Syphlyn Posted July 27, 2014 Report Share Posted July 27, 2014 Hey guys, I bought a Sundown SAZ-2000D amp off caraudio classifieds from someone with over 30 excellent reviews and is apparently a former Sundown Rep (I think I saw it somewhere, I could be mistaken). The amp is 1 year old and is in perfect physical condition. It was packaged extremely well using newspaper and about 15 cloths. Box had no damage to it and there's no dings or anything from transport. Anyways I threw it in my truck today with intentions on setting the gain and throwing it on my Type Rs on a 2 ohm load. I then plugged my DD1 into the amp (Pos into speaker out and neg onto ground). I Was setting the amp with my HU on 30/35 volume, where it doesn't clip according to the DD1. I used the 40hz - 5db tone and I noticed while setting the gain the moment the distortion light appeared on my DD1 I could hear a faint buzzing noise coming from the amp. As soon as I backed off and the light went off and the buzzing disappeared. I then played my amp at my set my volume and it sounded great. To clarify I did disconnect my subs from the amp before using the DD1 and my truck was off. I should also mentioned I just used my 4 gauge wiring I have running through my truck for this test on two ohms/setting the gain quickly. I do have full 1/0 gauge OFC wiring for when I actually get my X12 subwoofer and have my box built. This test was to make sure it works after receiving the item. Also when I turn my truck off from the accessory position I hear a light pop while the amp turns off. Is this anything to be concerned about or is it normal in bigger amps. This is my first amp over 1k watts. Previously I had and still have an Alpine MRP-M1000. Thanks guys!

Kyblack76 Posted July 27, 2014 Report Share Posted July 27, 2014 Yes right at distortion, you may hear a buzz or hum.... that is a good indicator your doing it right.

ToNasty Posted July 27, 2014 Report Share Posted July 27, 2014 The amp is over a year old. The 2000d hasn't been made in a few years Quote ***Super Sellers List***http://www.stevemeadedesigns.com/board/topic/25829-super-sellers-buyers Link to comment Share on other sites More sharing options...
tacomaguy1 Posted July 27, 2014 Report Share Posted July 27, 2014 That's how I set the gains on my sub amps.... Might not be the pro way but it works for me Quote Team Flex Issues Link to comment Share on other sites More sharing options...
Syphlyn Posted July 27, 2014 Author Report Share Posted July 27, 2014 (edited) The amp is over a year old. The 2000d hasn't been made in a few years Yeap I'm aware it's 1-2 years old. He was a rep (I'm pretty sure I read it somewhere) and he used it for a year in his vehicle before upgrading. I should have mentioned it was used for a year. Yeah it's discontinued. It makes sense though if you have a 1500 and a 2500 there's really no point in a 2k.

Kyblack76 Posted July 27, 2014 Report Share Posted July 27, 2014 The buzz is perfectly normal RIGHT at clipping. Your fine. Quote SMD SUPER SELLER The Burban Build Blazer Build sold Acura trunk build sold Link to comment Share on other sites More sharing options...
Syphlyn Posted July 27, 2014 Author Report Share Posted July 27, 2014 (edited) The buzz is perfectly normal RIGHT at clipping. Your fine. How about the pop when I turn my key off? Is that normal too? Could it be from only using 4 gauge, mind you I was running it at 2 ohm which is apparently 1k watts. Edit: Yeap the DD1 showed clipping at the exact moment the buzzing started. Thanks man! Good to know was worried for a bit.

Kyblack76 Posted July 27, 2014 Report Share Posted July 27, 2014 The pop, is all on your end. Thats your turn on needing a lil delay. Where are you getting the turn on from? and yes,.. the buzz, as discussed here before, many times... is perfectly normal. My 10k did it along with 3 other amps. We actually joked if we could use just the BUZZ to set the gain.... Damore was in the discussion even. Dont worry about it. The POP, is on your end. Thats a very common problem with turn on.

The turn on? From my headunits remote wire. I spliced into it using my 16 gauges OFC wire. and ran it back to the amp. The pop only happens when turning OFF my power not on. Also running a second amp (PDX-F4) off the same run. So I have 1 remote run from my HU going to the 2000D and then from there a shorter 16 gauge wire from the 2000D to my PDX-F4. Should I be concerned and try to fix it even though I'm not sure how.

Karkov Posted July 27, 2014 Report Share Posted July 27, 2014 (edited) Add a relay for your remote wire, there is power going to amps even after vehicle is off (for a split second) Also, as said above that buzzing is normal at or above clipping on the DD-1. I run the same amps as Steve Meade and all 4 of mine do it. EDIT: In theory running 2 things off the remote is fine (IMO) but since you are having the issue just add a relay, if that doesn't work come on back and tell us. Also, even though you could use like 18+ gauge wire for remote maybe you could try using 14 ga. or something also. I noticed when using 18 ga. I have a hell of a time getting my RF amps to grab it, the input for remote is large on these amps so I could prolly run a larger wire. (not anything to do with your problem but meh) Edited July 27, 2014 by Karkov Quote 2007 Chevy Tahoe (SOLD) 12 ~ FI Audio X series 10" w/BP option 2 ~ DC Audio 5.0K @0.67 3 ~ DC Audio 5.0K @1.0 2 ~ PPI 3 way sets (not installed yet) 1 ~ RF T400-4, 1 ~ RF T600-2, 1 ~ RF T600-4 4 ~ CT Sounds 5.25" Strato comps (rear fill only) 1 ~ XS Power D4800 1 ~ XS Power D3400 8 ~ XS Power XP3000 160 stock alt, Mechman 370 Elite, 185 DC Power 320+ Sq.
