I had to get a new plate amp. However I have to retrofit the driver into the box. In the mean time I was contemplating just leaving the plate amp by my listening area and running a speaker wire to the speaker in the sub box.
Is there any problem with that? Being I'm running a long RCA cable to the amp, what's the diff here?

I remain somewhat skeptical about the degrees of difference these kinds of decisions make. Maybe my hearing is too insensitive to hear the tremendous differences claimed for speaker cables and interconnects.
Anyway, my suggestion is that you could just try some of the 12 gauge outdoor stranded copper wire sold by The Home Depot for ca. $0.75/foot to see what that sounds like. May surprise you.
Good luck,

Hey, I'm a BIG fan of cheap cable. I believe there is a difference with cables and wires. But not to a manic degree.
As of late I've also enjoyed finding out how much resistors and volume controls can effect your system. That really was an eye opener.

If you're already using a "long" RCA cable, why does the speaker wire need to be long as well?
And why has a new plate amp resulted in the need for a driver retrofit?
Your post is confusing to say the least.
In any case, I'd rather run a shielded signal cable a few extra feet than using 12 or 14 ga. speaker wire for a sub. Plate amps often don't have high damping factor - so you don't want to lower it more with long cable runs that are too small in size.
I'd do the retrofit(s) and with the shorted wire 12ga would probably be adequate. For 10 feet you'd want something bigger...
Cheers,

No no, I'm running a long RCA cable now. But if I use the speaker wire I can move the plate amp nearer to my stereo equipment, ie 2 foot rca cable to the amp and 15" wire run to the woofer.
I was using a Paradigm subwoofer, until the amp blew out. Paradigm used a smallish (cheap) plate amp. The Keiger that is replacing it is about 30% larger.
It would save some time and aggravation retrofitting it by cutting the box.
And I could play with the setting right while sitting right next to my stereos listening area.

The longer length of the RCA cable will have negligible effect, unless it's a very poor cable and you've got any noise issues. However, running long speaker wires from a plate amp to a sub is not a good idea and *can* result in performance issues (damping factor).
I would retrofit properly, then run the RCA cable from the system to the sub and make that cable as long as it needs to be. (Once a sub is set up there is no advantage to having the plate close to your listening position.)
That's my 2 cents anyways.

I think he means not putting the amp in the speaker enclosure. It should work fine. The sub amp should have plenty of damping factor (higher than any tube amp, anyway). I have done this before (locating a plate amp with the rest of the equipment), and run speaker wires to the sub. Worked fine. I find that longer speaker wires is better than long interconnects, where capacitance can cause HF rolloff, or even oscillations from too much capacitance. The high signal levels on the amp output is much less susceptible to noise pickup.
I have the sub where I like it. And I have enough good quality RCA cable to run too the sub.
The only reason I wanted to try the plate amp by my stereo was so I can fine tune the settings at will. With out a zillion "get ups and downs".
Thanks

...said the blind man, as he picked up the hammer and saw.
Yes I run plate amps out of the box often - in fact more often than not. But I am very close. If it's 8 - 10 feet or more I would use heavy cable... 10 or even 8 gauge. That's just me. You could get away with 12 gauge. It may not be a deal breaker for you performance wise, but it will affect damping factor.
Cheers,
Presto
for subs as well.
It conducts a low impedance signal (as opposed to a high impedance line level signal via interconnect) that is subject to losses via resistance. You may already have some 12-14 gauge speaker wire lying around that should do the trick.
