This is for those of you that purchased the HR upgrade kit from av123 that used the new amplifier (500watt) and the aluminum driver from AE.

When your amplifier dies, I now have a fix. I hate to say this but from what I have seen so far its just a matter of when not if, as I have seen/heard over 10% of these fail so far. 

This will give you the response that Mark wanted when he was working on this before av123 took over the project.  It will also have good overload characteristics.

If you still have the original 1000Watt amp you can send it to me and I will rework it for the AE driver.

If you do not have the original amp, I can get a new retail version of the amp and modify it.  This will carry a 1yr warranty from me, although I cant say I have heard of any of these amps failing since 2005 when they were put into service.

If you supply the amp it will be $200+ shipping
If I supply a new amp it will be $495+ shipping

I have an HR ufw-12.  I don't have the original amp, but I do have the original driver.  It is making a high pitched squeal that has rendered it useless.

I don't have the money for a totally new amp.  Is there anything I can do to fix the HR amp?

My UFW12 HR failed but I have the old 1000 Watt amp, I was using a MFW15 but it just failed also. So I’m sub less at the moment.

I have the original 1K UFW12

I have two V2 amps for MFW15.

The first amp had some scratching. Sean sent me a new amp and that solved that. So I need to see if the first amp still works so I can get both on line.

As with everyone else money is driving my decisions.

Can I send in the original amp to get reworked? if my other amp for the MFW15 works can I get that reworked?

 

Thanks in Avance

So chalk me up to one who didn't realize my UFW-12 HR amp was going bad. It was popping and screeching intermittently for the last few months and today just starting to screech loudly. I had to unplug it to make it stop making sounds.

So amp is I guess fried?   I didn't keep my original amp or woofer. So to be clear this upgrade uses the HR woofer and a new amp?  $495?
Can you do anything with the existing amp or is it now trash?

At this price am I better off getting a "new" used small block UFW-12? Or is this going to sound better since it's the Hot Rodded woofer?

Also I'm debating if I should take this opportunity to upgrade to a new sub. Thinking the SVS SB-13 plus?  or 13 ultra?

How would this compare to either of those 2?

thanks!!

I was in a similar position, I installed the HR kit, and gave away the original amp, then the HR amp began to go bad. I installed the new amp for $495, have been using it for a couple of months without any issue. I have good response to below 20 Hz, and the new amp is working w/o issue. IMO, for $495, it is the lowest cost route to having a very good sealed 12" sub. If you still have the original UFW-12 amp, you can have it modded for less $$, and obtain similar results.

Here is a link to my post after installing the upgrade, 4 months later I have no regrets.
