Yates Posted June 4, 2013 Author Report Share Posted June 4, 2013 Wait... Are you saying you wanna run one wiring for daily and one for comps? no Link to comment Share on other sites More sharing options...
MrSkippyJ Posted June 4, 2013 Report Share Posted June 4, 2013 then you aren't at .7 you are at .5 or 2 plus what Hugh said. the 2 ohms is what the specs say 0.7 ohms is what I measured don't go by what you measured. you have 2 ohm voice coils, your options are .5 and 2 (and 8 I suppose if you wanted it) F150: Stock 2019 Harley Road Glide: Amp: TM400Xad - 4 channel 400 watt Processor: DSR1 Fairing (Front) 6.5s -MMats PA601cx Lid (Rear) 6x9s - TMS69 Link to comment Share on other sites More sharing options...
Hugh G. Rection Posted June 4, 2013 Report Share Posted June 4, 2013 Wait... Are you saying you wanna run one wiring for daily and one for comps? no, what he is saying is that he is wired at an impedance below what his amplifier is rated for, and is hoping for his impedance rise to bring the load back into an operable range for the amplifier. the problem with this is that it doesnt change the nominal load as well. this is why so many spl competitors use impedance coils between the amps and subs.

will77530 Posted June 4, 2013 Report Share Posted June 4, 2013 you have cheap gear you shouldnt even try and drop below 1 ohm, and obviously you dont know how box rise works so you shouldnt try and count on it to keep your equipment safe Link to comment Share on other sites More sharing options...
k3n12ock Posted June 4, 2013 Report Share Posted June 4, 2013 Only 150a of fusing for a "3200" watt rms amp? You'll be lucky to get around 10.7 00 @ 1 ohm if you can keep your electrical up. Anyways, 0.7 might be ok I personally wouldn't. 05 xB - (2) EVIL 18s - (2) BC3500s - NO WALL Channel 1: http://www.youtube.com/k3n12ock Channel 2: http://www.youtube.com/MrK3n12ock2 Link to comment Share on other sites More sharing options...
SnowDrifter Posted June 4, 2013 Report Share Posted June 4, 2013 I want to go to competitions and have a daily driver my amp is a SPL FX1-5500 its 1 ohm stable my subs are two blaupunt vpw 460 18" 1800 watts rms each dvc at 2 ohms per coil in parallel they are 0.7 0.8 ohms I would only use this for completions same Hz round 45Hz havent tested where my amp or subs peak yet but I was wondering if I could use the box rise to my advantage is this safe I have heard of this amp being run at 0.7 ohms but I want to make sure my amp and the rest of my equipment is safe thank you I will upgrade amps later after my alternator upgrade If this is a burp box pull out the clamp meter and start testing.

Using a DMM helps verify that you have everything wired correctly and have quality connections by measuring the resistance. I am confused by your definition of impedance though.

Measuring with a dmm with give you what the DC impedance load is. That is not the same a the nominal impedance of what the speaker is tho. It'll be somewhat close but it is not the actual impedance. Go buy what the speaker says on it for it's impedance. With the equipment you have (and don't have yet needed for a stable voltage supply, unless your alternator puts out a good 150 amps already) I wouldn't run it below 1 ohm.
