Jordan Thurston Posted April 1, 2015 Author Report Share Posted April 1, 2015 The subs share the same airspace so I do need to make sure my gains are matched properly what's the best way to do that ? Link to comment Share on other sites More sharing options...

Gregory Brissitt Posted April 1, 2015 Report Share Posted April 1, 2015 If the box has enough port area will probably do well, other than that you may want to learn how to gain match more so if the box is common chamber, could u explain how does one do this , gain match etc. Link to comment Share on other sites More sharing options...
Triticum Agricolam Posted April 1, 2015 Report Share Posted April 1, 2015 Both gains were about half way just subs couldn't handle the extra power.... Unfortunately the position of the gain knobs is meaningless. You can be putting out a clipped signal with the gain turned all the way down if the input voltage is high enough. Probably 90% of the time someone burns up a sub is because they are clipping. When you go to setup your new subs I strongly recommend you learn to set your gains the proper way or find someone who can. This will be extra important since you will be running two subs.

Jordan Thurston Posted April 1, 2015 Author Report Share Posted April 1, 2015 I don't think it was clipping but could be wrong the sub is only rated at 500 rms and I'm probably at least putting 800 to it I'm guessing that's why it blew but it very well could have been getting a clipped signal. When I get the new subs I will make sure I have it all set correctly. Link to comment Share on other sites More sharing options...

I love my mini ossciloscope (DSO Nano V3) for setting my gains but you could use a voltimeter and some math. Just don't try to set the amp to what it says it'll put out. 2001 Civic LX SedanPioneer DEH-7500HD Big 3 in 1/0 Knu CCARockford P500-4RF Punch P165-S in doorsRF Punch P165 in rear deckFront doors deadened with DamplifierNextSQ's new HDS208 8" in a T-line whenever it FINALLY COMES OUT I CAN FINALLY AFFORD IT Bend over and I'll show ya. how is it 2 days work? half a day at most, i may be an idiot, but im not an idiot.

When I get the new subs I will make sure I have it all set correctly. What makes you think you weren't clipping? Without the proper equipment its very hard to tell. The fact that you burned up your sub leads me to believe you were clipping. Its pretty hard to burn up a sub on music with a clean signal. Let this be a lesson to you. Ok so what all do I need to set my gains just a volt meter or do I need something else to ? I love my mini ossciloscope (DSO Nano V3) for setting my gains but you could use a voltimeter and some math. Just don't try to set the amp to what it says it'll put out. I also have a DSO Nano (mine is v1) and it works very well for the price, especially with the BenF firmware. Unfortunately you cannot just use a voltmeter and some math to set your gains. The reason is a voltmeter can't tell if you are getting a clipped signal and no amp is going to put out exactly what it is rated to. Better built amps will put out more than rated, so if you just use math and a DMM you won't hurt anything but you will be leaving some performance on the table. Lower quality amps often put out less than rated (sometimes MUCH less) so using math and a DMM you are going to clip the shit out of your subs. The correct way to set gains is with either an o-scope (like the DSO Nano) or a DD-1. There really aren't any exceptions to this and any other way is just going to be a guess.

Jordan Thurston Posted April 1, 2015 Author Report Share Posted April 1, 2015 Ok so if I put twice the power to the subs with a clean signal they more than likely won't blow ? They were fine for over a year on the alpine mrp1000 amp never had an issue can I get something that will detect clipping or is an oscilloscope cheaper than the tool that detects clipping ?
