My light comes on at extended listening levels. Is this normal? It dosent stay lit solid but acts more like a peak or threshold light. Dont know much about the light at this end. I understand loads and impedience but not the silly light

Re: hey quick question on JL 300/4V2 impedience light
If you're referring to the orange "Low ohm" light, it's most likely caused by the amp detecting a "lower than optimum" impedance for it's gain setting. The quick answer is you'll probably have to go through the steps outlined in Appendix A of the owner's manual. This will set the amp gain and input voltage setting properly for your speaker and head unit setup.

you have your sub wired incorrectly. your amp shouldn't get hot unless you're settings are too high or your'e sending too small of an ohm load to the amp. this would cause it to heat up and will fry your amp.
i highly recomend you use the hifonics colossous and wire the subs @ 2 ohms and you would be right about nominal power handling for the W7 which is rated @ 1000W, and your amp would push about 1100W to it. just be carefull when adjusting. and the best advice i can give you on the settings is as follows: Turn up the volume to the desired listening average level. (what you would normally have it on when driving) then adjust your amp by turning the different controls up, and then back down a 1/4 turn after distortion occurs. in your case with so much power dont turn them up all the way right away ease into it be gradual listen to the change in the sound.
Running the amplifier at a low level shouldn't cause it to get hot quickly.
Disconnect all speakers and signal cables from the amp and power it up. Do this when the heatsink (black part at the back of the amp) is cool. Power it up and monitor the temperature of the sink. If it gets hot in one relatively small area, that will tell you that there is likely a problem with one channel. If it never gets hot, the problem may be with the input signal or the speaker wiring.
Disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up, the wiring needs to be checked. If the protect light remains on, the amp likely has blown output transistors.
hi, have you figured out whats wrong with ur amp ...i have the same amp ....and as soon as i finished the connections ...and connect the remote on wire,,, the amp goes on ...making a ticking sound with the green light blinking and the red light staying solid on ...whats the problem please help ....how can i fix this ......my amp is a jl e6450 ....im using a panasonic cd player with a built in amp ....and thats the cd player im trying to connect to the jl amp ...please HELP
I do belive this amplifer has a red light when it is on... I know my Kenwood does.
I suggest checking all your wireing between your amp and your speakers, check the impediance between your positive and negative terminals on your leads to the subs.
