Seeking Advice

Daveds50, and anyone else who cares to chime in,

I bought my A3-300 back in Apr 2008. This must have been one of the original ones with the downfiring driver which I upgraded to the 13Ov2 Dual coil, and this one came with an LT 350 amp. The label "LT 350" is a sticker that is covering the original label what ever it is.

Anyway the sub is actually still working but I'm interested in avoiding the failure modes that plague this subwoofer.

It looks like my best bet is to replace the driver with the Infinity 1260W before the coils on my driver short and take out the amp. There is no indication this is happening, but I don't tax the sub like I used to.

I'm wondering if I should also have the caps replaced on the amp? Daveds50, do you still do this maintenance on this amp? Is it worth it to replace these before they fail and do more damage? I don't care to mod the box to replace it with a different amp. I'm looking for an affordable way to keep this sub going for several more years.

Thanks...

Here is a link to my post back in 2008 when I got the sub.....

you may have been lucky and got one of the better drivers from that time. they were not like the later models that had a high failure rate. however, it is pretty aged... and drivers do not last forever. all depends on how hard on it you were for all those years.

but... know that the Infinity is much more efficient. it will be much louder on the same power.

as far as the amp goes, do a visual check on the capacitors. if any are bulging the tops, ( including the tiny ones under the heat sink ) then it may be time for a rebuild. if you wait too long, then major damage can happen, and know that a lot of the parts are no longer available for that amp.

you dont want to replace that amp for a different reason than you think... the amps at Parts Express are a downgrade from what you have... i fix those amps too.

Thanks Dave for the quick reply. I removed the amp and took some pics. The smaller caps under the heat sink don't seem to show any signs of bulging. The large caps don't look bulged but I'm not sure about the discoloration at the base of the caps. Is this flux or are these leaking?

The driver was only used on Sundays to listen to church music. But seriously, I didn't drive it too hard but I think I'm going to go ahead and order the 1260W and replace it anyway. I assume there is not much salvage value to the old one.
