With your multimeter set to DC volts and the black meter lead on the ground terminal of the amp, touch the red lead alternately to the B+ and remote terminals as the amp shuts down. If the voltage drops below ~11 volts, you need to check the wiring feeding whichever line is dropping too low.

If the voltage is not dropping too low, you may have a defective speaker or a short in the wiring. Check the resistance of each individual voice coil to make sure all are near the rated impedance.

Can i use my jensen 340 mono amp with a 500 watt 15'' subwoofer

You can, but I wouldn't advise it. Won't sound that great, your probably going to overheat your amp. It may go into protect mode. You need a bigger amp.

How many svc subs at 4ohm does it take to get this amp to 1ohm stable and can you reccomend a good sub combo for this amp whether it be dvc or svc

It depends if your sub is 4ohm svc, or 2ohm svc. 4ohm would take 4 subs wired in parallel, 2ohm would take 2 subs wired in parallel. But for a amp that big, subs that'll handle it are definitely gonna be dvc. I'd recommend 2 Orion 4ohm dvc hcca's. They come in either 15in or 12in. the 15s are louder if you have the space for them. As far as wiring goes, wire the voice coils on the subs in parallel to 2ohm per sub, then wire the 2 subs in parallel to 1ohm. Goodluck and congrats on the equipment, Orion is about as good as you can go for subs and amps. just be ready to lay down some dynamat cuz this system'll bloww your vehicle apart! good luck...

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.
