There may be a loose connection, or the fuse in the amp just simply isnt high enough for the input your speakers need. try changing the fuse for a higher one, if the fuse wasnt good enough to cope with the output this could cause the amp to shut down.

Hi this is amber I have 2x4 ohm qvc audiobahn abass2012P how would I correctly run them to get best bass n max power efficiency I have a soundstream Picasso 1000watt 4 channel bridge able amp to hook em up...

I assume you are replacing the built-in Audiobahn power amplifier with your 4 channel Soundstream amp. If so, you can set the Soundstream for bridge mode which should net you 2 high power channels of 250Wrms@4ohms or 500Wrms total power (if the speakers are quad VC), or alternatively, non bridged for 4x125Wrms (if the speakers are dual VC). You can see why below.
Next, you need to confirm each subwoofers coil configuration as follows: If each woofer is quad, there will be 8 connectors; if dual VC, then there will be 4 connectors. For dual VC, if each VC is 4ohm, you can choose between 8 or 2 ohms by series or parallel wiring. If each VC is 2 ohm, you can have 4 ohms in series to use. This can be determined with an ohm meter across one set of VC terminals. If you can get 4 ohm for each speaker, this will allow you to use the 2 channel bridged mode with each speaker getting the full 250W. If each VC is 2 ohm, use non bridged mode and run each of the 4 channels to each VC. For this case, use a 2 to 1 RCA jack to sum the two channels for each speaker on the amp's input side to make the signal 2 channel instead of 4 channel. Below are examples of quad and dual VC for reference only, the wiring may not match your setup which will depend on your VC resistance (impedance) measurement. Don't forget to set your HPF(High Pass Filter) as this is a subwoofer setup.

Wiring diagram for dual voicecoil subwoofer

To wire a DVC subwoofer, treat it (in the diagrams) as two seperate speakers, called coil one and coil two. This makes things easier.

To wire them up, wiring them in series would be safer, but if the amp is 2 ohm stable, put them in parallel. Look up dual voice coil wiring in google imagesfor more information and pictures.

I need to hook up two audiobahn A1200Q subs to a A1300hcq amp

The amplifier is only stable to 2 ohms.
Assuming the cubs are dual 4 ohm voicecoils - a 2 ohm load with 2 subs is not possible.
You can only wire up 1 dual 4 ohm voicecoil sub (both positives to amp... and both negatives to amp) to get a 2 ohm mono load.

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.

Jl audio 10w6 x zapco350

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.

ICBM-DIGITAL MONO-Channel 2000W AMPLIFIER speaker much

Look into competition lines of different manufacturers.... Massive Audio DMX, Soundstream, Atomic APX, Incriminator Audio Death Penalty Series, Kicker Solo X etc. In car audio, you have to pay to play. Dont expect a 100.00 subwoofer to take 2000W continuously.
Massive Audio offers a no questions asked warranty. Even covers blown voicecoils!

Aplifier gettieng protection signal and excess heat

for that amplifier, it is recommended that you are driving a 4 ohm load. It can drive a 2 ohm load, but will produce more heat and shorten the life of the amplifier. Is the subwoofer a single or dual voice coil? You'll want to make sure that you're not running below a 2 ohm load or you'll always go into protection. Also, try disconnecting the speaker wire completely from the amp so nothing but power is connected. If the amplifier is still in protection mode when no speakers are hooked up, then the amp is bad and will need repair or replacement.

Blown subs

HOW do you have it wired and what is the ohms rated on the subs
and is this amp bridgeable and at what ohms is it stable at
Do you have it Bridge to the subs to lower the ohms( Series or in Parallel)
Is the amp running hotter the normal and do you have it in a well ventilated are of your car/truck
Most car audio or at 4ohms and also is the subs dual
