rogue Posted February 10, 2012 Report Posted February 10, 2012 If you read the jl 1000/1 manual it specifically says the amp will produce less power at lower impedance levels than what is recommened. I second the 2.66 ohm load. its a no brainer anyways given the 1000/1 rips system. Its on page 10....reduces power in safe mode with loads under 1.5 ohms http://mediacdn.shopatron.com/media/mfg/9013/media_document/live_1/1000_1_MAN.pdf?1317780748 Quote BMW X5 Stealth Build w/ IPAD BMW 325i Rear Deck Digital Designs Build BMW 325i Car PC Touchscreen Bezel Build

Im thinking bout doing a 1000/1 per coil on a dual 1 ohm sub but was concerned of issues.

650rcode Posted February 10, 2012 Author Report Posted February 10, 2012 UPDATE: good news, the problem was in the wiring, i guess too much stress on the amp with the .67 ohm load, so i wired it in series/parallel like the diagram above to 2.66 ohms and all is good now. Given that each sub is only seeing a little more than 150 watts it sounds pretty good. he needs another amp for sure and he should be in business. thanks for all the help guys, much appreciated!

rogue Posted February 10, 2012 Report Posted February 10, 2012 Hmmmm. well I guess some 1000/1 will work at that impedance and others wont. Think i will play it safe in my install. there is no apparent gain from going below 1.5 ohms if ray is only clamping 940 at .67 Glad you figured it out.

Ray Posted February 10, 2012 Report Posted February 10, 2012 Out of the 3 cars i have here, it only works in my truck. Voltage protects in the other ones. Really needs a good batt bank to wire low.
