osamio Posted December 24, 2010 Report Share Posted December 24, 2010 I have a Soundstream DTR 1700 watt amp, and two 400RMS pioneer subs. I'm planning to upgrade the subs soon, but in the mean time, I want to make use of this amp.. So the question is, Is there a process or method I can use to tune the gain so I don't exceed 800 watts? Or, is there any semi-accurate way to estimate the power the amp is putting out real time? obviously without an oscope or anything like that. My plan was to just mess with the gain and listen for clipping, or maybe even just eyeball about where to set it. I'd prefer a better method...Is there a proper way to do this? 2009 Cobalt LT Pioneer Headunit 2x Pioneer 6 1/2 (stock amp) 2x Pioneer 1" tweeters (stock amp) 2x Pioneer 6x9 (stock amp 4x Pioneer 6 1/2 Pioneer GM-6400F Soundstream DTR 1700 R.I.P 2x Champion series PRO 12" subs 0 AWG Big 3, Stinger SP1700 battery To come: New or repaired DTR!!

I'd prefer a better method...Is there a proper way to do this? clamp meter. it will tell you your final ohm load (freq dependent). do the math with your final ohm load on the freq you first tuned your amp with (if you tuned it at all) and that is prolly the easiest quickest way to be ~800 watts. (just around that tuning freq) edit:whoops clamp meter tells you amperage and sometimes voltage too.it doesnt tell you ohm load you gotta do math for that. I don't fuck around.

Carroot1 Posted December 24, 2010 Report Share Posted December 24, 2010 ya... clamp meters are expensive.... if it were me id just keep the gain low and make sure the subs are getting full unclipped power. but thats just me Link to comment Share on other sites More sharing options...
TeamHT Posted December 24, 2010 Report Share Posted December 24, 2010 what are the sub voicecoil configurations? Tell me...does this smell like chloroform to you? Link to comment Share on other sites More sharing options...
osamio Posted December 24, 2010 Author Report Share Posted December 24, 2010 what are the sub voicecoil configurations? 2 DVC 4ohm subs, wired to 1 ohm. I know i could wire it to 4 ohm, but i'm not seeing any specs for a 4ohm load for the dtr 1700. 2009 Cobalt LT Pioneer Headunit 2x Pioneer 6 1/2 (stock amp) 2x Pioneer 1" tweeters (stock amp) 2x Pioneer 6x9 (stock amp 4x Pioneer 6 1/2 Pioneer GM-6400F Soundstream DTR 1700 R.I.P 2x Champion series PRO 12" subs 0 AWG Big 3, Stinger SP1700 battery To come: New or repaired DTR!!

ISO Posted December 24, 2010 Report Share Posted December 24, 2010 Assuming your final load to the amp is one ohm, you would be better off changing your configuration to a higher ohm load like 4 or even 8 ohms. Expect to get around 500 watts at 4 ohms and 250 to 300 watts at 8 ohms. Isobaric - Refers to the practice of coupling two drivers together to make them act as one.

I wasn't necessarily worried so much about damaging the amp, as i was about only getting 500 watts out of it at 4 ohm... I understand it's the safe way to go, but it kills me knowing that I have a 1700W amp only putting out 4-500W, when i could mess with the gain at 1 ohm to get it around 1000W (hopefully without going over that and blowing my subs) 2009 Cobalt LT Pioneer Headunit 2x Pioneer 6 1/2 (stock amp) 2x Pioneer 1" tweeters (stock amp) 2x Pioneer 6x9 (stock amp 4x Pioneer 6 1/2 Pioneer GM-6400F Soundstream DTR 1700 R.I.P 2x Champion series PRO 12" subs 0 AWG Big 3, Stinger SP1700 battery To come: New or repaired DTR!!

TeamHT Posted December 24, 2010 Report Share Posted December 24, 2010 exactly what i would reccomend to just be done with it. wire to 4 ohms and call it a day. Tell me...does this smell like chloroform to you? Link to comment Share on other sites More sharing options...
ISO Posted December 24, 2010 Report Share Posted December 24, 2010 What good is useing all that power when there shouldn't be any positive gains from doing so? The woofers are only going to get so loud, period. Isobaric - Refers to the practice of coupling two drivers together to make them act as one.
