hhaudio Posted March 25, 2010 Report Share Posted March 25, 2010 So I threw my Hifonics 12's in a ported box, and I smell burnt/burning coil all the time now. Unless I turn it down to the point they aren't moving any air. Burned CDs, radio, bought CDs... no matter what I smell coil. They are still bumping and no change in resistance. Any ideas???

hhaudio Posted March 25, 2010 Author Report Share Posted March 25, 2010 Its the Massive Audio Nano Block N2 (800w RMS). Gain I believe is below half now, I was turning it down as I was driving. Box is tuned to around 32hz. about 1.5 cubes per sub with a 2in pvc port for each. Thanks Quote Link to comment Share on other sites More sharing options...

hhaudio Posted March 25, 2010 Author Report Share Posted March 25, 2010 just barely negative on bass. Its stock, i'm thinking maybe a gain setting on the hi-lo converter. Quote Link to comment Share on other sites More sharing options...
kmalinich Posted March 25, 2010 Report Share Posted March 25, 2010 for one, stock HUs almost always have a horrible output curve... no flat response at all out of the speaker leads...plus your "bass" level is negative... the stock EQ in the HU doesn't ever have a smooth slope to change the frequency levels... add that to a line output converter... that degrades the quality of the already crappy signal even more... especially ones with adjustable levels. you understand that you may have set the gains correctly at one frequency but they could be totally jacked up at another? and that frequency could be clipping the shit out of the amp. i'd recommend a head unit with good 4v RCA preamp outputs, and a good set of RCAs. i've personally never had problems with Stinger and Knu RCAs... but that's just me. get a decent aftermarket HU, run good RCAs, set the gain again, call it a day. you'll notice a huge improvement over stock audio quality... and i assume you're running the bass down on your HU because at high volume it over powers your speakers in your car? A decent HU has a high pass filter on it... that does exactly the opposite of what a low pass filter does... it takes the bass below a certain freqency (usually 80Hz or 120Hz) out of the speaker's signal. Just my $.02 Quote Link to comment Share on other sites More sharing options...
hhaudio Posted March 25, 2010 Author Report Share Posted March 25, 2010 Well I was holding off on the aftermarket headunit. I was going for a sleeper look. Guess I'll start looking for a headunit. I threw a Audiobahn 15" in and there wasnt any smell though? That's why I was confused. Any ideas on how to set the gain on the Hi-Lo converter for the time being? Thanks Again guys Quote Link to comment Share on other sites More sharing options...

Thanks Again guys Just to take a stab... I'd say make the Hi-Lo converter "gain" at like 75%.. same thing with the deck up front.. leave the EQ flat or off... then set the gains with a DMM. And I totally understand the sleeper look. You really want a sleeper look.. get a 3.5mm - RCA adapter.. use a Walkman cassette player as your head unit......lolol Quote Link to comment Share on other sites More sharing options...
