JL Subs

[jharijan 10+ year member]

I got two jl 12w3 subs and had a quick question about them. it says they can handle 500 watts but on the spec sheet it says that the optimum power input for them is only 300 and 500 is in the danger zone. The reason I'm asking is because I'm thnking about getting a new amp and want to make sure I don't kill my subs by getting one that is to big.

just be careful with the gain and you won't blow shit

I've put well over 750 each to 12w3v1s and they sounded great.. as dragnix said, be easy on the gains, don't clip, and you'll be fine.

JL 500.1 slash2 or Arc Audio ks 500.1 is good.

so if I got a 1000 watt amp and set my gains with a dmm then i should be ok?

^^^^why 1000???

unless you plan to up grade subs??

500-700 mono block should be good.

What amp are you useing right now???

What type of box are they in??

& are they v2 or v3's ???

1000watt amp gives him the option to upgrade in the future

you won't hear the difference going from 600 to 1000watts.

he might need to look into better sounding subs.

The amount of juice a sub can handle is based on three basic points:

1. The heat it can remove from the voice coil over an extended period of time. This tends to be the RMS rating.

2. The peak wattage it can take without frying instantly. This tends to be the peak W rating.

3. The excursion, at a given frequency, before it becomes unstable and damages various parts. This tends to be what blows subs.

Chances are the "danger" rating they're stating is the rms limit, combined with the excursion limit. It's a guess at best. You might be able to push a 2500 watt peak, into the woofer at 100hz, for a brief second and not blow it, but 150 watts rms for 20 seconds, at 10 hz in a ported box, might tear it to pieces.
