When I play music it works just fine then it suddenly goes in protection mode afther a random amount of time varrying from 2 secounds too 5 hours with adjusting on all the crap but it still goes in protection and when it does it wont work at all for a while. it's not hot at all, and the Player keeps going, checked for short circuted wires. have no idea what too do. Can this be anything with incorrect Input Gain levels and/or Hz setting on the Amp? or mabe bad grounding.? apriciate any help.

Re: Cadence FX500

The FX500 is 4 x 75 watts clean and 1 x 500 watts RMS @2 ohm mono. What subs are you running and what are the ohms per voice coil. Single or dual voice coil. By what you said (not getting hot) sounds to me like the load istoo much. Let me know.

I was/am a Cdence daler and I sold many of those amps without a problem Never had a bad one!

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!

Ok i got a mtx 12' 500 sub matched to a alpine mrd-m500 mono amp. The deck powers the 4 speakers, as i turn the volume up on my deck (alpine cde 100) the sub/amp cuts out at around volume 20-22 and E-3...

Sorry,after rereading your problem,I gave a wrong answer.Do you have the deck sub RCA pre-amps connected to the amp,then the wires from the amp to the sub?If you do,you need to check what the sub and amp are rated as such as,peak or rms.They are 2 completely different meanings.Greg

I have two 12 inch rockford p1 punches powered by an 800 watt sony explode amp (2 Channel) and i want to install another 15 inch kicker with a 1200 watt amp not sure the model, i got it from a friend and...

I have a similar setup & I just run the second amp straight off the other amp by running positive & remote wires directly from 1 amps positive & remote inputs to the others amps inputs. But my head unit has RCA inputs, (sub in & front & rear inputs) so from my 4 channel amp I run 2 6 inch alpine S's to the front to the front RCA inputs of the head unit, & 2 Pioneer 440w 6x9 inch speakers to the rear inputs. & my 800w 12 inch sub from my 2 channel amp to the sub woofer inputs on the head unit. Has blown my eardrums for nearly 12 months now great stuff! Hope this has helped

I am wondering about car amplifiers, I don't know what kind to get, I have Alpine 6.5" 2-Way Car Speakers (SPS-600), 80 watt as my front speakers, and Alpine 6 1/2" 2-Way Car Speakers (SPR-17C), 100 watt...

I would strongly recommend that you get a 5 channel amp that puts out 75watts rms per channel that will deliver between 200-300 watts to the sub channel. I use planet audio amps myself and they run strong all day every day-maybe you could look at a planet audio vrx 600.5(5-channel) it throws 100w x4 and 200 or 300 to the subs depending on the resistance of the sub. Good luck

Is there a wiring diagram for the nikkai EAPA450 Amp

Hi, if you still need a photocopy of instructions email me

If you want instructions in brief this involves POWER CONNECTIONS, PHONO LEAD & SPEAKER CONNECTIONS:

POWER (At the same time when routing these wires, I would connect the PHONO LEADS from the car cd player to the amp, if your car cd player only has 1 preout (1red & 1 white) then you will need two phono splitters, a female to 2 males. Phono leads carry the unamplified sound from cd player to the amp):
~ Permanent 12V+ (Thick lead that is fused direct from battery all the way to the amp, wire must be 20a to 30a +, hence 1cm diameter wire, known as AWG8, Maplin sell cheaper kits then most)
~ Amp REMOTE (A thin insulated cable (5a is OK) from car cd player amp remote wire, this turns the amp on when the cd player is on, if your car doesn't have an amp remote wire, suggest nearest ignition supply or seperate switch that you turn on when you want to turn on the amp)
~ GrouND 12V- (Insulated lead (20a to 30a) to nearest part of unpainted car chassis such as interior panel screw hole, instead of an insulated cable all the way from the batery, this is common practise.

Each speaker has a - negative & + positive, these must connected correctly. The amp has 4 channel, 2 channel labeled as front, 2 channels labeled as rear. Using speaker wire, connect cable from amp to speakers. Note: Ensure the speakers being connected only receive sound from the amp (Not cd player as well, as would damage players or at the very least impair sound)
The amp has a feature called bridgeable this means a sub 8" or 10" sub can be powered by 'bridging' two channels. For example there are 2 ways to bridge power a Sub on the NIKKAI EAPA450:
i) Sub speaker wire positive + to channel RL and Sub speaker wire negative - to channel RR.
ii) Sub speaker wire positive + to channel FL and Sub speaker wire negative - to channel FR.

~ Bass boost, meant to be on for a channel if using sub, otherwise off.
~ X-over mode adjust hi/lo frequencies, only work if both x-over switches are on! Then adjust switch frequency knob, until it sounds right.
~ Gain (Volume knob) adjust volume knob up or down, until it sounds right!

You will need patience! many hand tools and parts such as: Wiring kit, fuse holder 20a/30a, Phono leads, speaker cable, Fork/ring connectors, wire strippers, wire cutters, set of screw drivers, also ueful to have zip ties to tdy excess cable and 'P' cable clips to tidy speaker wire to shelf, etc.

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.

Do not have a sub output on receiver /do not know which wire to plug into the amp sub input/5 channel amp /have rca output for front and rear speakers

Hello southernbike,

With a 5-channel amp (stereo L/R front, stereo L/R rear, and subwoofer) you only need the two pair of stereo inputs.

You do not say which brand and model of amp you have, but most have an output configuration similar to the Alpine shown in this link. Connect the front and rear RCA's from your receiver, your vehicle speakers to the respective output terminals, and your subwoofer to the 5th channel terminals.

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.

How many speakers can I use?

This should work if channel 3 & 4 are bridged at 4 ohm.
channel 1 should be stable at 2ohm
channel 2 should be stable at 2 ohm
You can hook up the right side speakers together ( + with + and - with - ) . same thing with the left side. this will give you 2 ohm each channel. this will cause your amp to run hot (this might be tuff on the amp). It will give you right (2 speakers) and left ( 2 speakers ), no front and rear adjustement if you need to balance your sound. I think you should be better buying another amp for your sub and take your 4 channels for your 4 car speakers. this amp as a rca output that can feed the other amp ( sub amp ). it is possible to do it.

Good luck
