It depends on the amplifier your are going to run. if you bridge the tens together that will give you an 8ohm load. say the the amp is 2-4 ohms stable, then you would be fine

I have a plad213 what load impendance am i running it i hook up 2 4ohm speakers in series bridged on that amp and how many watts RMS am i getting per speaker


2 4 ohm speakers wired in series is 8 ohms and then is dropped back down to 4 ohms when you bridge it.

2 4 ohm speakers wired in parallel is 2 ohms then dropped down to 1 ohm when bridged
(most amplifiers will not handle loads below 2 ohms)

hope this info helps

How do you bridge the jl audio 450/4


Nice amplifier. However it is best suited for speakers and not for sub woofers. Connect the plus (+) from speaker output 1 and the minus (-) from speaker output 2. Connect the plus (+) from speaker output 3 and the minus (-) from speaker output 4. Now the amplifier is in bridge mode, which will give you 300 WATT RMS at 4 OHM load. If you are bridging the amplifier to run sub woofers then do not forget to set the X- Over to LPF on the channels that you are planning to bridge. Whatever you do, make sure that the load you are asking the amplifier to play is no lower than 4 OHM. Playing this amplifier in bridged mode lower than 4 OHM is a recipe for trouble.

I'm planning on installing a system in my pick-up and I was hoping I could get a little assistance. I was planning on using a pair of 5'' McIntosh ms486 coaxial speakers (120w max 4 ohm)in the front doors...


First of all use the larger output amp to power the sub. You can tell if its free-to-air if in the middle of the magnet there is a hole for "air" to flow freely. The advantage of free to air is they dont require much of an enclosure or next to none so you can mount it on a single piece of mdf wood and use the cab in the truck as an enclouse itself. I would bridge the amp for the sub to mono but be careful to tune so you dont "distort". Secondly the amp for the mid's shouldn't be bridged any maybe you could run the front and rear speakers off the same amp.. I would get an amp for rear and front speakers each and one for the sub. Your ouput rca's should goto the cross-over first then to the amp (sub) - then wired to your sub (mono) which is bridged. Ensure to tune your cross-over to lowest frequency for sub. Its easy to bridge an amp if its 4 channel.. looking at the speaker terminals it will look like ( + - + -) use the two outer most terminals to bridge to mono.

It has an A and B channel for spkrs and i have one spkr bridged. do i split the neg to side a and pos to side b or just use one of the channels?


Could you elaborate on how the speaker is bridged?

I think you want to hook up a single speaker to a stereo speaker output.

In this case, you would strap (bridge?) the right and left speaker terminals by running a short wire from A right negative to A left negative. Then strap A right positive to A left positive -- this will give you mono output on either of the right or left speaker terminals -- connect your speaker to either one of these.

Do you know what the ohm rating is for the speaker outs on the amp and also the speaker itself?

What do you mean by the subs should have more watts than the amp.and subs mean woofer ? actually i dont know any thing abt this. what is 8 ohm stereo, 8 ohm bridged,4 ohm stereo. etc etc...?


If your planning on using a stereo system in your car or home you need to follow some rules otherwise your just wasting money. The watts of a speaker means how much power it can handle. The higher the number the more power it can handle, and usually the louder it can get without distorting. If your amp has more power or close to the wattage rating of the speaker you will blow the speaker, it can even get so hot it ignites. The amount of ohms is the electrical resistance the speaker provides. House speakers usually have 8 ohms where car speakers tend to use 4. 8 ohm stereo means your left and your right are separate channels and each speaker has 8 ohms. 8 ohms bridged means you bridge the left and right channel to increase the power output of the amp and you have to use either 1 8 ohm speaker, or 2 4ohm speakers in parallel to prevent damage to the system. Same goes for 4 ohms. If I remember correctly you want your sub(woofer) to have a wattage rating 20% higher than the amp. Remember if the speaker overheats its no good, but most amps if they overheat they just shut off until they cool off, but only if they state they have a thermal overload protection.

I'm having problems getting full power to my sub.


A 2 ohm stable amp should be able to be bridged to 1 ohm (consult owner's manual for bridgability), but a 4 ohm speaker is a 4 ohm speaker and would need to be parallelled with another 4 ohm speaker to provide a 2 ohm load.

You probably have the output bridged at 2 ohms. This amp is not a 2 ohm bridged stable amp. It is 2 ohm stable only in stereo. That means each channel can be 2 ohms, buts not bridged at 2 ohms.

If you have two 4 ohm speakers that are wired in parallel and then you bridge them, you have a 2 ohm load.

They only safe way to use two 4 ohm speakers is to run one speaker to each channel and then you have a stereo 4 ohm load.

When you use a 2 ohm load you get twice the current draw thru the amplifier as you would with a 4 ohm load. That means that the fuse you are using, the rating the amplifier is designed for, will blow any time you have a big bass hit.

If you are not using a 2 ohm bridged load, and you are using a 4 ohm bridged or something the amplifier is rated for, and you still have this problem, you may have a bad speaker. Even a speaker that will play can sometimes be on the brink of shorting out and causing the amplifier to draw lots more current than it is rated for.

If this is the case, you should go and get your speakers checked and see if they are still measuring at 4 ohms or at least close to it. Most speakers will measure a little lower than what the are rated. It is not unusual for a 4 ohm speaker to measure at 3.5 ohms, but if it is less than that, you problem is the speaker. Even if the speaker still plays.

I hope this was helpful for you, if you require any further help just ask.

If you did find that this was helpful in solving your problem, I would really appreciate a good rating.
Thanks and have a great day,

Sony XM-DS1300 amp


If they have bridged the outputs of the amp, be sure that the "ohms" load is 8 ohms. This would then apply a 4 ohm load to each of the output channels. It sounds like they have bridged the output or else hooked up the speakers in a paralled configuration that is trying to kill your amp. If you are using dual voice coil speakers then you have to treat each of the voice coils as a seperate 4 ohm speaker and wire accordingly. You need to correct this NOW or else you will fry your amp. Good luck.

ASSUMING that the amp is OK with a 2ohm load then you "set it up" by the configuration of the speakers you use. Two 4 ohm speakers if parallel will give you a 2 ohm load. However, if you are bridging the ouputs then a single 4 ohm speaker bridged between the two outputs will put a 2 ohm load on each channel. Be very careful if you are bridging the outputs that you know what you are doing. On average, when bridged wrong (too much load) the amp will last about one month before it fries. Get some help if you are bridging. Be sure not sorry.

My Kenwood 800watt amplifier


Sounds like you have overloaded your amp. When you bridge you MUST make sure that you still have the proper speaker load. One 4 ohm speaker on one channel is fine, but when you bridge that same 4 ohm speaker, it gives you a 2 ohm load on each of the two channels that are now bridged. If you made the mistake of wiring two 4 ohm speakers in parallel (plus to plus and minus to minus) then when you bridge you will be driving a one ohm load on each channel. This is very close to a dead short. Stop using your amp at once until you get your speaker load correct. This will damage your amp and it will cause you to have to go to a repair shop to fix it. DO NOT RUN YOUR AMP ANYMORE UNTIL YOU FIX THIS. Good luck.
