SOURCE: bridging to 12 inch kicker competition subs to my 1000 watt alpine 4 channel amp

I'm a bit confused. For Alpine amps, the "M" prefix is for monoblock (aka single channel) amps and the "F" prefix is for multichannel amps. The only M550 I find is an MRD-M550, which is a monoblock, not a 4 channel like you say.
Unfortunately, I can't give you accurate help until we know weather it's truly 1 channel or 4 channel. Then I'll be glad to help!

SOURCE: bridge subwoofers

Without looking up the individual specs of your speaker and amp, I'll offer a few basics when it comes to bridging an amp.
Most important...find out what impedance (ohm) that your amp can handle bridged!! If you go below this rating, you will run the risk and most likely eventually overheat and short circuit the amp. You must also know the impedance of your sub (which can come in a variety) to be able to match them. Depending on this impedance match-up, it may be less beneficial to bridge the speaker to this amp. For example if there is an impedance mismatch you'll either get less power from the amp or short circuit the amp. If you know these I can help you come up with the best solution.
If you know bridging is the best option, then you'll have to know which terminals on the amp to use in order to bridge. This is how it normally works. On a 2 channel amp...you would normally take the positive from one channel to the positive on the speaker, and the negative from the OTHER channel to the negative on the speaker...and this is how you bridge the amp. The other two channels would remain UNCONNECTED. BUT!!! you have to make sure you use the correct 2 channels...it varies from manufacturer. But take heed not overload the amp...and not to overpower the sub. There are a few different ways that you can configure the subs if you find it beneficial to bridge your amp, these would take long to explain and would depend on the impedance of your subs and specs of your amp...these wiring configurations is how you match the impedance of the speakers input to the amps output (and is very important to do correctly) Look up "parallel and series" wiring configurations. Let me know if this helps, or if you need further help. Find out the impedance of your subs and the specs of your amp and i'll be able to assist you more. Hope this helps.

SOURCE: dont know how to wire a subwoofer

Hello,

The Jensen XS1010 is a 4-ohm sub and should work properly off of the outputs of most any single channel monoblock sub amp or off a bridged 2-channel. You did not say what brand or type of amp you intend to use, but in any case, there's only 2 wires to connect to the sub, one positive (+) , the other negative (-). Simply match them up with the positive and negative on the amp speaker output and you are ready to bump.

Here's the link to Jensen's website:

http://mobile.jensen.com/jensen/

I'd recommend downloading the XS1010 manual. They recommend an enclosure with at least .75 CuFt internal volume.

If this helps, please rate it as "FixYa". Thanks!

I installed a 400 watt zapco competition amp\ front speakers play ...back woofers don't?


are you sure you didnt wire the amplifier the front and rear to
left/ right?

check your deck settings to see that the rear speaker rca are connected.
check all wires are connected.
push the mono or bridge buttons are off.

provide more info.

Can 2 ohm subs be used with a 4 ohm 2 channel amp?


You can but you will have to wire your subs in parallel....to a 4 ohm load then bridge it to your amplifier.....look up parallel wiring on google....Im pretty sure you will have to run jumper wires from your positive and negative of one sub to the positive and negative of the other sub.....then run the two wires to your amp bridged.....to make a 4ohm load.....let me know if that helps you and gd luck!!!!

I dont how to run the wire on the back of my alpine type r 1242d


you can connect speakers up any way around ,if its one speaker with 4 connections then these extra 2 terminals are often for a continue through to the next speaker along the line ,.just use a small 9v battery and then connect to two terminals to find a bleep as you touch two of the terminals then you know where to put your wires

I have a zapco refrence 750.2 has no sound output when bridged but works fine when i run a speaker to each channel. any ideas on whats wrong?


check your settings on your stereo and the amp make sure you have changed to 1 ohm on the amlifier for a briged connection to a subwoofer and change from lpf to hpf on the amp there should be a switch.

These subwoofers are dual 4 ohm voicecoils.

Parallel wiring the 2 voicecoils would net a 2 ohm mono load.

Connect both + on the sub to the + on the amp.
Connect both - on the sub to the - on the amp.

Many professionals simply jumper the 2 + and 2- on the sub.... then run 1 set of wires from one of the terminals to the amplifier.

Subwoofers


This will depend on the amplifiers capabilities.

I will give 2 different scenarios.

#1 Stereo configuration

If the amplifier supports an RMS power output close to the RMS input power of the subwoofers then run the amplifier in stereo mode. For example 150 watts RMS X 4 channels driven at 20-20khz. (If you can provide a model # for the subs and the amp your looking at I can help you further with this decision.

Wiring for this is easy and simply involves matching the connectors for 2 of the channels (Front or Rear) to each of the subwoofers.

#2 Mono Bridged mode.

If the amplifier is lower power but mono bridgable you can bridge two Pairs of channels and power each of the subwoofers this way.

Generally speaking a 2 channel bridgable amplifier will be able to at least combine the wattage of each channel into a single monural channel and in many cases its actually higher.

So you would bridge the front 2 channels into a single bridged mode for one subwoofer. and then you could bridge the read 2 channels into another bridged mono channel for your other sub woofer.

For example if you had bridgable amplifier thats 50 watts RMS X 4 you coudl very likely (Generalization based on quality of amplifier) send 150 watts RMS to each subwoofer.

Again I would need to know what amp you're refering to to provide specific wiring instructions. Many Bridging amplifiers either have a single switch that will send them to bridged mode or you would use the positive + terminal from one channel and the negative - terminal from the other channel or a combination of both.
