Kranny Posted February 10, 2014 Author Report Share Posted February 10, 2014 To those guys testing the Alpine 148 and 149 units, I assume these are from the RCAs, any way to test what the internal amp clips at? same way you'd test the rca's. except just put the dmm probes on the speaker wires that are coming from the headunit harness.

LOL, guess I should have worded that a little better. Is there any way you guys could test the speaker wires to see where the internal amp clips at? I dont have an Oscope and my wife is thinking about buying me one of these 2 models for my birthday. Link to comment Share on other sites More sharing options...
ToNasty Posted February 11, 2014 Report Share Posted February 11, 2014 so the ampline 147, 148, and 149 should be the same? i have the 147 but not sure what it clips at i never go past 30 anyway ***Super Sellers List***http://www.stevemeadedesigns.com/board/topic/25829-super-sellers-buyers Link to comment Share on other sites More sharing options...

I would like to know if the speaker level outputs clip though. If I get one, I may need to run my mids off the deck for a while until I can afford to upgrade to a decent amp.

PaCiFiKbAllA Posted February 11, 2014 Report Share Posted February 11, 2014 JVC KD-AVX77 (my most recent upgrade woot! woot!)First of all, this deck has a shit ton of settings, of which I think I disabled all of them before I tuned my deck. I will go over it again tonight and post those results later.40/50 **UPDATE** After thoroughly going thru the manual and disabling all the who-ha, I retested and was able to get it up to 50/50! So, out of all my 5v preout headunits I've ever owned, ALL of them are clean and don' clip. =) 1 x Fi Audio SP4 V2 12" D2 Fully Loaded 1 x Wolfram W-4500.1 2 x XS Power D5100's 250A Singer Alternator 2.67 Cubes @ 29hz Link to comment Share on other sites More sharing options...

bassman619 Posted February 12, 2014 Report Share Posted February 12, 2014 I feel Iike everyone is going to have different opinions on this depending on how they are testing the headunit and what head unit it is. DD-1 Is going to have different results than an oscope. From what I heard the dd1 is better at seeing distortion than an oscope. Ive seen videos where multiple dd1s are seeing distortion before the oscope does. And ive also personally seen two different hus of the same make and model put out different results. Impossible? Not really...machines were created by man so they cant be perfect if man isnt perfect. Wierd right? All I know is that if youre trying to set gains without some type of device (oscope dd1 or other) then you are setting yourself up for failure and should just invest in buying a device to help you instead of buying new equipment once u burn what you have..unless youre one of those people who just buy new stuff every once in a while..in which case id assume you got enuff to buy the tools anyway. You need trunk space to get groceries and shit...bitches love groceries Link to comment Share on other sites More sharing options...
