundess and I'm guessing the SQ is better. Haibane what audiobahn's do you have? My friend has three 18's 3600RMS and can I say damn those are loud.

you can fit 2 12's but not a single 15?
wtf?

in loudness, i would say that with the same amount of power the fosgates would be eqaul in spl, and would be better for sq, but the ed12kx's will get pretty loud with 460 apiece and the sq will be better than either, i don't understand why you insist on audiobahn.

and on your components, infinity isn't that bad, but its mainsteam so u know there is better for the money, and i'm curious are you goin to upgrade you alt. or an extra batt. or both. becuase it sounds like you will have some electrical issues if you don't.

haibane, would you really reccomend two audiobahns over two ed's?
i mean c'mon

serinity now!!!!!!!!!!

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3071014970&category=18804 That will blow your mind... I am not recommending audiobahn over ed's I just would like to go with what the guy wants. Loud unclean music. Audiobahn immortals will pound louder than ed's for the same price. I would put this sucker in a ported box if you can. otherwise seal it big. YOU CAN fit a 15" if you can fit 2 12"s. This can handle about 1500 watts rms. So you can wire it as low as possible. It is a quad 2 ohm voice coil so it should be easy to wire low.

I can't fit one 15 because of height issues my trunk is very short and even to do the 2 12's I'm going to have to make a box that angles down towards the back. And yes once I'm running at full power I'm going to get a seperate battery and a 2 farad cap. Is the reason you guys don't like audiobahn so much just because its loud but not good quality?

what about firing up?

The reason they don't like Audiobahn is cause it really isn't that great anything. There are a good deal of speakers that get louder, but Audiobahn is a good one, just not the best.

if you want lound unclean music like haibane said by all means go with audiobahn, but when you get tired of that, look into adire or elemental designs. then you will get loud great sounding clean music.

look i'm done with this post, serinity now!!!!!!!!!!!!!!!!!!!!!!!!!!!

Audiobahn AWISD15 for $294.99 - Approval code: B07P4029 www.thezeb.com (http://www.thezeb.com)

I don't know about making one to fire up. How will it sound as compared to facing back? Also I think it would be very coplicated to do and especially to fit. So say I would do a 15 firing up which way should I face the ports?

you want the ports facing the same way as the cone, so up

Firing up just decreases the SPL by a tiny bit (with a ported 15 this shouldn't matter), and it's supposed to give a little more SQ than firing back.

While were on the subject, what does firing down do with 180 reversed polarity SQ SPL wise.

Well we can rule out one fifteen because I just bought 2 12's today for very cheap. They're the Audiobahn aw1251t, which is their base 12 400 RMS each 4 ohm dual VC. I went ahead and got theese because they were only 80 bucks for the pair and I wasn't passing up that deal. I'm still going to wire each to one amp but I will just have to turn the amps down a little bit since they're only 400 watts and the amps are 460. And bash me all you want but I also got new audiobahn components. 4 6.5's with seperate tweeters and 2 3.5 mids. The whole system was only 175 and retails probably 400-500 so I thought it was a great buy and if I'm not happy I can turn around and sell it at least for what I bought.

Retails, or is MSRP...

The full price for what the manufacturer sugests.

yeah, I can get most of that stuff for a bit less than what you said, oh well...

Yeah but even with shipping? Plus I bought it all at a mega sale thing though so it wasn't like getting stuff online where your not sure what your getting. Okay now for installing this badboy. I know how I'm going to do the subs but for the rest here was what I was thinking give any input as to how I could improve. I have the Mach 460 so I'm going to replace all the tweeters with the audiobahn ones since they're removable and keep the factory amp for those. The 6.5's I'm putting where all the 6x8's were. This is where it gets hard They're all amped from the mach 460 (ford built) amps. The 6x8's are Dual voice coils and the factory amps are : Ford Mid/Low-Pass Amp - 2x85w = 170w Max. 2x43.5w = 85w Nom. And there's two of those. I was just going to power the 6.5's with the reciever (pioneer 40Wx4) and use crossovers, but if it would be better I can use the fatory amps but how would I set this up? With the 3.5's I was going to cut holes and mount them in the back tray and use a power coustics component amp and a crossover for those they're 60 watts RMS for the pair and the amp is 30 watts RMSx2 so its perfect. Then for the subs I'm going to run one amp to one sub theyre 4 channel and will be bridged but I've went over this earlier in this thread, but I'll just need to turn them down a little bit since they're 460W and my subs are 400W. Okay so anymore questions on it ask and I need some input to make sure my setup will be okay. I've checked all my ohms are right except if I use the mach 460 sub amps for the 6.5's then I don't know about the ohms b/c I don't know what they are for the amps and especially since the factory speakers are DVC. Thanks in advance.

that is one long ass paragraph, maybe I'll read it tomorrow

Ah come on someone I need some input.

Yeah that is long...
