Im a little confused about what the rms for the sub is, iv seen it listed at 500 watts but iv also seen it listed as low as 50 watts. With the peak being 1000 watts. So what size amp should i get and does it mater if the peak watage on the amp is higher then the speaker if the rms is not higher then the speakers rms?

peak is 1000 rms is 500, i have 15 compvr 15s for my subs and i run each one to a kicker kx 600.1 at 4ohms giving it about 300 watts, and its loud with both of them, id recommend the jbl 600.1, more power than the kx600.1 prolly and can handle 1 ohm load. i dunno why im going againts my religion(kicker) lol but i guess jbl is the way to go. as for the 50 watts, that prolly the rms 50-500 rms. good luck

Yep, JBL 600.1 is more than enough for a single Comp VR 15" sub. This sub is rated at 500 RMS while the 600.1 puts out more that 600 RMS at 1-2 ohms.
If you plan to use a pair of subs, can wire them to get 300 RMS per sub which is nothing to sneeze at. (series/parallel - 2 ohms load)

thanks for the help, I think im going to get that amp. I just have one more question though, my friend was telling me I should get a Rockford Fosgate Punch 500s and I went look at it and it was the same price as the JBL so I was wondering which amp is more powerfull.

The 600.1 is more powerful. you get 600watts RMS from the 600.1 and thats pretty accurate because its measured at 12.9 volts, or something close to that. The 500s will give you 500watts RMS, but thats at 14.4 volts, and most electrical systems dont put out that kind of power. So basically, the JBL amp will give you at least 100 more watts.

Yes, that is true as RF does rate their amps at 14.4 volts input, (which no vehicle can sustain for more than a few minutes after a cold start) and the 500S is also going to draw same or more power than the JBL as it is a Class A/B amp VS Class D on the JBL
Class D amps put out ~85% power of what they draw. Class A/B amps are a bit cleaner, but you get 55% power of what they draw... big difference.
So.. take your pick less power and more current draw with RF, or more power and less current draw from the JBL 600.1 (which is underrated at 12.9 volts).
