i was tuning my system today and my momo's tweeters smoked and my mids sound like *** now : ( Im wondering if anyone can help me figure out why they blew ? They were being powered by a sundown 100.2, and i think i set my gain accordinly ( first time setting gain for a 2 channel amp ) i used the equation sqrt(100x4ohm) and set the gain so that each channel was sending a voltage close to 20v. is that the right way to do it or do i add the channels up and set the gain to 40v? anyways i was playing some test tones ( 50-200hz sine sweep) ,(1 hz- 22khz sine sweep), etc and the drivers side stopped playing. Then both mids went out, and the tweeters smoked :crying: any ideas of what i did wrong ?

also wondering if i can get any suggestions on new speakers ? Price range for new comp speakers is about $250.......... i was looking at the Image Dynamics CTX65CS's and thought those might be a good choice. But i want some speakers that sound better than the momo's and have good midbass :D

Why.........test tones. IMO you should never run tones through your front stage with full power. My guess is they were 0db tones. Most music is equal to -6db IIRC.

yes they were 0db tones : ( however i dint have it turned up all the way........... i know i ****ed them up and am by no means very good at tuning my mids/highs. How do you guys tune your system ? this is my first system with comps........... im not very experienced in this part of car audio............ yet:D maybe some day lol

I sent you a PM with a couple suggestions for speakers which include the HSK165, but mainly the Morel Tempo 6s... As far as tuning options go, shoot me back a PM and I'll detail how I and many others do it with no problems :)

You could have just adjusted your gain by ear and you would avoided all these problems...
