Question about Audiopipe AP-2004 Car Amp

Open Question

I have a brand new Audiopipe AP-2004 amp. I have it running as a 4 channel amp powering a set of Alpine Type-R 6.5" components and a set of Alpine Type-S 6"x9" speakers. The problem I'm having is that it keeps cutting in and out. Like the Thermal protection circuits keep clipping on and off. I checked the amp and it was really hot to the point I couldn't keep my hand on it. This happens within 5-10 minutes of playing music! Any ideas what could be causing this issue? I though it was the amp so I replaced it with the same model and still have the same issue. Please help!!!

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted or, again, evaluate the impedance load. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as a possible root cause for intermittent shutdown.

SOURCE: my audiopipe amp went into

Ok, for starters you need to clarify if you are saying you have "two" fuses on your power wire. That's what I get from your statement. My question would be why? As long as you place the initial fuse within 12 inches of the battery, you're cool. The purpose is to stop the flow of power in the event of a spike so that your power wire doesn't fry and cause a fire under your vehicle carpet. Second, your amplifier should have fuses that trip when this occurs too. If this has been occuring since you installed the amp, you need to recheck all your wiring (I recommend removing the extra inline fuse). Two things trigger an amps safety mode. 1- an amperage fluctuation or overload. It will sense when there is to high or too low of an amperage flow. Too much fluctuation can damage internal components. 2- Your amp is malfunctioning. If you have an internal short, this could occur. (really it's tied to the first one because it is sensing that the short is allowing a full flow of power at the short, thus causing a fluctuation). Start with the ground wire. Most amperage problems happen because of a poor ground. Think of power like water. If you have a good flow coming in, but poor flow going out, it gets kinda....backed up. This causes a fluctuation of the amperage since the electrons cannot flow properly. Setting off the protection. The other thing to thing about is the correct guage of wire. If you have too small guage wire, the amperage will dip low during heavy usage, causing the other extreme of the fluctuation.

Check what you have. If you are running a load of 50-65 amp (look at the fuses on your amps and add them up), then 4 guage is good from 13-22 feet. If you are running any higher than that, you will need 2 or 0 guage wire. You will also need to make sure to have a fuse slightly higher that the amperage draw you are expecting. As always, make sure your power and ground wire match. I have seen alot of kits made with smaller guage ground wire. They work of the premise that the shorter distance produces less resistance, thus requiring smaller guage wire. I say why risk it. Always use a multimeter when checking for proper ground placement. Also, if you are going to use aluminum or tinned wire (trust me, it's out there), you will need to increase the guage of the wire.

Happy hunting

What amp would be better to use with what speakers/sub? I have a KAC-7202 kenwood 920W maximum power (150wX2 RMS, 4ohms) (230wX2 RMS 2ohms) and then the other amp I have is a Alpine MRP-M500 mono power...


I'm using that Alpine right now for 2-12" subs and I have compared it to 6 or 7 other amps this month and most were 4 channel 150Watt/Channel Bridged to 300Watts x 2 and found the Alpine to be superior in both sound quality and loudness. The Alpine has also not turned off even with full volume for hours at a time, Very solid amp I was very surprised due to it's size!

How should I wire a 4 channel amp for alpine sps 600, 609


they are only 4 ohm speakers so just put the front speakers on channels 1&2 or a&b and the rear on 3&4 or c&d since you are using a 4 channel amp thats what they are designed for

I have 2 6x9 speakers up front 4 6 1/2 3-ways


Hello rjmiller4039,

Although amps with 5 channels are pretty rare, you can get one. Alpine, Boston Acoustics, Infinity, JL audio, MTX, and Polk all have 5-channels ranging in price from around $350 up to around $1,000. The Alpine PDX-5 will output 75X4 watts RMS for the front and rear stereo channels and 300 watts to the mono sub channel. It is priced at $599.99 at Crutchfield.

Hope this helps.

Amplifier displays "CUR"


Hello anwbrown,

The "CUR" display means that the amp is drawing excessive current and the protection circuit is activating. Too low impedance or shorted speakers will cause the amp to draw excessive current.

The Alpine V12 is a Class D mono amp with only one set of speaker outputs. All versions, M301, M501, and M1001 are only stable to 2ohms. Assuming that all 6 of your connected subwoofers and speakers are 4ohm and they're all connected in parallel, the amp sees a .67 ohm load, far below it's rated impedance.

When brand new, the amp could probably operate at low to moderate volume levels without drawing excessive current. But as electronic components age, their tolerances change and they become less able to withstand excessive current or mismatched impedances.

I'd get a 4-channel amp and drive the 4" speakers off the front channels and the 6X9's off the rear channels. And just power the subs off the V12 making sure that they are connected to show a minimum load of 2ohms.

Hope this helps.

Alpine pdx 1.000 keeps cutting out


You are going to want to make sure all your power wires and grounds are 4 gauge as well as the wire leads to and from the capacitor-4 gauge also. make sure you have a very good ground - the power wire from the battery should hit a distribution block-from the dist. block a 4 gauge should go to the capacitor another 4 gauge to the mono amp and another to the 4 channel amp -every component should have a good solid ground even if you have to bust out a grinder and a drill and some self tapping sheet metal screws and go nuts on it- see if that helps you

PXA-H700 optimum set up...


The way the EQ is hooked up is correct.

You set the factory radio to a set level, then use the volume on the EQ for everyday adjustments.

I believe your problem lies in the amplification.
Your BOSE amplifier was made to run a 4 channel 8ohm stero load.
Low powered - high in sound quality.

You have swapped the factory 8 ohm speakers (15W) for 4 ohm power hungry ones.
Now the amplifier is working harder to produce the same output.

You would be best served eliminating the factory amplifier and getting 1 good 4 or 5 channel amp to power your speakers.

a 4 channel amplifier could be used stereo (left and right) on channels 1 and 2, (2ohm stereo load)
and bridge channels 3 and 4 for your subwoofer.

For a true surround sound - a 5 channel amplifier could run each speaker individually, and the 5th channel is reserved for the subwoofer.

a small dedicated 75wx4 channel amplifier with built in crossover, and level gain controls - would blow your socks off. It is 200x better than the factory 12Watt amplifier. Your ears will love you for it :D

If you need more help - just let me know.

How too hook my kac 7201 up to my two dual 4 ohm Alpine type Rs


Hello manbearpig65,

Well, that's a 2-channel amp, so it's really best used to power a set of regular speakers.

The best power solution, for your existing components, is to wire each of your subs voice coils in parallel, resulting in a 2 ohm load, and then run each sub off a separate channel from the amp.

The amp is stable only to 4 ohms in bridged mode, so you would series the sub voice coils (8 ohm load) and then parallel them (4 ohm load) to the amp bridged connection. This will result in less power to each sub than if you ran them separately.

Hope this helps.

As long as the crossover keeps the frequency going to the tweeters within a safe range (I'd say about 500hz+, read the box or look it up by model number) they should be just fine. That is what the crossover is for.

3 amps 2 subs sound system for car, need wiring help


As i read your problem i can recommend you that connecting each of the hifonics amp to each hifonics sub with the same specs by getting the specs in interfacing the two or you can simply look to the output of the amp and the input of the sub and find a suitable plug that fits to them.

In the case if you want to run each hamp to individually run each sub but sharing 3 farad capacitor: what i can suggest is that you connect in parallel one connecting wire of each input or ouput of the amp or sub. Its like connecting a connector from each of the input or output of the amp or sub to one leg of the capacitor, and connecting two wires to the other leg, one is being connected to the amp or sub and the other wire is connected to the other amp or sub.

In the case of putting a circuit breaker at the car battery: what i can suggest is that you find an appropriate circuit breaker that fits the specs of the car battery then connect it in series on the positive supply or read the specs of the circuit breaker before you connect it to the battery. Having a circuit breaker is like having a fuse but with special advantages in favor of the circuit breaker.

In the case of having power to the amps you can run one power wire to the amps by dividing the power wire into two, one connected to the amp and the other wire to the other amp. Then you can connect each amp and sub in series individually by connecting one wire b/w amp and sub. I hope i solved your problem
