Sony MEX-1GP getting warm

Hey, hello everybody!

I have a Sony MEX-1GP car player with 4 speakers (3-way 60 W), and around 20 minutes with a MP3 playing, it get too hot (can't neither touch the heatsink) making the sound volume decrease 'til no sound. Then if I turn off the radio, wait some minutes and turn it back on, the volume came back. What should be the problem?

Re: Sony MEX-1GP getting warm

It's common for head units to run extremely hot when driving all 4 channels from the internal amplifier. If you can get some air flowing over the heatsink, it will help greatly. The smallest fan you can find will move enough air to reduce the temperature significantly (assuming it's placed where it can be effective).

A better option would be to use an external amplifier.

Why does my car stereo overheat after 15-20 minutes?

There clearly is a fault. Probably with the output or driver stage bias. Something is getting hot and as it heats its value is changing. It will probably need an engineer with a service sheet to locate the fault. It is rarely the obvious culprit...

Which speakers (Front/Rear) to buy that match Kenwood KAC-M846 4/3/2 Channel Amplifier.

I don,t no where you are reading thease articles from,I installed car audio equipment for over 40 years, Untill i retired a couple of months ago, Who ever is writeing those sort of articles does not have the slightest clue what they are talking about, It is the opposite way around, It is allway better for yor (Speakers) To handle more power then what your amp puts out, Then you will not blow the spaekers, It is best to get speakers at least 20 watts more then what your amps maximuin (RMS) Watts are, Hope this helps you out, (PS) 50 watts (RMS) Is what most people go for, It is in no means (Under) Powered.

My MTX Jack Hammer JH300 Amplifier is warming up... A red led indicates that the amplifier is warming up.I checked the conections and everything seems to be ok, I've a 10" Jack Hammer JH 4510 Sub...

Check the speaker connections from the amp to the box and inside the box to the sub. Its possible these came loose from vibration. Also gently push in on the sub. It should move freely and feel spongy. If it drags or is stiff the sub may be bad. Use an Ohm meter and test the sub. There is an Ohm rating on the sub (usually 4) and it should be close to that. Also check the audio in. Maybe the amp/sub combo is fine but there is no sound going in. Use an MP3 player with a 3.5MM to 2M RCA cable as an input. Start with the volume all the way down and SLOWLY raise the MP3 volume.

I installed a sony 600watt amp and it works but old rockford fosgate 200 hit harder how do i make my amp louder and evenly spread throughout my car

Hello jmanbutt99,

The old Rockford-Fosgate was probably producing the rated power. The Sony is most likely overrated. But, it's supposed to be stable on each individual channel down to 2 ohms and will deliver 65 watts RMS into that load. So to get the most from it, your best bet would be a pair of 4 ohm speakers paralleled to each channel. A relatively efficient speaker like the Kicker 07DS600's shown here should provide pretty good sound.

These will work with as little as 6 watts RMS and can handle up to 50 watts RMS so the Sony should power them really well. They're 4 ohm so a pair in parallel will present a 2 ohm load.

Hope this helps

Hey i had 2 car amps +for 4 speakers(140W maxi) and a sub 12inch

1 cap, either .5, 1 or 1.5 farad will be fine. they make 5 10 and 20 farad that cost way more than u need to spend for 400 watts RMS. i like the rockford fosgates, you can get a low cost Tsunami, just make sure you follow the charging instructions.

Does an mp3 player put out enough power for input to KAC-624 amp?

Have you connected the rca plugs to the radio or amp directly? If you've connected it to the radio make sure that the input level controls are adjusted AND available on that model (it will say AUX, INPUT, SUBWOOFER, REAR, etc.) Connecting your mp3 player directly to the amp will not have enough juice to hear sound you need to connect it to the radio first.

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.

I have Kicker ZX 650 4 channel amplifier and 4 DB drive PT6.2 mid range speaker. I want to hookup my speaker in 2 ohms. The operation manual for the amplifier can be used in 2 ohms. I need to know how to...

As far as I am aware you need to get 2 ohm speakers. I run a 4 ohm subwear as the Alpine Type R sub is 2 ohms. I'm not 100% on this though but you may get around it by bridging your speakers by connecting both speakers to the amp as normal but swapping the speakers negatives around! That may cause the amp to run as if only at 2 ohms. Hope this helped!
