First thing is to make sure that the 15" subwoofer's RMS power rating (not peak power rating) is at least 250watts. Also, you have to be sure that the woofer is in the right enclosure. I am guessing that since you didn't post a model number for the subwoofer or the type of box it is in (i.e. - ported or sealed) that you are putting the woofers in too small of a box or too big of a box. Trucks typically don't have much room for woofer enclosures, so many people favor smaller boxes. The incorrect box will affect how the speaker cone moves due to the internal pressure in the box. Too much movement without and the voice coil hits the magnet causing that "popping" sound. reducing the gains on the 250/1 can often help.

I have a Jl Audio 250/1 mono block amp and the thermal light keeps coming on what could be causing this?


It could be a number of things? 1 to many subs, speakers wired to the amp causing it to overheat and making the thermal light come on. 2 It all depends were your amp is. If it's clear and nothing covering it, obstructing it, Ie sub in front of it, amp inbetween the rear seats and sub.

Shuts off when the volume gets turned up didnt do this wen new


A mono amp usually can handle only two 4 ohm subs. You see when you hook up two subs in parallel it drops the ohms too 2 ohms and 3 in parellal drops it to 1 ohms overheating the amp and cause power failure. Unless you bought a Mono amp thats 1ohm stable. But still I've seen cheap 1 ohm stable amps not last long. Also possible your subs are fried too check them with a multimeter and measure each sub ohms.

I hooked up my two 10 inch JL Audio W3v2 2 ohms to a mono JL Audio 500.1 amp and the subs will not work. I have the subs wired in a series. I then hooked them up to my friends amp and the subs worked. Any...


try one at a time. if they work then try hooking them up differently. if none work, then check to see that your amp is not in protect mode. if amp is ok, then check to make sure you have your rcas connected to your amp. in other words, re-check all your wiring. if still nothing, try your amp on your friends car and vise versa.

1 10 jl jl 250/1 mono block amp cuts off an on help


your subwoofer is wired incorrectly to your amplifier. Figure out which ohm load of subs you have and then what ohm load options your amp is stable at. Next go to either the Crutchfield website. find their learning center. go to subwoofer wiring diagrams. or go to www.the12volt.com and find their section on it

My JL subs just dont beat like the ONES IVE HAD before as well as the ones my friends have had


sounds like they have your sub amp in mono but they put the speakers in series which totally cancels the benefit of running your amp in mono. you will probably be happier if you just hook the left speaker to left plus and minus and the right to right plus and minus. Cuz even though subs aren't directional they do pass some higher frequencies that are and that dilutes the stereo effect.
