I've never heard of "lucky Star" amplifiers in over 20 years of car audio. The Pioneer amp's rating of 500 rms is probably the gm-d510m, in which case, an excellent amp for the money. The "rms" rating is the one you want, as that tells you the amp's average rated (real) power output. The peak number as in the "Lucky Star" brand is meaningless for the most part, as those ratings are far from accurate, and no one knows any of the measuring parameters. The peak rating could be for a milli-second (or less), and using 15 volts (or more), and the actual amp tested may have exploded just after delivering the peak output. Stick with good, brand name products.
