SOURCE: alpine amp and subs questions

it will depend on how you use the 2 alpine subs,, do you know what there individual impedance is [ ohms ] and how you intend on wiring them,,,in series, in parallel, in any case you must maintain the min load in order to load the amplifier properly,,,otherwise the amplifier will operate improperly and allow DC [ direct current ] to pass and fry your subs...so what I really need is more in formation

SOURCE: AMP turns ON then turns off

The power antenna wire only supplies 12vdc when the radio is on. When CD or other sources are selected, the power antenna wire goes to 0vdc. The remote turn-on wire provides 12vdc whenever the head-unit is on. If your amps are powered on only when the radio is turned on, I would bet that you have the power antenna wire connected and not the remote turnon wire.

SOURCE: power light on the amp goes on after 5 sec off ultra linear 1200

If you run the remote from the battery you will need a on/off switch. Sounds like the amp is overheating. Also, I don't understand bridge the remote and power. They should be seperate going into the amp.

Check that the amp ground wire is grounded inside the trunk to an unpainted surface. No paint. Scrape it off.

Can i use a 10 amp power supply run my cobra 29 and 100 watt linear


I will answer the question. Figuring that 10 amps is continuous not peak. 10 amp multiplied by 12.5 it should be good for 125 watts. But you are on the ragged edge. I do agree you should lower dreaded key but you did not ask that question. But a swing kit will solve that. That is amusing SSB and the 80 watt cobra 29 comments.

Trying to find the right size linear amp to hook up to my Galaxy dx 949. I want max in/outputs. tired of being talked over. I have a Golden Eagle 150w amp, but have not connected it


That linear will be good for 100 watts of clean power. It has two MRF455 transistor which are 60 watts a piece. The cb will drive it with the carrier or dead key reduced to about 1.5 to 2 watts but i suggest that you read the linear's power while adjusting dead key not exceeding the 100 watts pep with voice. An NPC mod would be a good addition to get the modulation up with a low dead key.

Before you start the projection make sure you antenna system is in good condition high SWR will smake you linear in a hurry.

In factory condition 949 galaxy with a 3.8 carrier it will drive a 667v TexasStar. It is a low drive linear that will end all disputes as to who has more power. 8 out of 10 birds that escape will die of cancer withiin 72 hrs. Ok could not help myself. I would not suggest that unless you just want to damage other peoples receive. The v is for variable power. Hope this was of help.

Can a 19 ultra power be turned down to 1 watt? If so where?


Yes it can, but it requires the addition of some components. It isn't really a straight forward install. It needs some reworking. In my opinion, not worth the trouble.

Sounds like you want to run a linear amplifier. If you really want to run an amp, get a better radio to do it. There really is no other reason to lower the dead key that low. Also, 1 watt might be too low. May not drive the amp well.

If you just want to make the radio swing, 1 watt is way way too low. You will have barely any carrier and the radio will sound like ****. That radio stock dead keys 2.5 watts. That's perfect for swing. Now you just need to have more modulation. Find DM1 and unsolder 1 leg and pull it out of the board. Now you will have full modulation. You will deadkey 2.5 and swing to about 15 watts.

If you want to run an amp, get a good radio. If you like cobra, get a cobra 29. They are fairly cheap, and sound amazing. As well it is real easy to lower the dead key in that radio.

Got subs in the trunk -- 1000 watt with a 1200 watt amp.. Amp shuts off every time I raise my music above 20. My uncle is a professional and did it himself. The amp goes into safety mode. We checked...


Seems that the output stages of amp are blown and it shuts down for self preservation. When you do a lot of blasting amp failure is common especially if you use an equalizer to "soup things up." If you are blasting along at 1000 watts and you add 3 db of boost at a frequency the amp will double the power at that point, If you go up 6 db now the power is up to 4000 and exponentially. And transistors are not like tubes that know their limits.- given the chance they will simply blow themselves away providing power they do not have! You have to be careful at high volume levels.

Amp


you want to put a 30A into the amp and the inline fuse that you put onto the wire should be greater than 30A but not too high for what the wire is rated. The best bet for wire is to buy a wiring kit which comes with fuse holder, right size fuse, wire for main power ground and remote. You may want to double check what is written on amp for the size to put in there. Technically you can put a 100A onto the wire if it is big enough and the fuse on amp will protect the amp from problems. Hope this helps, Good Luck

Will 25 amp power supply pull 250-linear?


Yes it could, but... but it also depends on your antenna, what antenna are you using. Do not upgrade the power of your radio unless you know your antenna can handle the output power.
