I have a 1000 watt Sony Xplod 2/1 channel hooked up to two 12" pioneer subs TS-W301R and everything just quit... I've checked all the wires and fuses and the green light still comes on. I checked the subs with my home radio and they worked fine... What can I do to fix it?

You should definately bridge them. Firstly, lay the 2 speakers face down next to each other. Note the connections +- +-. The first + will go to the amplifier. The next terminal(-) will be connected to the next speaker(+). Take the last(-) and connect to amplifier. Please note that your amplifier has a bridge section which is normally the first + and the last- on the two channels. Connect your woofers on the bridge.
If your still getting a green light, it at least sounds like the amplifier portion may still be funcitonal. Perhaps your inputs are blown. If your comfortable with electronics, pop the cover, and try patching a signal directly to the amplifier stage. and of course check your source.
Most likely one of your subs are blown, or the Ohm's are too low for the ampliphier. Try hooking up one speaker at a time to the amp and see if it does the same thing. If it shuts off on one of the two speakers, that speaker is most likely blown.
asuming the 8s are 4ohms each; wire two in series and that gives you 8ohms then two more in series then you put those together in parallel and it gives you a 4ohm load. repeat with other four for the other side. you should then be able to bridge the sub
series; posative of one speaker to negative of other speaker and that doubles your ohms
parallel; posative to posative negative to negative and that cuts the ohms in half
If they have the same impedence (like 4 ohm) then you should be able to
run two different model number speakers as if they were the same model
number. There might be a slight difference in the way they sound,
but I would not expect it to be enough to be noticeable. Good
Almost all after market amps use 12v at very very low amperage to trigger the amp on. A temporary jumper from the battery plus terminal on the amp AFTER the battery and ground wires are attached should cause the amp to turn on. I would check to see if you have attached your speaker load correctly ESPECIALLY if you are bridging. Most of the blown amps that come into my shop are due to incorrect bridging loads from the speakers. Note that a 4ohm load bridged across both outputs of an amp will deliver a 2ohm load to each of the channels. When you parallel wire two 4ohm speakers together and then attached them to a bridged amp you will be putting a 1 (one) ohm load to each channel of the amp. Please don't make this mistake. It will fry your amp in about a month. Hope this helps. Good luck.
