    Ok apparently I am not good with the wording of my problem. My amp is blown and I have it at my expert now. Unfortunatly he cannot read the "chips" on the ends to replace them. So since I do not know their names I will describe them. They look like little black chips and they have 3 leads on them that are attached to the bored and a screw hole on the opposite side. Now I am told there should be a diagram explainin what all the chips are but ALL I really need to know is what they are so we can order them. My fingers are crossed that someone out there knows. Thanks for your time in readin this and tryin to help

    Most of the 3 legged components clamped to the heatsink are power transistors. If I'm not mistaken, they used 2N6488s in the power supply. He should be able to make out the numbers on enough of them to determine if that's the correct part. They also used transistors with E2889 stamped on them. They are essentially the same as the 2N6488.

    If he has questions, tell him to email me.

    Orion never released service literature to the public. What's wrong with the amp?

Schematic for orion HCCA-D2400

The schematic or service manual doesn't appear to be available online. You may have to contact Orion. Verify the REM input to the amp. It should be 12V when the car is on and 0V when the car is off.

Wiring diagram

Hello rivertoyz,

If your F250 has the stock radio, there are no preamp outputs, so you will need to use the speaker outputs. The best solution would be to wire a LOC (line output converter) to the rear channels and run RCA cables to the amp.

Speaker wire color code:

Left rear positive - Gray/Light Blue
Left rear negative - Tan/Yellow
Right rear positive - Orange/Red
Right rear negative - Brown/Pink

You'll need an amp wiring kit with 4gauge power and ground. Both the LOC and wiring kits are available at numerous online stores. The best service is from Another reputable online seller is

You did not say what subwoofer(s) you intend to use with the amp. If you want to stick with the Maxxsonics product, a pair of 10" Orion HP10D2's would be an excellent match. Wire each of the subs dual voice coils in series for 4ohms, then parallel them to the amp for a final load of 2ohms. Both of the linked retailers above sell the Orion's and many other brands as well. Just make sure that your sub selection has adequate power handling capability. At least 1000 watts RMS if you use a single sub and 500 watts RMS if you go with 2.

Hope this helps.

Can and how to crossover

do you have a copy of the install manual? if not i have the url for you. you didn't say how were going to use the 250sx, but i assume you're planning on using it as a sub driver. an active crossover would be best in this application. orion has them & there others available as well. try to avoid passive crossovers because they absorb some the output power. there is an equalization switch that you use to further balance the system. the bridged mono mode produces about 400W which is pretty decent.

you didn't mention the power rating or impedence of the speakers. those specs determine where we go from here. checkout the manual, get those speaker specs & get back to me.
