Jensen Amp and Sub

It's possible the output stage(s) of the amp are blown. Check all audio wiring connections to the amp, input and output, to make sure nothing is loose or disconnected. Also, try wiring up a different sub to verify it isn't the sub that's bad.

ok if u have a radio with sub controll make sure its on an make sure that you have the gain bassboost turned up an if it has a crossover switch make that its on

If the sub is new, they need to be broken in.

All sub woofers need a break in period of about 5 to 6 hours at medium volume.
The reason is because the glue needs to be cured. This is done by the heat from working.

If you are giving it too much volume too soon, you are burning the glue.

Back off the subs and only play them at medium volume for about a week.

you should move up to more power....underpowering subs is bad! try not to go under the subs rms by 5o watts?

the amp is no where near strong enough that sound you hear is called hard clipping and it will destroy your subs in minutes. depending on what model JL subs you have I can sell you a better amp.

Just had a look at both amp and sub on the JL Audio website. The amp runs from 1.5-4ohms. 4ohms at 14.5V. The sub is running dual 4 ohms coils. That's what the D-4 means. So should be an easy set up. The amp has two mono outputs, so one for each coil. It looks like the perfect wattage to run the sub real nice.

if its cutting off and right back on then check your ground and your power wire makes sure both are connected good and none of your fuse's are blown, either that or you got a wire hooked up backwards in the sub.. but my guess is that the sub is hooked up wrong... that sub should be hooked up in a series or in parallel,

ok if your running just one speaker, it should be hooked up like this and 2 speakers are a different way...

this is parallel :pos to pos , neg to neg, then one wire coming from pos on sub to pos on amp then neg on sub to neg on amp but bridge the amp on your amp should be 2 pos and 2 neg in two different channels take the pos off the sub into the pos on 1 channel and then the neg from sub to the neg on the other channel,

this is series : on the sub it will go pos to neg then the other neg and pos will go to the amp, but make sure the pos and neg r on different sides of the sub, dont hook them both to the same coil

if your need more help give me your email and ill send you a pic of how to do it...

Ill go for a better GROUND , sounds like its not grounded properly and thats why the RED LIGHT . DO A RE CHECK on the installation . hope this helps

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

500watts sounds about right to me,i wouldnt go any higher as you risk popping the sub and haveing a melt down in the coil section of the subwoofer.
