So here is how the (what should have been) simple driver replacement went. For those that weren't aware, I purchased two MFWs a few weeks back and one of the drivers was most likely damaged in shipping and knocked out of alignment. This caused the driver to hit/rub and generally sound like crap. I don't fault AV123 for this at all. They were very helpful and immediately sent out a new driver...even though it was most likely due to rough handling in shipping and not their fault. I continued to use my other good sub and ran the damaged sub at very low gains (no more than 1/4 turn) and limped along while I waited for the new driver.
New driver arrived today and I'm excited to finally hear what two healthy MFWs will sound like. Mr. Schifter was kind enough to ensure the leads were soldered in so that all I would have to do is plug and play. Sweet! I go to work on replacing the driver.
In short, my A stock sub must have been swapped with a B stock. I honestly didn't look this sub over too closely when I first got it because the crappy driver was my main focus and after it was confirmed it was bad, the sub just sat in a dark corner out of sight, out of mind. Looking closer now, it is pretty beat to hell. One of the screws (head) on the face place was stripped before I even touched it. With a larger allen I was finally able to get it out. Not a good start on the driver replacement. Start removing the screws holding the driver in place and two of those screws were stripped from trying to tighten the driver too much by the installer (or previous owner?). Pull the driver out and see that the driver had been screwed in at two different places, meaning double the screw holes. Those screw holes that weren't used were all uneven and raised up and the sealant tape that should have gone all the way around the driver only covered 3/4 at best. The hole that was cut for the driver is slightly too large which causes the screws on one side not to get enough "bite" and is (probably) why the screws were stripped and rotated and has all the extra holes. Speaking of holes, it doesn't seem that any of the holes for the screws were pre drilled as the back of all the holes was gouged out and breaking from the back. I filled all of the holes with putty and smoothed everything out so that when I put in the new driver it would at least be flush.
The leads running from the driver to the amp are simple plugs and were already soldered in place for me. Greatly appreciated and should have made the job much easier. Problem is the lead coming from the amp isn't long enough to come through the hole in the front! If the wires were 2" longer, people (I) wouldn't have to remove the amp that my as well be welded in place just to plug it in, not to mention the damage the amp does while popping out.
So the holes for the driver are sealed, the surround on the driver is sealed and I'm ready to feed the leads back to the amp and screw the driver down and put the faceplate back on. Get it all in and luckily the new sealed holes seem to get a good bite and I left it better than I found it. Move to the back, start removing the screws from the amp (hadn't pulled it off at that point yet) and realize those screws are all jacked up as well. None of them go straight down. Some angle left, some angle right, one is stripped from overtightening and another has a stripped head. Fight the last screw with the stripped head and finally get that off and then run here to figure out if anything else is needed to remove the dang thing (thanks again GreyBeard).
Ok good, everything is now plugged back in and all looks well, accept the amp won't go back in flush like it initially was and I'm not about to take a hammer to it, even a rubber mallet. It was sealed and I called it good. Turned the good sub off so I could just hear this one. Plug it in w/o the cheater at first just out of curiosity to see if the hum magically went away (interconnect not hooked up at this point). Surprisingly no hum, just an odd (loud) static sound. Played with the gain to see if static would go up/down and no change. Good..so I thought. Hooked up the interconnect (nothing else running) and still no hum. Good...so I thought. Turned on the AVR and still nothing from the sub accept for the static, adjusting gain does nothing. Hook the interconnect into the other sub that I know has been working and it fires right up. Go back to the bad sub with new driver and again nothing but static. Green light is on but nobody is home. AAAAAaaaaahhhh!
At least I have one good sub because if both were bad I would be livid. Mark and Kyle are amazingly nice people but this is really getting frustrating at this point. Should I just box the whole stinking sub back up with both drivers and ship it back to you guys?? I don't want this to seem like I'm bashing AV123, I'm not. Their customer service has been top notch. The one MFW that is working is great. This sub that has been problems from the start, and upon closer inspection is all beat up, is trying my patience however.
