Is 500w rms for L7's enough?

Question

I have 2 solobaric 12" L7's which can handle 750 rms each, my amp is 2000w by one at 2ohm but I have 4 ohm dvc subs so I can only wire to 4ohm which would give me 500w to each sub. Is this enough power?

Answer 1

yes

Answer 2

When there is not a clipped signal, no one has ever blown a speaker due to sending it under its RMS.  That is a horrible misconception and a ridiculous myth to keep going.  500 watts is plenty of power for the L7's, and you will actually be doing your amplifier a favor.  But running the amplifier at 4ohm mono instead of 2 ohm mono, you are putting less strain on it and could very well extend the life of the amplifier, not to mention less current draw on the electrical system.

If you are not happy with the output with the sub woofers wired at 4 ohm mono, look into tweaking or rebuilding your box.  It is always cheaper to rebuild then buy new equipment.

Answer 3

you should be able to wire the subs to 2 ohms if the amp is a 1 channel that would give you 1000w to each sub or if  its a 2 channel bridge it to the amp and that gives you 2ohms

Answer 4

i would say NO, i would send more wattage than that to a L5

If you send too much power to your sub, you risk damaging it. The cone of the speaker and the mechanical parts that make it move may break under the stress. Surprisingly, too little power can also damage your subwoofer — in fact, it's actually more common than damage caused by overpowering.

When the volume is turned up and the amp doesn't have enough power, the signal becomes distorted, or "clipped." This distorted signal can cause parts of the speaker to overheat, warp and melt. Not good!

You don't have to match speaker and amp wattages exactly. An amp with a higher output than the speaker's rating won't necessarily damage the speaker — just turn the amp down a bit if you hear distortion from the sub and don't run the speaker at extremely loud volumes for lengthy periods. Likewise, you'll be OK with a lower powered amp if you keep the volume down and don't feed a distorted signal to the sub.

if you have 4ohm DVC subs they can be wired to give you impedances of 1 or 4ohms at the amp depending on how they are wired--- here is a diagram to help you http://www.the12volt.com/caraudio/woofer...

so depending on your amp (if its stable below 2ohms) you can wire it down to a 1ohm load at the amp (i hope your amp is CEA-compliant or you will just damage your subs)
