Why connect a car amp in series and will this help me?

I' ve got a 4 channel 1600 watt v-trek amp (can be bridged) and i want to connect two 1050 10" infinity subwoofers. When i connect the two subs in paralell the amp cuts out after about 15 minutes, so my question is, will connecting my amp in series illiminate my problem?

    You can connect them in series but that's essentially the same as connecting one per channel. Connecting one per channel is better than series bridged.



    This will effectively be 1/4 the impedance of the bridged parallel load. If the amp was going into protect due to an unsafe load, this will solve the problem.

Not sure if it's what was meant by previous poster. But if you're just driving the two subs off the 4 ch, and no other speakers, your best bet is to run pairs of bridged channels, ie use the 4 ch as a more powerful 2 ch amp. Then independently run one sub on each of these paired channels.

If you bridge all 4 channels (not sure if this is an option on this amp), and then run your subs in series, you will likely lose out compared to the peak power you could be seeing with two independently paired channels.

    And as stated by previous responder, if just using 2ch for bass, 2 for fullrange, then you're better to run one sub per channel, as you then have half-as-much current going through each channe, resulting in less heat and more available power. The added bonus is if the amp has decent damping, it will better be able to control the subs also!

I got 2 10in kicker comps and the rms on them each is 150 watts and can i hook them up to a 1000 watt sony xplod 2 channel amp and do i use both channel or just one or bridge them


1st thing is amps outputs have to be properly "loaded" this value is given in "ohms" if your amp says minimum speaker "loading" impedance is 4 ohms ( I suspect it does) then you may load that 1 channel down to only 4 ohms or amp will be damaged , most speakers are rated in ohm's Impedance (look for Greek symbol for omega) look for its rating somewhere on it doing the electrical formula math if you connect two 4 ohm speakers in parallel to one channel ( +=+ / -/- ) this divides down to 2 ohms (not good) but if you take same speakers and connect in series together (+to-/+to-) this gives you eight ohms (better) , the watts rating is a figure for you to determine the amount of power the speakers will take before failure , hence just because you connect 200 watt speakers to a 2000 watt amp is no indication that speaker will take all 2000 watts ( it will fail long before that point ) watts do ADD together like the above example two 4 ohm 250 watt speakers connected to one channel of amp in series will look like ONE 8 ohm 500 watt speaker to amp of course over 16 ohms load speaker volume will greatly diminish and amps have max impedance loads for them as well although there not often published
this is why I love the old TUBE!!! amps they load all the way down to 2 ohms and go up as far as 32 ohms load with no problems , they sound better as well across the board as well

You can't bridge that amp onto a load lower than 4 ohms. So you can't bridge that amp onto two 4 ohm subs. To get the most power out of your subs is easy. Run one channel to one sub and the other channel to the other sub. 165 watts RMS is plenty for most subs.

I have a PPI PCX-2400 and want to power two TREO subs that handle 2500 watts apiece. What is the best way to ire the PPI to these subs so that I get as much power from the amp to the subs without causing...


That would depend on the impedance (resistance) of the subs. Your best bet would be to use the full power of the amp to one channel (i.e. bridged) instead of to two separate channels (i.e. stereo). Two 4 ohm subs wired in parallel would present a 2 ohm load to the amp, which should allow you to get all 1600w out of it.

This explains series vs parallel quite well:

My amp and subs work but the subs dont sound very loud. how do i adjust my Pyle PLA4340 amp and fix this problem


Hello polarisracin,

You need to bridge 2 of the amp channels to each 4 ohm sub to get the most power from the amp. Bridge channels 1/2 to one of the subs and channels 3/4 to the other one. But the amp is only rated for 75 watts RMS per channel and Pyle products are sometimes rated higher than their real capabilities. So, even bridged and with the rated output, you'll only be getting at most 150 watts from a pair of bridged channels. That's not much for a sub.

Hope this helps.

Hello rattle822,

A pair of JH4512-04's can be wired to 2 ohms if the subs themselves are paralleled. There's only one voice coil and it's 4 ohm. If wired in series, the final impedance to the amp would be 8 ohms. They cannot be wired to 1 ohm.

In bridged mode, your 4-channel amp is only stable down to 4 ohms. You can bridge 2 of the channels to provide a relatively low 200 watts RMS X 2. The best power solution for your subs would be to bridge channels 1 and 2 and wire one sub to it. Likewise, bridge channels 3 and 4 and connect the other sub. If you connect both subs in parallel, the impedance will be too low causing the amp to overheat and possible fail.

As for the settings: Low pass filter on, crossover somewhere between 80-100, input levels to match your receiver, and bass boost to your personal preference.

Hope this helps.

Kicker 8 inch 4 ohm subwoofer 200 watts rms?


Max 200 W. You could bridge 2 channels of a 4 channel amp (or get a 2 ch amp and bridge it) and connect the sub. Bridging = connect + of sub to + of one channel, and connect - of sub to - of *other* channel. Check amp manual for instructions.

Don't get a mono - most are 300W or more - might burn the coil during loud passages.

Two terminals? bridging theory?


Hello again jm129852,

Having two power and ground terminals allows you to run two smaller wires instead of one big one. It's a convenience. No, you do not have to use them both. They are connected together inside. Yes, you should still use a single fused battery lead. Connect the big wire and fuse holder to the battery and to a distribution block and run the smaller wires from the output side of the distribution block.

When you connect the outputs of a two channel amp to two separate speakers, each speaker gets the power produced by it's channel only. If you are using only one speaker, and the amp is rated to operate bridged, then the speaker will receive the power from both channels, typically twice as much. You do need to be careful when using bridged mode because many amps will only operate safely at a higher impedance when bridged. For example, when operated with both channels connected to separate speakers (not bridged), it may be stable to 2 ohms. But when you connect both channels together (bridged), it is only stable to 4 ohms. Usually, the specifications will tell you the lowest impedance at which the amp should be operated. The specifications for the current RF Punch 500.2 are like this: 125 watts X 2 at 4 ohms; 250 watts X 2 at 2 ohms; 500 watts X 1 bridged at 4 ohms (4 ohm stable in bridged mode). You would NOT want to connect two 4 ohm subs in parallel to this amp in bridged mode. It would result in a final 2 ohm load and the amp would overheat and fail. One 4 ohm sub would be OK, and it would receive the full 500 watts as stated in the specifications. You could connect four 4 ohm subs, two each in parallel to each channel, and the 2 ohm loads on each channel would be OK. Or you could series two of them together for an 8 ohm load, do the same with the other two, and then parallel the two 8 ohm loads for a final impedance of 4 ohms and connect them into the bridged terminals. With DVC subs the connection possibilities get more complex. There are many good impedance calculators online that can help you determine the best wiring solution for various amp/sub combinations. I like the one above at the12v.com web site. Rockford-Fosgate also has one which allow you to select the a number of subs (up to 4), their voice coil configuration (single or dual), and the voice coil impedance. The RF calculator then shows you what configurations are available and what your final load impedance will be.

Hope this helps.

How do i bridge 3 subs to a 4 channel amp


My information shows the XM-1652Z as being a 2-channel amp. It will not be stable below 4-ohms in bridged mode. For best power, your subs will need to be 2-ohms with all 3 wired in series. This will present a 6-ohm load to the amp. After wiring the subs in series, connect the positive speaker wire to one channel (+) and the negative speaker wire to the other channel (-). For the 1652Z no other wiring is necessary. For subs you will also want to set the LPF (80Hz) switch to the "ON" position (to the right).

Keep in mind that the rated output is only 400 watts RMS at 4-ohms in bridged mode. That's kinda wimpy for 3 subs. You would probably obtain better results from two 2-ohm subs, each connected to a separate channel. That way each sub would be getting 200 watts RMS, still low but there's lots of good subs that will sound pretty loud with 150-200 watts

2006 12" Kicker L7 4 ohm


first whats the range in terms of WATTS that your 12" sub can handle in 4 OHMS ? second , lets check the AMP , POWER ACOUSTIK 1800 WATTS , Now thats a lot of power to drive a single 12" sub speaker . your amp is 1800 watts , per channel is around 500 watts , if BRIDGE thats around 1600 watts rms for ONE channel , if your sub can handle that kind of wattage fine , but it will not blow the amp , what it does is shuts down , some kind of protection mode , it will come back on after a minute or so. I suggest to use one channel in stereo mode , or purchase another sub to use the other channel. i hope this helps AJ
