purplesyrup Posted July 28, 2013 Author Report Posted July 28, 2013 OK, thanks for the info, I was a bottle and a half deep in rum and really confused about these, lol MMATS told him this, These are not meant for daily unless you have a huge electrical system, (which is what I am doing to it) They said there is no "Low Voltage" protect, which is why both amps blew up not long ago and he has these new ones now. They said bad voltage drop kills these fast. But yea, any other info anyone knows/ finds let me know, I have only found one site where people briefly talk about them, with real tech info on these. He bought my other 2 NSB 170's that I had left, so 2 6,000 amp batteries, 170 AH each, Right now he does not have a HO Alt, im contacting mechman about what options he has, the stock alt is 160 amps, So we will be running 2 Optima 55 AH yellowtops under the hood (brand new he already had them) and those 2 gigantic bats in the back Think that is enough electrical to hold the voltage up on these until he later on gets a mechman alt? I am thinking those 2 huge batts in combo with the 2 other yellowtops will have no problem holding the voltage past 12.5, opinions please. (I run 2 of these giant batts and ran my nendo bc3500 car off near full tilt for 5 hours at a car show voltage got down to 12.7, they rest at 13.1)
knowledge Posted July 28, 2013 Report Posted July 28, 2013 mmats amps are pretty strong REFF'SMy linkEBAYhttp://feedback.ebay...ck&myworld=trueI love car audio so much because I will never be done. I can never win, and I will never get it finished or perfect. It always has me coming back for more, I can never get my fill of it, but I get what I need.
Cashdollar2009 Posted July 28, 2013 Report Posted July 28, 2013 I replied to your Facebook post. But I will reply here. The 4000.1d's are supposed to be "Team Only" amplifiers. They are the 3000.1d's with no protection circuitry. My buddy has had his down to 11.8V on burps with no issue. You CANNOT set the gains with an o-scope WITHOUT the subs connected. I would suggest wiring the subs up to set the gains then wire them back down for use. DO NOT use higher than 2.0V RCA input signal, it will fry a cap or two. They made it this way because "2.0V has yielded the best sq." This is through personal discussions with the owner of MMATS. Our shop is an authorized MMATS dealer. (Ergo Audio in Edinboro Pennsylvania) They have a smaller footprint than your average 2k but do every bit of rated power. Just make sure to follow those two guidelines I listed above and you will ben alright. On 6/30/2011 at 1:11 AM, 'Ray' said: Acoustical energy is free. Electrical energy is not.
purplesyrup Posted July 28, 2013 Author Report Posted July 28, 2013 Shit so if his HU has a 4 volt out it needs to be changed?
CJ18 Posted July 28, 2013 Report Posted July 28, 2013 No, that just means it can put out up to 4v. Check it with a 40hz tone with the eq settings and volume set where you would normally play and adjust from there.
purplesyrup Posted July 28, 2013 Author Report Posted July 28, 2013 Right on. Thanks for the help guys never had a team amp in my possession nor did I know how picky they could be
Alain Posted July 29, 2013 Report Posted July 29, 2013 I have a dc 270 xp alt on my impreza with an d3400 up front an xp 3000 and a 2500 in the rear. I have the hd4000.5 on my btl n2s dual 2ohms tune @32hz (daily) and she plays them hard but gain have to be set according to electrical .
purplesyrup Posted July 29, 2013 Author Report Posted July 29, 2013 Ok so he has 2 optimas. 55 AH each and the nsb 170s are 170 AH. Each one is equal to 3 of those optimas so it will basically be like he has 8 of those optima batts. That should hold the voltage up pretty gooduntil an alt goes in.
81000D Posted July 29, 2013 Report Posted July 29, 2013 I wonder if you can set the gains with a dd-1 with the subs disconnected ?
