I have 2 Carver amps, 1 is a M500T the other is a M500. I wanted to bridge these to refine amp power, increase channels. i don't have a users manual for either and wanted to know can they be bridged and how? thanks, Don Gallegos Snowy Colorado....

I'm using that Alpine right now for 2-12" subs and I have compared it to 6 or 7 other amps this month and most were 4 channel 150Watt/Channel Bridged to 300Watts x 2 and found the Alpine to be superior in both sound quality and loudness. The Alpine has also not turned off even with full volume for hours at a time, Very solid amp I was very surprised due to it's size!

I don't understand your question past, "It's handled......)

This really depends on the setup you intend to create in your vehicle.

The Amplifer (amp) needs to be matched to the speakers you intend to run.


As a rule of thumb, the power of the amp shouldn't exceed the max. power of the speaker (this may damage your speaker). Instead, the amp's RMS output power should be at 75-100% of the speaker's RATED (RMS) input power. NOTE: this must NOT be confused with max power.

Ideally, you want to run each speaker with its own amp channel.

A subwoofer will usually require a hi-power single channel amp, or a 2 channel amp, bridged into 1 (to increase power output required for the sub).

Here are some examples in simpler terms:

1 channel (hi power) amp can run a subwoofer.
2 channel amp can run 2 speakers, or 1 sub (bridged).
4 channel amp can run 4 speakers, or a combination of 2 spkrs + 1 sub (bridged), or perhaps 2 subs (bridged).

Hope this makes sense.

You don't (unless you want two B1520's on one channel and the sub on another). Reading the manuals would help.

The EP4000 amp drives only two channels. It CAN be bridged for one speaker but it won't support two channel and bridged mode simultaneously.

The B1520 subwoofeer is PASSIVE so it will need a dedicated amplifier to power it and control its volume independently of other speaker channels.

It's not bridgeable according to the manual.

Who specs an amp at 3 ohms anyway? Your Carver might be just as effectively powerful.

Check the wiring again and make sure that you have it bridged right and that the remote wire for the amp is hooked up

You need an amplifier with at least 200 wpc to get the most out of your BOSE. Look into getting a NAD, ADCOM or CARVER amplifier. I prefer CARVER myself. I am running a CARVER M-500T(251 wpc) on my 901's and they sound incredible.

Hello bdawson,

Maybe. Some, but not all, 4-channel amps can be bridged. You'll need to provide a specific brand and model number for a more definitive response.

On many bridgeable amps, the connections are shown right on the output terminals, usually the "+" of one channel and the "-" on another channel. The connection diagram in your user manual may also show which channels are bridgeable and the appropriate connections. Some amps may support what they call "tri-mode", powering both full-range speakers and subs at the same time.

Using a multi-channel amp with the channels bridged to power subs is a compromise. While you'll get an increase in power, it usually isn't as much as you would get from a monoblock. And fine tuning for the best sound is more complicated, balancing the filters and crossover so that the correct frequencies are sent to the appropriate speaker.

Hope this helps.

connect right channel speakers to amp left out if the problem fixed you will have a problem in amp itself.
if the problem remained you will have a problem in speaker itself test first with new cable and second with speaker cabinet,
