your wiring is wrong.. positive to positive.. negitive to negitive.. then opposite sides to the amp..

that should bring the sub the 1-ohm.. as long as the amp is stable at that impendence then you should be ok.. as far as the sub bumping without the rca pluged in.. that might be an output problem on the amp then.. but hard to tell..

that is the easiest way for me to show you. check all your wiring making sure - is to - and + is to +. if its all hooked up correctly then you may have a defective or burned amp.

your wiring is right for a 4 ohm load. the thumping could be a ground issue or voltage issue.

the amp has to be fried! i tried wiring it atleast 10 different ways and all it does is go to protect and the sub goes thump,thump,thump........... well you get the picture. i also noticed a kinda electric humming comming from inside the amp right behind the Power block????????? i'm no expert but i think they sent me a bad amp or it got damaged in transit. hooked the sub up to the back 2 channels on my 4 channel amp bridged at 4ohms and it works fine. oh well atlest i'll get to break it in nice and easy. 300 watts rms. lol.

The way he said he hooked it up would be acceptable also!
You described a parallel connection, he described a series connection.

It's like connecting 2 batteries together.
Say you have 2 Car batteries (12v) and you connect them in parallel, you would still have 12 volts, just more amperage. If you connect the same 2 batteries in series, you would have 24 volts without an increase in amperage.

Both types of connections are acceptable methods of wiring, it just depends on your desired result.

In his case, if he wasn't sure if the amp could handle a 1 ohm load, the the safe bet would to be wiring in series.

called vm innovations today. i have to say that they have some of the best customer service i have ever dealt with. no questions asked. i told him what happened he said send the amp back and when they recieve it they will ship the new one. sounds easy. the only thing thats kinda sucks is that i have to pay for the shipment back to nebraska. oh well if they send the new one as easly as they said it will be worth it.
