Ok, I bought a couple Audiobahn 12" 1206Qs a little while ago, and I want to get them installed soon but I got a little problem, no amp. I don't really know anything about audio stuff, but I know that both subs handle around 1200 watts.

Since I am using 2 subs, would I need a 2 channel amp? And if the amp is rated at 1200 watts would it be split to 600 watts each for the subs? I just want the amp for the subs, the speakers are alright.

Thanks

The amp rating of 1200w is the MAX power rating and so therefore you amp can max out 600w per channel if you get a 2 channel amp, or 1200w MAX bridged. With a 2 channel amp, you can either run the subs bridged or in stereo. A mono or one channel amp is meant only for subs, and the subs have to be wired in parallel and then wired to the channel on the mono amp. I know it sounds confusing, but the easiest way is just to get a 2 channel amp, positive and negative from one sub to one channel, and the positive and negative from the other sub to the second chanel and switch the amp into stereo mode.

Haha alright, I actually understand it more now. So if I do the 2 channel set up and have it in stereo mode the subs won't pound at the same time, they will do whatever the left or right channel are doing?

What about ohms? I've noticed that once the ohms go up, the watts go down, like a 2 ohm 2 X 600 opposed to 4 ohm 2 X 300 or something like that.

How many ohms are you subs? single or dual voice coil? I prefer to have a single channel amp because it is easier to hook up... and they usually put out mroe wats for less money because they are only one channel, and they are made for subs... The hardest part is wiring the subs. And that really not even that hard, with all the knowledge here it should be easy. And how much money were you going to spend on the amp? You have to have a descent one for your subs to sound good, but even more important is the box you put the subs in.. have one? Answer thse questions and we'll be able to help you out alot more.

These are the specs:

Key Features:
120oz Double Stacked Strontium Magnets
Power Handling: 1100 watts R.M.S.
Frequency Response: 20Hz - 500Hz
Efficiency: 90dB
PHAT 2" Multi-layer Foam Surround
Stamped and Balanced Aluminum Cone
2.5" 4-Layer AVS Voice Coil
Dual 4 Ohm Voice Coils
2, 4 or 8 Ohm Operation
Mounting Dimensions: Depth; 6 3/4" Hole; 10 7/8" Diameter; 12 1/2"
Multi-connect Lug Lock Terminals

I'm not sure what half of it means, but whatever. I am not installing them myself, I'm getting a custom box made by a reputable shop in a local town, they are doing the wiring and all that buisness too. They just want me to tell them how they want it wired up.

Well like GunnaGetOne said, the easiest hook up is a mono or one channel amp that is made for subs, but the hard part is wiring your subs. Your subs have a wide variety of wiring options which is good, and with a mono amp you will get more watts outputted to your subs, but with a two channel amp you have even more wiring options. You can either wire them in stereo or bridge the amp and run it one one channel (like a mono amp) so you can do both. I like the 2 channel because it gives you more flexibility...stereo mode for driving around, bridged (mono) mode for competing.

With dual 4 ohm subs I would get the 2-channel. Simply because, in most cases, after the subs are wired together for a mono amp, your gunna have 4 ohms.( i don't think theres a way to get 2 ohms w/ 2 dual 4 ohms subs) Most Mono amps are made for 2 ohms. which means your not gunna get nearly as much out of the amp as you should. After you wire each sub seperately for each channel on a 2-channel, if you wire it right, you have 2 ohm each. ( or 8 ohms... but you don't really want that) most 2-channel amps are able to do 2 ohms per channel very easily. And then, if you ever get curious you can bridge the amp (basically make it 1 channel) and see if you like it better that way. i had a 2-channel phoenix gold amp and I liked how it sounded much better bridged. Keep in mind that alot of 2-channel amps can't handle 2 ohms bridged, which is OK becuase you'd have 4 ohms if you wired your subs together. If you want some sort of wiring diagrams lemmie know it not that hard.

you are going to have a problem though... 1100 RMS... i think thats what it said. That means you need at least 2000 watts (Recommended). amps that put out 1000x2 are very few, and very expensive. If I were you, because those subs need so much power, buy 2 mono amps that put out that much power. It will probably be cheaper in the long run because there are alot of amps that put out 1000 QUALITY watts. Now you can do less than that... like a 500x2 amp. I don't knwo how good those subs will perform with it though because they are made to have so much more power.
