How to connect speaker to dbx 150 mpa split spectrum amplifier

It would not be recommended, as the intent of the amplifier is to drive 5 individual speakers in a home theater setup. Bridging channels on the amp could cause damage and would definitely void your warranty. I would recommend simply not using two of the channels if you are looking to drive 3 speakers instead of 5.

It will drive the speakers but not the subwoofer. U need to connect the subwoofer pre- output from your amplifier to another amplifier that will drive the subwoofer.
If you connect the subwoofer directly to your amplifiers speaker output it will force the subwoofer to play the entire spectrum of frequencies (not designed to do that) consequently causing damage to the sub and maybe even the amp. So use the sub pre out.

hope this helped

dbx MPA-150 is a mono amp. It will take L&R speaker inputs from your receiver, filter out the bass and pass the mids and highs to the direct out terminals for your normal speakers. It then combines the bass signals to one channel, amplifies it, and sends it to the L&R subwolfer out terminals, (marked single speaker L+ and R-). If you have 2 subs connected, the L&R are wired in series internally, L- and R+ are jumpered. Thus 2x 4ohm speakers become 1x 8 ohm speaker, and the impedance switch should be set accordingly. The line level mode works quite the same way but subwolfer output only.

The speakers don't connect to the crossover at all. The number of speakers is determined by the amplifier and the impedence rating of the speakers involved. Perhaps you are not asking for the right information? If the above does not help, please update this with a more detailed description of what you need and I'll try to provide that info as well.

Thanks,

This will depend on whether your sub-woofer is powered (has it's own built in amplifier) or not. If it is not powered it will need connecting to an amplifier. If it is powered you will need a line level output either on the amp or the mixer.
Many modern amplifiers (and some mixers) have a dedicated output for sub-woofers in which case this is the best place for it because the higher frequencies will have been filtered out.
Some high quality amplifiers like the JAMO MPA 101 have a filter switch and adjustable filter level for powering sub-woofers. You then just connect the speaker to the speaker terminals in the normal way.

Otherwise on a p.a. mixer you could use the main output, one of the auxiliary, monitor or sub-mix outputs. If you are not using the main output you will need to route signal to the appropriate output accordingly. Either way your output signal will cover the full frequency range - your subwoofer may have built in filtering or you may need to use some sort of crossover to split the signal between the sub-woofer and the rest of your speaker system.

I have the same problem only its the left front speaker. I took my mp 5150 amp to a professional and he told me the problem is a modulator or the MU-1 part. This is a special part on the board that is designed by Monster and no one will have in stock. Each amplifier in this unit has its own MU-1. I am currently waiting further information.

Check the small electrolytics on the power supply board for high ESR, Very common problem on these amps. Protect circuit stays latched due to high ripple from PS.

I can almost guarantee that you'll find bad electrolytic caps on the power supply board to be the cause of the problem. I've seen several of these with the same problem. The protect circuit stays latched due to excessive ripple.

Might be a failing semiconductor component (usually an old transistor) in the amplifier's front end. This caused by the oxidation through the component legs or pin. I usually touch and move each transistor's body to exaggerate the noise. You can research also what kind of noise is it producing- intermittent, static, etc.
hope this helps..
