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...

you may only be able to get but so much out of the subs. If you turn the bass down a little so the that you dont drive the subs so hard you may get a little more wattage out of them

The JL 1000/1 will power the Orion HCCA OK.
It is stable only to 1.5 ohms so your best choice would be the 15.4 with dual 4ohm voice coils. In parallel, this would offer a 2ohm impedance. The 15.2 could only be wired for either a 1ohm load (too low) or a 4ohm load (less power).
Hope this helps.

Do you get sound if you set it on full? If you don't get sound in any way it maybe broked. Do you smell burnt components? Is the protection light on? If so you probably have a shorted transistor inside. If everything looks normal but has no sound at all. The preamp circuit is probably not getting power due to a malfuctioning power supply circuit. The way a car amp works is it has a DC-DC converter, which steps up the 12 volts to two supply voltage. One is usually a -35V, an the other is +35V. To a totall of 70V. Power transistors don't operate efficiently on 12 volts thats why it is designed like that. A PWM (pulse width modulation) circuit which consist of a chip, and various components connected to it drives an array of Power FET(field effect transsitors) usually conected in parallel to add power. These FET drive two or more "powder iron core" transformer. The other side of the transformer is connected to large diodes, providing power to the transsistors that actually drive your speakers. The supply voltage to the section preamp section is usually the same as the battery voltage. This preamp section filter high frequency for things such as low pass, high pass etc, and through many stage of amplification using small transistor, the final stage is the large transistors that drive the speakers. If you can tell me more info I can help you with a step by step guide on fixing the amp.

Re-check all the connections to the speakers, The uPC monitors all the outputs and if any are taking more power than they should, the uPC shuts the amp down to protect the internal components. Don`t use tape joints alone, try to run the cable the full length without any joints. If you do have to piece the wires together, solder them and stagger the connections, in other words, make one lead shorter than the other so that if the tape does come off, the offending connection is well away from the other so they can never meet or connect to each other.
