So I get my amp from FiLLuP Tuesday and I have my friends 3x10 bandpass box in my car already. Tuesday evening I go home and set out to hook everything up. I spend 3 hours in the cold running all the wiring (consequently fvcking up my left rear somehow that I have not determined) to the back of the car.

I re-wire the subs in the box with a larger gauge speaker wire and mount the amp on the top of the box.


NOTHING.... damnit! Just a red led on the amp when it turns on.

Last night I start checking each of the coils and discover that one coil on each of the drivers is bad, so I rewire the 3 remaining coils and hook everything up. Still nothing. I disconnect my head unit and plug my iPod directly into the amp and still nothing.

I eventually discover that, as my fears had predicted, UPS had beat the hell out of the box and there is a small short in the positive power lead on the amp. I can nudge the block just right so that the amp fully powers on and I get sound!

So I have it rigged with a little tension on the block to maintain power and head out to test it.

WOW, apparently this Xtant amp can really handle a beating because at this point I am running a 1.33 ohm load in bridged mono (the amp is rated at 400x1 into 4... I am at the point here where I literally said screw it, if I blow something, at least I will have a short time of enjoyment.

I get about two miles away and I'm listening to Infected Mushroom - I'm the Supervisor, and a particularly deep, rapid, intense succession of bass beats hits, I feel as though I am about to shake apart (totally impressed that this is coming from 3 10 inch generic subs) and then nothing.... the power connection had vibrated enough that it failed.

Now, for some reason the drivers are not making hardly any sound when I get a good power connection. I think I blew the other coils! hah! My friend will probably be a bit upset with me about that one

Tonight I am going to open the box again and test with just one coil connected and see if I get anything. I am also thinking about re-soldering the power connection to take care of that problem.

You may have damaged the amp I'm not sure of the specs but I think it's only 2ohm stable.

yeah, I pretty much wouldn't be surprised if that is the case. Though on the way home tonight it was working again. I will re-solder the power block and see what happens there, I am also thinking about just wiring the subs up with two parallel and one in series to the other two to get it to a 4 ohm load.

Ultimately I may end up giving the amp to my friend and let him screw with it Pick up a couple MTX 10s and amp once I have a bit of free cash.

This three drivers thing is a real pain in the ass
