Wayne is right. Unless you have a particularly muscular source to drive the interconnect, a long interconnect would degrade the signal to the amp.Whether the long speaker cables are a problem for your amp depends on two things.
First, some amps cannot tolerate much capacitance in parallel with the load. It affects their feedback loop and makes them unstable. Long speaker cables with a lot of capacitance per unit length might be enough to push some amps over the limit.
Second, speaker cables can pick up RF noise, and some amps are sensitive to RF noise on their outputs.
If you want to find out cheaply if your cables are a problem, place some R-C networks across the amp and speaker terminals. Use about 10 ohms for resistance and about 0.01 microfarads for capacitance. Expensive components are not necessary to see if you have a problem. Wire the resistor in series with the capacitor, and place them with the capacitor on the (+) terminal and the resistor on the (-) terminal. Listen for improved midrange, smoother treble, and an overall sense of relaxation along with clarity.
If you hear an improvement, you can make better networks from old-style Holco or PRP resistors and silver-mica caps, and solder them to the ends of your speaker cables.
If nothing changes, then you don't have these particular equipment sensitivities and can stop worrying about your setup.
