most of the time when a high power amplifier starts making noise not all the time but every once in a while or even all the time its the ground, if the amp turns on its not the power cable. try moving your ground to a different location or try using double grounds. the better the ground the better the sound. and as for turn on pops, put a toggle switch inline on your rem wire and turn it on after the car is started.

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.

Depending on how much you paid for the amp on eBay, and how well you like the JL product, it may very well be worth the money to get it fixed. As for the wallet damage, you'll have to ask JL or one of their dealers. But, since the Slash2's routinely sell for over $1,000, I'd estimate the cost to be pretty high.
First, I'd send an email to JL Audio tech support and see if they have a "flat-rate" repair option or if they can give you an estimate of the repair costs. My second option would be to talk to a local car audio shop that does component level repairs. In the first case, you'd get exact replacement parts and whatever warranty JL gives on repairs. Not so with the local option, but it would most likely be less expensive.
Hope this helps, good luck.

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.
