Question about Orion 1200D Car Audio Amplifier

Playing music for about 2hours and bass amp shuts down

I'm running 3 amps two of which runs my Mids and Heights thats 4 6" ,2 10", 4 bullet tweeters and 2 high compression drivers. The problem I'm recently having is with my Bass amp which is a 3500watts class D monoblock, that runs my two 12" 1700watts Audiopipe subs. the subs are 4 oms Double coil each speaker is bridged + to + and - to - then one + and one - comes to the terminal. Then both terminals are joined + to + then - to - then one + and one _ goes to the amp. I'm running 4 guage from my engine to a 5 frad capacitor. the bass amp and one of the 4 mids amp is mounted on my back seat and the next mids amp is mounted on the sub box. When I'm playing my 4doors are open and the seats are down the trunk is poped so there is ample cooling for the amps. there is nothing wrong with the other two amps only the bass amp trips off. If I turn off the Bass for a couple of mins It comes back on like normal. Did I connect some thing wrong? Cant seem to figure this out, some people telling me this is normal but it dosen't feel normal to me. Any help I can get would be greatly welcomed ......................Andy .......Trinidad and Tobago

You have maxed out the amp! if your running one 4ga. pwr wire to all your amps, it's choking. Going to Wendy's buying a frosty and sucking it thru a straw!. Your amp is starving for more Voltage and current. That amps peak output is 1200w @ 1ohm, not too shabby! Now onto the next issue: Grounding!, just as important as power! Your amp MUST be grounded properly. Don't ground it to a seatbolt or side wall of the vehicle, go directly to the floor, hopefully less than 2-3ft tops. using the same gauge wire as power. If your power is longer than 12 feet, and in most cars it is, you loose alot of voltage and current flow to the amp the longer the run, the more you loose. That's just how DC power works. What's happening to your amp is it's working itself to death and creating massive amounts of heat. "enough to cook dinner" Run a 2ga or 1ot power wire to a distribution block at the amps. Wire in your other amps, then use the stiffening cap just for the sub amp. Not a cheap answer but it will solve most of your problem. Next, set the gain on the Sub amp NO HIGHER than 1 o'clock. Beyond this, and there's no help for it, there's no more gas pedal to push!. Enjoy your system but don't kill it! Hope this helps

It's been my experience,that intense and low bass comes with a price,always remember u get what u pay for,so on that note,Try to get Rockford Fosgate Competition subs with a punch 250 or 500 trust me that it is a powerful combination.and if u can afford it get a choke to put on ur subs so they will only kick bass put tweeters in the dash and mid range speakers in the door u could use a dual rca jacks to install 2 amps at once and get a punch 45 amp for the tweeters and mids.hope this was helpful

some amps are made more for low ohm loads (bass) and some are made for high impedence loads (mids/highs) and it seems you are asking too much from your amp.

The amps frequency setting is on LP (low pass) only playing bass so you have to put it on FR( Full Range) all frequency's and you'll get your sound back.

How can i test my rca output jacks with a test light? pioneer deh p3100ub. hooked up spkr, nothing. tried one rca plug to white(lt) and then red(rt). Unit has 4 rca jacks, 2 for subwfr and 2 for front...


:) the rca jacks have to be connected to an amplifier,, their signal is too lay to even light a bulb.. you have to connect it to a car amplifier and then from the amplifier to the speakers..

Just so you'd know,, once your deck plays and you hear music on your speakers through your normal speaker wires,, RCA jacks work..

Ok you have 4 jacks,, 2 subs and 2 front.. These should connect to a preamp,, which takes 4 inputs and allows you to equalize or adjust how the music should sound,, now from the pre-amp,, it runs to an amplifier,, thats powers the subs and another that powers the speakers.. Some amps have 4 inputs so you can use one amp for your subs mids and heights..

for example a basic music system is

1 cd player
1 pre amp
1 amplifier (4 inputs, 4 channel out)

you bridge 1+2 and connect this to 1 12" double coil sub woofer

the next 2 connect to 2 mid speakers example "rockford or ev 5 / 8 " and 2 tweeters for heights..

Thats a kicking tricked out basic car audio system,,,

Hope that helps you understand how it works..

Kenwood amp kac-x401m


How long will the bass play before the amp kicks into protection mode and how loud are you listening to it? I've noticed with my amps that if they don't have enough air flow they will get hot and kick into protection mode. They will also kick into protection mode if you are running it at more than it can handle. Check your adjustments on both your amp and the head unit. Make sure you are not running more bass than the amp can handle.

Bi-amp


After examining a picture of a 5802 ( I have been servicing adcom for over 20 years ), these are not bi amp posts, but bi wire posts.

Bi-amp means that 2 amps are being used, one for highs, one for lows. This means that you have no crossovers in the speakers, instead, you have an electronic crossover between the amps and the pre-amp. The highs and lows are separated in the electronic crossover. One amp handles the lows, one handles the highs.

Bi-wire means that you have the crossovers still inside the speakers. The amp handles the full range of music ( highs-mids-lows ). Different kinds of speaker wire produce different results. If you have bi-Wire terminals on your speaker, they come with shorting wires, that tie the tweeter + to the woofer + on the back of the speaker, and the tweeter - to the woofer - . When the shorting wires are removed completely, you have now electrically separated the tweeter and woofer from each other, while maintinaing the crossovers ( inside the speaker ) for each.When this is done, you can now bi-wire the speakers and amp, and use different kinds of wire for the lower frequencies and the upper frequencies, depending on your ears ( everyone hears a little differently, thats why there are so may makers of components, and wire ).

Why do we have crossovers?.....the tweeter voice coils ( the things that make the sound ) are made of hair thin wire. This wire cannot handle much power and if you were to put bass in to a tweeter, you would burn the tweeter out almost instantly. A tweeter is a very light, fast moving device which can react very quickly to high frequency sounds ( symbols, triangles, guitar strings....). Woofers are more rugged. They have voice coils made of heavier wire and are designed for larger movements that Bass demands. Subsequently, woofers aren't very good for high frequencies because they are slower devices.

So what do we do ?.....Keep the lows away from the tweter and the highs away from the woofer.....thats the job of the crossover.

In the event that your speaker has the crossover OUTSIDE the speaker box, you should check ( as always ) with the manufacturer of the speaker to see how it can be changed to suit your needs. Remember to always read and follow your owners manual. Good luck....Rob

Bass amp settings


For rock and slapping you are going to want to set the Bass and Treble controls high and the Mids low. For music such as Jazz you are going to want more mids so that your sound will be fatter. If there is a button marked "Mid-Scoop" you'll want that on when slapping.
