I am by no means great at wiring things, but I've gotten a little ambitious. In fact, a little too much, which is why I'm here 2 Amps, 1 Sub Wiring -- posted image.
I have an Audiobahn AW1200N sub, which is 350W RMS/coil (its DVC) for a total listed max of 1400W. I got it from my buddy who decided to use his Jeep for off-roading and wanted to get rid of his subs, so I only paid $30 for a sub that had barely even been broken in, not bad. Being that I didn't have an amp at all, my dad (who's electronically retarded just like me) got me 2 amps, both Audiobahn A4002Ts. They're 2ch. 400W RMS amps for a peak of 800W (I believe at 2 ohms). My dad got them off eBay NIB (new in box) but they're over the return policy limit of days, so I can't return them and would like to wire up my system. What's the best way to do this?
(I searched, read the 5 page flame war on how to wire 2 dif. amps to one sub, didn't really get anything out of it... so if this has been covered somewhere else sorry)
Being that I'm electrically retarded, I have a picture that anybody can edit in MSPaint lol

Pretend that the woofer isn't one woofer with two coils, but two individual woofers with one coil each. Wire one amplifier to each voice coil, and set the gains. Easy peasy.
It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

pay close attention to the settings on the amp.  You want your gains and filters set as close as possible.  I would only do this w/o setting the gains with a dmm.

Another thing - I think the 700w rms rating on that sub is a little optimistic, so I would suggest setting the gains on the conservative side.

If you're careful and take your time  it should work out pretty well.

You'll probably need to pick up a 4 ga amp kit - one with a power distribution block might be a good idea.

I did pick up 4 gauge wire, so I'm one for one so far. After doing a lot of reading around the forums here, I've learned to make sure the gains on the amps are close if not exactly the same. Two for two. Power distribution block? Two for three, I have a good idea of what its for (duh) but um... like I said, electrically retarded. I don't actually know how I've gotta wire this. The power cable has already been run, as are the RCAs... but the actual sub+amp setup... pretty shaky.
Oh, yeah, the picture apparently doesn't work...

.jpg works.  .JPG doesn't work.  And less than 30 KB is necessary.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

hrm... I tried uploading one and it was 26k... that was the second time around. The first time it was linked from my photobucket account...
let's try ascii....

I'm unsure of how the connection ports are on the sub, meaning I don't know which ones are positive and negative, they're not labeled. So... how does one wire this beast?

Sorry, you can NOT post a reply.
