Ohm Concept 12 Inch Dual 4 HZ Series Subwoofer Car Speaker - Answered Questions & Fixed issues
Crest Audio CPX 1500 help.
Read the manual!
The Bridge mode on stereo amplifiers is often misunderstood relating to actual operation and usage. In basic terms, when a 2-channel amplifier is operated in the Bridge mode, it is converted into a single-channel unit with a power rating equal to the sum of the power rating for each channel, at a load of twice that of the single- channel rating. For example, the CPX 1500 is rated at 750 watts RMS per channel into 2 ohms. The Bridge rating is 1500 watts RMS into 4 ohms (minimum load). Bridge mode operation is accomplished by placing the MODE switch in the BRIDGE position, using only the BRIDGE Speakon connector or the red binding posts for the output, and using the CHANNEL A input. All CHANNEL B input func-tions are defeated and serve no purpose now. Bridge mode operation can be used to drive sound distribution systems in very large public address applications. Another common use for the Bridge mode is in subwoofer applications where very high power levels are required to reproduce extremely low frequencies with ade- quate headroom. Such enclosures usually contain 2 or 4 loudspeakers to handle the power levels involved. For Bridge mode usage, the enclosure impedance must be 4 or 8 ohms. Never below 4 ohms.
I have an SPL z2x-820 amplifier, I want to bridge the two channels into one.y question is does it matter what kind of sub I get or as long as it handles the correct 2 ohm load and wattage I should be fine?
It is ok to bridge the two input channels - that is known as mono or monaural, but it isn't a good idea to bridge the outputs without knowing the type of output stages. You could try it but don't be surprised if it doesn't work longterm, certainly you must observe the polarity.
If it is your intention to use it as an amplifier to drive a subwoofer you will probably be disappointed by the performance due to the amplifier being built to deal with a wide spectrum of frequencies rather than being designed to amplify mostly subaural frequencies - certainly some filtering will be needed to block unwanted frequencies from the amplifier input.
Because the amplifier has the theoretic capability to pump out 230 watts per channel into a 2 ohm load, there is no necessity to provide a 2 ohm load, in fact it was probably designed as such so it could use 2 x 4 ohm speakers in parallel for each channel providing good power handling on a budget.
If I buy a pair of Yamaha CBR15 speakers , and I configure them as a 4 ohm load, how many watts is appropriate to drive that load?
Hi John, this CBR15 speaker model, is specified for real power handling 500 watts each speaker
If you connect the two Yamaha CBR15 in parallel, you will get an impedance of 4 ohms and an effective power handling capacity of 1000 watts, in this way you can apply that power, without risk of damage
I hope you serve my comment

Hola John, este modelo de bafle CBR15, esta especificado para manejo de potencia real 500 watts cada bafle
Si conectas los dos Yamaha CBR15 en paralelo, obtendras una impedancia de 4 ohms y una capacidad de manejo de potencia efectiva de 1000 watts, de esta manera puedes aplicar esa potencia, sin riesgo de da?o
Espero te sirva mi comentario
Saludos Franco Dosil

2 dvcoil 4ohm.subs, need 2 ohm load total for monoblok.amp. how do I wire.it
If you run one sub with the DVCs in parallel, you would get 2 ohms. If you run both subs with all DVCs in parallel, you would get 1 ohm.
If you run both subs with DVCs in parallel and subs in series, you would get 4 ohms.
If you run both subs with DVCs in series and subs in parallel, you would get 4 ohms.
If you run one sub DVCs in series and the other sub DVCs in parallel and both subs in parallel, you would get 1.6 ohms but the subs would not be balanced.
If you run both subs on only one coil and the subs in parallel, you would get 2 ohms (but only if the individual coils are rated for the full power)
Is there bluetooth on nsdn-w59
I have the same radio now with no Bluetooth am trying to get Bluetooth on it too without having to buy another radio. Please help.
