OK let's try this I have cerwin vega mobile audio speakers 2 pairs vega369x 6x9 @ 75 rms 4ohm and 1 sub 200 rms @4 Ohm want to wire them to a planet audio 1600watt 2Ohm 4ch amp


Your can go down to 2 ohm but will take 4 fine wire your 6 x 9 s to one side one ch each and bridge the sub across the other 2 channels.

There are 2 input ports on the sub woofer. How can i connect them to mono amp


subs usually allow a bridge where you connect the mono positive to one side positive and the mono negative to the other side negative. Does it not mention this in the instructions? If you don't have the instructions, try it. It can't hurt anything, but use low volume when checking. If you want to verify the bridge before hooking up, use an ohmmeter to look across the positive on one side to the negative on the other. If one combination is open or more than 8 ohms, try the other set of positive and cross-negative. OK?

We installed the amp and bass package and the subs are not nowhere near *** powerful we think its the amp and when the remote bass switch when we turn it it doesnt change


what product brand did you install. do you set the amps x-over and gains a sub sonic filter right
need to see if the amp is on check led light on amp. make sure your subs ohm load is correct for the amp.

let us an example fake amp 500x2channel max output 1000watts

if you wire your subs at 4 ohms you 250x2 rms stereo
if you wire your subs at 2 ohms you 500x2 rms stereo
if you wire your subs at 4 ohm mono you get 1000 watts

if you have the input voltage of 14.4 all the time at the amp

whats the equipment power

How can i bridge a mtx 9500 using a mono amp?


You cant bridge it to the MONO AMP . You can only bridge subs & speakers to 2 CH & 4 CH AMPS that are bridgeable. Because if it appears that there is 2 channels on a Mono amp its so its convenient for you to hook up 2 4ohm subs to it easily But both channels are actually connect internally together in parallel inside the amp unlike a 2 channel they are separate.

So just connect your mtx 9500 to a plus and a minus and doesnt matter which since all the + terminals of are connected together and - are connected together already.

Whats important is on the side of the sub/box it reads 2 ohms. The lower the ohms the more power the Mono amp will put out. Mono amps are designed to handle 2ohm loads.

If it reads 4ohms The MONO amp is the wrong amp to use cause the power will be weaker. So if you have a 1000 Watt Mono amp at 4ohms the sub will only get 500 WATTS Max while a 2 ohm will get the full 1000 Watts.

If it reads 4 ohms connect it to a 2CHANNEL AMP and BRIDGE IT (connect + of the sub to 1st channels positive of the amp then connect - of the sub to 2nd channels negative of the amp) . The power will be doubled when you bridge it on a 2 channel amp. NOW if it was a 2 ohm sub and you bridged it to the 2 channel amp it will fry the subs and ruin the amp. 2 CHANNELS CANT TAKE A 2OHM LOAD BRIDGED OK.

How do i bridge 2-4ohm dvc's to a mono block


If you have a DVC 4ohm speaker, and you are using both voice coils, the amp is seeing a 2ohm load.
If you bridge the amp, you CAN run both subs as long as the amp is Two Ohms Stable.
Wire each subs voice coils in parallel.(Positive to positve, neg to neg.) (2ohms) each.
Then wire the two subs in series.(Neg from amp to neg of sub one, pos of sub one to neg of sub two. then pos of sub two to pos of amp.

If it sounds too hard, leave it as you are already running the amp at two ohms.

What amp do i need to power a Polk Audio db1040DVCin brigded connection, i only plan to run one sub, i want to bridge the sub for better sound quality, and i'm buying straight polk, what do i need


Hello oran1891,

OK, you don't bridge subs. You bridge amps, if they are capable of being bridged (not all are).

Bridging is a method of connecting the channels of a multi-channel amp in such a way that the amp delivers the output of 2 stereo channels into a single mono load.

The Polk DB1040DVC is a sub with dual 4ohm voice coils. You can wire the voice coils to present a final 2ohm load (parallel) or a final 8ohm load (series). The rated power range is 50-270 watts RMS. Since you can parallel the voice coils and have them present a 2ohm load to the amp, you are looking for an amp that provides a minimum of 50 and a maximum of 270 (round it up to 300) watts into a 2ohm load. The Rockford-Fosgate Punch 300.1 shown here for $170 seems tailor made for your Sub. If you can make do with less power and want to spend a little less money, the Orion Cobalt CO500.1 will deliver 250 watts RMS at 2ohms and you can buy it for $140. The punch is a better deal. If you decide to add another sub later, it will power them both with 150 watts each, a little low, but still decent. If you want a 2-channel bridgeable amp, I'd recommend the Kicker 08DX3002 shown here for $200. Note that in bridged mode, it is not stable at 2ohms, only down to 4ohms.

Hope this helps.

How to wire 2 dvc subs to a orion 2150sx ? dont know the wire colors or how to hook um to my amp.


what impedence are the voicecoils?
Dual 4 - Dual 2 - Dual 1 ??

Orion SX / GS / HCCA amp Wiring guide:

Orange = Right Positive
Black/ Orange = Right Negative
Yellow = Left Positive
Black/ Yellow = Left Negative
Blue = 1+1

Bridging of SX or HCCA Amps:
1. Use the Orange wire for Positive.
2 Use the Black/ Yellow wire for Negative
3. Push "in" the Mono Button
That amplifier is only 4ohm mono stable - so assuming the subs are dual 4 ohm voicecoils...

First wire both in Parallel Independently So each subwoofer is now a 2 ohm load. (combine + and + - and- on both subwoofers)

Now Take a positive on one voicecoil of sub #1 and attach to amplifier+(orange)

Take a - on that same subwoofer and attach it to a + on the OTHER subwoofer.

Finally, take a - from the second woofer to the amplifier -(black/yellow)

Now you have a 4 ohm load on your bridged channels.

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.

I have a jbl W15GTi MKII 15 inch and on the speaker it has to a a an b side and two wires no each side how do you hook it up


Your speaker has dual voice coils. You can hook it up so that it is 2 ohm or 4 ohm depending on wat the amp can handle. You can try hooking it up by matching the colors or like any other speaker.

Need help bridging


First check your gain it may be turned down. I personally dont bridge speakers. I put each speaker to its own channel on the amp.Make sure positive to positive and negative to negative. Try hookin up two speakers to the amp (not bridged) and turn your gain up around half way. Make sure you amp is switch to lowpass not high since most amps have crossovers built in now. The more speakers you have the less output from each speaker from one amp youll get.
