Hooking my amp from my subs to run the rest of my speakers in my car
I have a legacy 400x2 amp that runs my subs I would like to be able to run the rest of my car speakers off the amp as well....It has high pass and low pass capablities......but clueless on how to do it

Depending on the PA FUBAR you have. The voice coil on those subs are DVC. Dual Voice Coil. You need to know a couple things. What kind of amp are you going to run on it. And what is the resistance (OHM) rating of each voice coil. MY two 12's are dual 4 ohm. Meaning that there are essentially 4 speakers to hook up. My amp currently is not 2 ohm stable in bridged. So what I did is run each speaker in parallel (red2red,black2black) then run to the box terminal. So now the dual 4 ohm voice coils are basically 2 ohm. I have 2 speakers. Now I hook the box up in series. To bring the now two 2 ohm speakers into one 4 ohm speaker. This is called series/parallel setup. My amp sees this box as 1 channel @ 4ohms. The downfall to this is the output of the amp is divided up into each speaker. So instead of sending all 1400 watts to one sub. I will send 700 to each sub. But here is a catch. even though each speaker is half the total wattage it will still be 3db louder. Meaning it will be as loud as 1 sub running 1400 watts. To conclude i need to know how many of those subs you are going to run on the amp.. And the model number of the amp so I can match up your wiring.
have you got a wiring kit for the amp? the amp needs atleast an 8 guage tho id suggest a 4 guage running from the batter to the amp with a 50 to 80 amp fuse atleast, then it needs to be ground to the chassis. a remote wire then needs to be run from the back of the headunit so that the amp only turns on when the ignition is on, then hook the wires from the amp to the sub.
forget hooking this on a subwoofer. this amp produces only 50 watts per channel at 4ohms or 70 watts per channel at 2 ohms RMS...
If you try bridging the sub, it will only give out maybe 100watts bridged.
if your sub is, lets say 1000watts RMS, youre just going to bust your amplifier to smoke...
Find a more decent and powerful amp. This amp is only intended for separates and lowend subs with an RMS of 80 to 150 watts
ok here is how it goes power wire from the battery all the way to amp..then ground wire from amp to a good ground on car then the remote wire which you have to run from the amp to the back of your stereo which in most cases is blue then hook subs from the sub box to the amp
your only choice is to run the amplifier at a 4 ohm mono load - this will not reult in the amplifier making much power.
Positive on sub to Positive on amp.
Negative on sub to Negative on amp.
This is your only possibility.
Adding a second sub in the same fashion will result in a 2 ohm load, and your amplifier will run at its rated potential.

With RCA cables. Just plug into the preamp outputs on the back that are labeled for "subwoofer" and run them to your amp. In your on-screen EQ, you'll have a separate adjustment for the sub (which adjusts that set of preouts, without affecting the tone in the rest of the speakers).
You either have a short, or the speakers are too powerfull for it, or the most likely problem is that your fuse is like 15 amps, but the amp is like 20 amps, so check the amps and if they are near 13 or higher, put in a higher rated fuse. :)
Well make sure you have enough power wire, remote wire, RCA's make sure they are long enough as well. Now depending on wattage the amp can kick out determins on the power wire size. Run a wire bout a foot from the battery + terminal and add a in-line fuse (once again depends on the power of the amp) now run the rest of the power wire to the back. (along with the remote wire and RCA's) Now hook up your RCA's on the sub output, (If no sub output hook up to the rear) this will connect to your amp RCA's input. Now for the remote wire, wire it up to the BLUE remote wire or power intena, this will go to your remote terminal on the amp. from thier all thats left is your speaker... Hope this was helpful
The amp is rated to run a 2 ohm load on each channel. To do this, connect the voice coils of one sub in parallel (tie both "+" on the sub to each other and both "-" on the sub to each other), then connect that sub to one channel of the amp. Repeat this process for the other sub and connect it to the other channel on the amp. The subs will be in stereo and the amp will be outputting it's maximum power.
