I have a Alpine pdx1.1000 on 2 12" db drive platinum series. when the bass hits its cuts off. If I unplug one sub it doesnt cut off and both subs work fine when I plug them in one at a time. its when both are plugged in it cuts off and comes back on. It worked fine until tonight. thanks in advance
i have 2 12" alpine type r subs and when i turn the volume up the amp cuts out and a red light turns on,on the amp. if i shut the car off turn it back on again it works fine for a bit then it happens again. i have aredy upgrader the wiring to 4 gadge to the amp and 12 gadge to the subsi have 2 12" alpine type r subs and when i turn the volume up the amp cuts out and a red light turns on,on the amp. if i shut the car off turn it back on again it works fine for a bit then it happens again. i have aredy upgrader the wiring to 4 gadge to the amp and 12 gadge to the subs
I have a alpine pdx1.1000 amplifier powering one Orion HCCA 12.4. This sub is a DVC 4-ohm sub. When i wire it in parallel,( positives to positives and negatives to negatives) and turn it up, the four 20A fuses blow whenever it hits a loud and low freq. note. I really don't know why that happens, the PDX 1.1000 should be stable at 2 ohms but it looks like its not.. Right now i have it wired in series (8 ohm load), it sounds good but i want to have it work under 2 ohms. Any suggestions or tips???

Hey there. i have a PDX 1.1000 with 2 12" Type R Subs. I had the same problem for a long time. but i upgraded my power cable from 4 gauge to 0 gauge and put another earth from the battery to the chasis. the bass hits alot harder now and rarely cuts out. except now im having the problem of the 4 25 amp fuses blowing on the amp....
You may have a problem with the power source feeding the amp. You need to check the voltage across the amplifier's B+ and ground terminals when the amp is playing/cutting off. If it's dropping below ~11 volts, you need to determine why it's dropping so low.

The vibration from the bass is cutting off the amp. it is a loose wire causing this issue. you can also get a stabilizer that will stop the vibrations from causing this issue.
You are probably running the ohms too low for the amp and its drawing too much current. Consult your amp manual for proper load level capacity and you can wire it accordingly. More then likely its only 4ohm stable bridged and your running it at 2 or less depending on if your subs have single or dual voice coils. Try connecting one pos speaker terminal to the other speaker neg then run the left ofer pos on one speaker and the the left over neg directly to the amp (series) I will raise the ohms (amp makes less power) but should not cut off unless the subs ohm are still to low, if this is the case you need a sub with a higher ohm rating or an amp wiht a lower rating...
ground is loose(most likely amp), battery running low, subs might be damaged? feel free to keep me in touch if problem occurs more after checking grounds and power source and subs. Also might need to re-tune your head unit and amp?
With an amp like that you can not pull enough power from you cars battery alone. That is why when it hits hard it drains the amps from your battery and you amplifier cuts out. The light on the amplifier most likely dims when the bass hits. You need to get a capacitor. They are easy to hook up on the main power wire. You can get one from http://phatcaraudio.com/capacitors.html or get a used one off ebay.com. Good luck
try to check and clean the wiring as clean as possible to avoid messing up on your connection. Check the polarity of you subs to yuor amp if you have it connected on the outher way around it would not give you a good result. check the polarity this will solve your problem. Over powering your sub will fry it easily try to tune it a 10" sub wont give you a 15" performance..
you've spent alot of money on **** by the sounds of it!!. you should only ever run multiple subs the same brand, power and resistance you can just connect any old subs to a system you need to wire them depending on the load that the amp needs to see. first thing is to try the amp/s on a individual sub to check your amps still work once done check the subs 1 by 1.
He may be right! You might try finding a new source of contact for your ground cause it may not be sufficent enough to ground to, also make sure that no wires from the back of your radio have any wires sticking out touching other interfering things that could possibly be causing the noise
It sounds like you either have too low of an ohm load or the voltage is dropping at the amplifier's power terminal.
With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.
If the voltage remains near or above 12v, disconnect one speaker and see if it shuts down. If it doesn't, disconnect that speaker and connect the other speaker. If it only shuts down with both speakers connected and the voltage is staying above 12v, the ohm load is probably too low and you'll need to rewire the speakers.
