I have 2 12'' subs 1300.watts and 2 1200watts amps both bridge to push 2400.00watts do not sound lond enoungh

impedance mismatch cud be the culprit. make sure ur speakers are the right ohms for ur amp. most amps are designed to operate on a 4 ohms speaker load on bridge mode. some amps are never designed for bridge mode. so if u bridge these amps u will get less output. u have to be very careful when u make the connections. plus when u bridge two amps for 4 ohms load, the total impedance becomes 8 ohms. make sure ur speakers are 8 ohms. few ohms can make big difference on power amps.

Marantz PM66SE AMP: The fuse in the board is burned after a few seconds when the power is on. COuld you please help me to diagonose the issue? Thanks a lot!

You have an overload in the power supply or audio output stages. Look around sometimes a part may be burnt, have a hole in it etc... In the power supply it could be a diode, the large Elec Caps, Bridge Rectifier, Voltage Regulator. In the Audio Output, one or more large transistors, on the heatsink, or an IC if it uses one.

Amplifier problem

Here's the basic problem. The DVD player can get a 5.1 audio source from the DVD. That signal is then converted from Digital to Analog and split into 6 channels of information. Each channel has an audio out on the back of your player. You are only using the Front L and Front R outputs. Based on how I read your description, they seem to be sent from your DVD to your TV, and then from your TV to your receiver. The problem is that you are only listening to two of the six channel, so you are losing a lot of information. How this sounds to you depends, in part, on how the sound is mixed on the DVD (5.1 versus just stereo, for example).

Because you don't have 5.1 system to take all six outputs (analog "DVD Audio" connections), you shouldn't be using those outputs. You could use the digital out (optical or coax SP/DIF) to send all channels to a receiver that could do the splitting (D/A), but it sounds like you don't have the equipment for that.

You didn't provide the model for the LG DVD, but there should be connections for analog stereo. They would be labeled as Audio Out L / R, or something similar. The connections are stereo, but your player would use all 5.1 channels to play through those stereo channels. You could connect those directly to your receiver, or you can continue trying to have the TV as a step in between (not suggested unless you just like to watch DVDs without turning on the receiver).

setup of bridge mono mode:-1-turn your amplifier off.2-connect input wiring to channel(1) input--3-connect speaker across positive outputs terminals-do not use negative terminal when amplifier is operating in bridge mono mode.4-turn down (fully counter clockwise)of channel (2).

Hi monmax,
I hope you are aware that in bridged mode your amp will become monaural (single channel, double power). If you still wish to bridge it:
Switch of power.
Set mode switch behind amp to "bridge" position.
Connect speaker positive to CH1+ve terminal of amp output and connect speaker negative to CH2 +ve terminal.
Be aware that now, in bridged mode your amps output power delivery is 1100 watts for a 4 ohm speaker and 900 watts for an 8 ohm speaker. Make sure your speaker can handle that.
