mttornquist Posted June 28, 2012 Report Share Posted June 28, 2012 Alright so I just picked up an Audison LRx 4.300 and have a quick question about bridging it. It is rated for 220 rms @ 4 ohms bridged and isn't stable below 4 ohms when bridged. I would like to run it in 3 channel mode with my front end off the first 2 channels and my sub off the bridged channel. The sub I am looking at is an AA assassin. The problem is that the assassin only comes in a d4 coil configuration. So I am wondering if I wire the sub down to 2 ohms then expect to see at least 1.5 ohm box rise this brings my final ohm load to 3.5-4 ohms that the amp actually sees. Does this make sense and will it work without risking the amp? Thanks! Matt Quote My Build Log: http://www.stevemead...lmost-complete/ Link to comment Share on other sites More sharing options...
bkolfo4 Posted June 28, 2012 Report Share Posted June 28, 2012 No, you cannot use that logic. At one time, AA had the assassin in a single 4 ohm coil. PM me your zip and I can see if any are available and get you a price.

MrSkippyJ Posted June 28, 2012 Report Share Posted June 28, 2012 why not just run it un-bridged?

412 CVX Posted June 28, 2012 Report Share Posted June 28, 2012 You cannot rely on impedance rise. it can happen because of a number of factors, but it's not something you can really calculate and predict. you can't rely on impedance rise to save your amp. if for some reason you don't have the rise you thought you would, you could potentially blow your amp. plus, there is no rise when the sub is at rest, so your amp will probably go into protect because of the lower ohm load. overall just not something to be relied on.

My temp system build log More box buildssome cars do over 170db with one sub, so clearly my two 12"s can do that in my car, with my knowledge too! look out bitches! I'm with captain stupid.

Ddub847 Posted June 28, 2012 Report Share Posted June 28, 2012 do they make dual 2s? cuz u can run 2 ohms per channel Quote Link to comment Share on other sites More sharing options...
412 CVX Posted June 28, 2012 Report Share Posted June 28, 2012 why not just run it un-bridged? i didn't think of that... that might work too Quote Just say no to Ground Pounder Customs.

Ddub847 Posted June 28, 2012 Report Share Posted June 28, 2012 running it unbridged will yield less wattz Quote Link to comment Share on other sites More sharing options...
MrSkippyJ Posted June 28, 2012 Report Share Posted June 28, 2012 running it unbridged will yield less wattz Running it below rated will yield zero when the amp fries.
