speaker puts the amp in diagnostic. AMPLIFIER OVERHEA TING AND SHUTTING DOWN
AMPLIFIER GOING INTO PROTECTION LACK OF BASS The most common cause for this problem is
when amplifiers are overloaded with speaker impedances lower than what they are rated for.
Doublecheck the impedance of your speakers and their wiring. Also check that no speaker leads are
shorted to the vehicle metal chassis. When an amplifier goes into protection mode, we have to first
establish whether the problem lies with the amplifier, or whether it is something in the installation.
Disconnect all RCA and speaker cables, leaving the power, ground and remote connections. T urn
the system on, and if the amplifier now powers up properly, add the RCA cables, and see if the
amplifier goes into protection. If not, proceed by reconnecting the speaker leads, etc.
By following this simple process of elimination, the fault can be diagnosed quite easily. The lack of
bass can be attributed to various causes. Check that the proper recommended enclosures have been
used for the woofers. Check the phasing of multiple woofers connected to one amplifier, as well as
those connected to multiple amplifiers. Refer to pages 10, 1 1 and 12. If the positive and negative
terminals are reversed in a two woofer system, you will get a cancellation which sounds like a lack of
bass. Always double check your wiring for proper phase. Position of woofer enclosures in the vehicle
will also affect bass output. Y ou should experiment with different box positions, firing forward,
backward or upwards to see which way you get more bass in to the cabin. HOW TO TROUBLE

powered by Verisign. If the protect remains then something with that speaker or wiring is bad BUT
if after disconnecting the rest of the speakers that you hooked up then theres is still a power issue
with your amp Single or dual voice coil. By what you said not getting hot sounds to me like the load
istoo much. Larry T Winona Lake, IN The amp goes into protection when the circuitry over heats.\
First decrease all your gains to minimal volume. See if the protection light comes on then. Next plug
in your RCA cables. Check protection light. Then plug in your subwoofer cables. See if you are still
in protect mode. Hopefully everything works alright again. Just slowly increase the gain to see what
the cutoff is.
Make sure you arent dropping the ohmage too low on the amplifier. Check manual for correct wiring
and such. Login to post On this Behringer powered mixer, the bridge switch simply connects the
power amp section inputs, the required way. At best the A channel will see too smaller impedance,
and hopefully shutdown. This is a Behringer, it has digital class D power amps, and it does Not claim
any amplifier protection !!! If the powered mixer works in normal stereo, then it is probably OK. If it
then does Not work in bridge mode it is likely to be the connector wiring. All the best. However yi\ou
must read the diode LED for diagnose. God bless youThis is an indication that theres something
wrong on the TV. Follow the steps below. Self diagnostic screens displays its log of error.
JdvillanuevaTo eliminate other possible problems, read through the following page Amp in
Protection Troubleshooting Let me know if you have any other questions.If you run 2 of them in
parallel you will get the 4 ohms. If you run 4 of them in parallel you will get the 2 ohms. In parallel I
mean that you connect the positives together and run them to the positive on the amp and the
connect the negatives together and run them to the negative on the amp. Let me know if you need
more help. Good Luck. Andrew HawkinsYou may have damaged it if you hooked your power and
trigger wire first and then the ground wire. Unhook EVERYTHING except the hot wire, ground wire
and trigger wire. If you still cant get the unit to come on then it is time for a trip to the repair shop.
Good luck.I can get some stations but not others, such as radio 1,3,4, but not 2. Answer questions,

The amp Im pushing it with is a Cadence Z4000 amp which is capable of providing 2 x 300w at 4
