kickass audio Posted October 12, 2011 Report Share Posted October 12, 2011 dont get an o-scope, a dd-1 is cheaper and more accurate. I would get a dd-1 if i didnt have my scope but im perfectly fine with how mine are set with the scope. I havent done anything wrong with my system other than popping off the dustcap on my smd but i glued that back on and its not moving at all. lol. I learned that whole under powering thing with my old solox sub i had. I fed it 1400w rms at 4 ohms and it barely got it moving and it was far from being loud but that damn thing got hotter than hell and smelled a ton. I eventually wound up burning the coil on it for good and it quit on me. I always recommend to save your time and money and do it right the first time. Trust me, i learned this the hard way. I blew well over half the cost of my current system blowing up subs, amps, burning wire, etc because i couldnt afford the good stuff at the time and quite honestly didnt know crap about it then like i do now so it made me waste a damn hefty amount of money on things im just throwing out to the curb. Its like i tell everyone i help on here, take my advice because i have learned a lot of good things from the expensive mistakes i have made with my system and a ton of other things i work on.

andale927 Posted October 12, 2011 Author Report Share Posted October 12, 2011 (edited) I am actually majoring in computer engineering and my dad is an electronic engineering professor so I can borrow an oscilloscope from the lab xD. One more question which is actually unrelated to my original thread but I don't think its worth creating another one. I have a 08 Nissan sentra se-r spec v and it had a "premium" rockford fosgate system. I would replace it with my own head-unit but that would disable the trip computer on my car. So I was wondering if I could use a high level to line level converter to give a signal to my amp. My concern about this is sound quality. Do these noticeably degrade the sound quality? Also the stock rockford amp puts out 100w to each rear channel which is what I would use for the sub, but all line level converters I have found say they can only handle 50w Edited October 12, 2011 by andale927 Quote Link to comment Share on other sites More sharing options...
Torres Posted October 12, 2011 Report Share Posted October 12, 2011 i read over on CA.com that if the sub is able to take at least 4 times the power that the amp can put out (before clipping), no matter how bad you clip it, it won't kill the sub. just food for thought. does that mean you should clip it anyways? no no no no Quote Link to comment Share on other sites More sharing options...

Some of you may remember FordRedneck302 (I think that was his name?) He threw a small Sony Xplod amp with gains and bass boost wide open on a pretty beefy sub (don't remember the exact model). He said the sub got warm but didn't get smelly. If the coil on the woofer is designed to handle a certain high wattage of AC power, it can usually handle some DC power without totally frying. Clipping is still bad, but it's definitely possible to send a square wave at a voice coil and have it survive if it's a strong enough coil and not too much power. Quote wtf is lolcats? I'd def get a fat hooker if i had to resort to that kinda thing. I feel like they'd be grateful and work harder. Also its more bang for my buck, more real estate for my dollar if you catch my drift. its like the Costco of streetwalkers. I was hoping for 150 . I was hoping she would let me put it in her butt Link to comment Share on other sites More sharing options...
kickass audio Posted October 12, 2011 Report Share Posted October 12, 2011 You can get a high to low converter but most ones i have found are crap. I would get one that is also a sound processor too. My 3sixty.2 has the high level input and outputs rca's and i used it playing around with my home theater system in my room and it sounded great through it. I helped another guy on here with a high/low converter which would clip at any level he set it at but he got a high/low converter that was also a soundprocessor/eq and it worked great for him. His dd-1 didnt find any distortion till he turned up the gain where his old high/low converter had distortion at all volume levels. If you really want a clear sounding system with a ton of great control i always recommend something like the rockford fosgate 3sixty.2 (and soon enough the .3) as they are great tools to have when you install a system whether keeping the headunit stock or aftermarket.

You can still damage it pretty good though.
