I can never turn my cd player up past 14 because it will immediately overheat and cut out. I have a 1700 watt Kenwood amp and a box with 2 sony 12s and 2 mtx 12s. The subs are bridged inside so theres only 2 terminals on the outside. And i have my speaker wires bridged too. Is it overheating because of all 4 speakers being on 1 channel?

OK to be specific, its a Kenwood KAC-9102D 2 channel amp and it says 1 Ohm stable. RMS 500 watt (4 Ohms) RMS 850 watt (2 Ohms)
And all my wires are brand new and correctly installed. Im not a retard.

Start with the basics.
Undo every single wire set and make sure you got the (+) and (-) hooked up correctly. With many many things, if you run the power backwards you will get poor performance and/or problems related to increased Resistance to the current.
As you do this, have ALL of the instruction books open to the pages showing how the wiring is done. Sometimes one book will show something one way and the other book will show it another. (Like putting a horn in a Japanese car. They do it differently than we do.) Make sure the wiring is correct in relationship to both.
Also, read the fine print. When you start “bridging” stuff you can create a short. Also, you can change the Resistance, voltage and amperage. I would suggest you hook up ONE set of speakers and see if that works properly. I bet it does.
If your amplifier is NOT designed for four speakers (Quadraphonic)(Surround Sound) and only has output for two speakers, then the problem is you are trying to run too much off the amplifier regardless of how many “watts” it is listed at.
Either get a new amp or just use your best two speakers.
((Since this is in Car audio, if this is in a car, as you check for the correct wiring, make sure none of the wires damaged and shorting out on the car body.) )
Most amplifiers employ a protection circuit designed to shut the amplifier down before internal damage can occur. This protection circuit can be activated by any of the following:
The input sensitivity (gain control) may be set too high. Try reducing the gain to see if the amp still goes into protect
The amp may be getting too hot due to a lack of adequate ventilation provided in the installation. Check the temperature by holding your hand directly over the amp – if it is too hot to touch, it is too hot to operate reliably. Try to mount the amp in a location that has better ventilation.
The power and ground cable to the amp may be too light of a gauge, preventing the amp from getting enough current to provide its full output. Check the size that you installed against the manufacturer-recommended gauge, normally listed in the owner’s manual.
The impedance load connected to the amp may be below the minimum allowable – normally 2-ohm for stereo operation and 4-ohm for bridged “mono” operation. This could be due to too many speakers connected in an inappropriate wiring configuration, such as two 4-ohm speakers wired in parallel connected to the bridged output of the amp.
A short on the speaker wires also creates a low impedance condition.
There may be a defective speaker connected to the system, causing the amp to shut down to protect itself from damage. Try disconnecting all speakers, and test the system – one speaker at a time.
To correctly tune your system do the following:
1. Turn the input level control on the amp to minimum.
2. Play a CD and turn up the receiver’s volume control until you hear distortion on the speakers connected to the amp (this can happen even with low output).
3. When you begin to hear distortion, you have exceeded the maximum setting for the volume control on the receiver. Turn the volume down slightly until the distortion is eliminated. This is the highest clean signal available from the receiver.
4. Now you can turn up the input level on the amp. When you begin to hear distortion, turn the input level down slightly.
Exactly. The 4 speakers on one channel is a good way to fry older stereo equipment not enabled with automatic shutoff. If you have a two-channel amp, run ONE speaker to each channel. Using one of those combo boxes that has a sub, midrange, and tweeter (that filters and separates each frequency to the respective speaker) is the only way to connect two speakers to one channel safely. As far as “bridging” subs, I’ve never heard of that being done. Correction – I tried to do it years ago with a classic Pioneer receiver and fried an internal fuse. To fix this, your 1700W peak power amp (it wouldn’t be a 1700W RMS, trust me) should be connected ONE speaker to ONE channel. Don’t bridge unless you plan on running one speaker. And make sure the impedance range is +/- 2dB.
YES THEY ARE! You have to re-check if your amplifier is capable of handling 1ohm load because if not t will cut out and go into “protection” mode and eventually burn out! To solve this (assuming your amp is capable of handling 1ohm loads) you have to check the speaker wiring (series or parallel) and if your speakers have a single or a double voice coil the wiring pattern changes also. If anything give more details in the question above. With those speakers and that amount of power ARE YOU USING A CAPACITOR, HAVE YOU UPGRADED YOUR BATTERY, and WHAT GAUGE OF POWER WIRE ARE YOU USING?
ummm yeah you cant do that………i tried hooking up 2 12″ kenwoods and a 12″ type r on my mono amp and i blew a fuse after turning it up for a few mins. Best way to fix it is either hook up one pair of subs or get another amp to split the pair on to separate amps
its way too much power being drained, and over working your amp, try getting a bigger amp, a fan for your amp. many amps have built in amps to stop this.
yes–you are correct!4 speakers on 1 channel????your lucky you hav’nt blown your speakers or your amp![im assuming your amp has protection]do yourself a favor and get another amp so 2 speakers are on each amp!!
OK DID U WIRE ALL OF THE CORDS RIGHT AND IS THE AMP STILL IN GOOD CONDITION
be cuz its probably a suckey amp. i would go buy a new one or go to a music store and let em check it out
