I currently have two Rockford 12" HX2 subs (500W RMS each, 1000W Peak) running off of a Rockford 800a2 older 90s amp. From reading the documentation, I want to run them at 2-ohms to optimize the power from the amp to the subs. I have the subs wired properly (I think) for a 2-ohm load on their DVCs. I'm just confused about wiring the amp part.

I've tried a few different setups, and I'm not certain I have it done right. The most optimal way to wire it seems to be positive and negative from one of the channels to the subs in a series. If I take the negative from one channel and the positive from the other channel, and bridge it, the amp gets WAY too hot. Sounds great, but too hot. I believe this is a 1-ohm load and I don't want to run that on the amp. Can someone knowledgeable please provide me information for wiring this two-channel amp to these subs properly, at a two-ohm load? Thanks.

 
OK I just read the documentation again and I misplaced a couple things. Right now the speakers are wired at that diagrams (2) speaker (4) ohm load. It doesn't show a way to wire them for (2) ohms... does anyone think its safe to run this amp at 1-ohm? Rockford suggests not, there's proper air ventilation but the thing almost burns me when I touch it after twenty minutes. Maybe its because I have them wired wrong... so much to learn.

 
Woo, thanks for all the responses!

I got it, anyone care to tell me if I'm way off base? Ran both speakers in parallel from the two channels, speakers wired at 1-ohm each as per rockfords website. Technically, amps wired for four ohm, speakers wired for 1-ohm, pulling two ohm? Either way, the bottom drops and the amp gets just a little warm. //content.invisioncic.com/y282845/emoticons/clap.gif.178cba2c538c68e720c727fcb024b19c.gif
