Zade08 Posted January 18, 2009 Report Share Posted January 18, 2009 Ok now that your done testing it you can mail my 3000d back to me. Ill PM you the return address. lol. Nice job man. Good to get a comparison on a TL. Quote Vehicle: 2001 Ford Escape Head Unit: Kenwood Kdc-x592 All out for a rebuild. New shit coming in the next 30 days.

Derrick824 Posted January 18, 2009 Author Report Share Posted January 18, 2009 Its still seems like they need more signal. No doubt my overall #s were down & I'm not 100% on why but for now I'm just gonna blame it on the freezing weather. Everything was done identically though so the comparative #s are legit. IMO the saz-1500d and saz-2000d power this stock sub right in it's sweet spot. I would typically expect a lil more gain going up to the saz-3000d but at that power level (more than twice rms) I believe power compression was starting to come into play. Also since the saz-3000d was tested last, the sun was setting and the temp had dropped a bit during that one. Quote Link to comment Share on other sites More sharing options...

Nice job on comparing SPL Your test results show a strong difference between amplifiers IMO It had more to do with electrical losses caused from the higher amperage draw of the larger amplifiers. Keep in mind every time you add power your reactive changes and every amp is usually going to be the strongest at a certain resistance after reactive (meaning a higher impedance is not always a bad thing). After reactive I have seen several amps be the strongest around 1.7-2 ohms. I remember Skip01 on another forum did a direct swap with a 500.1 and a 200.1 and there was only tenths that separated the two amplifiers (like .4db)...made perfect sense to me for one mostly due to electrical. Clamp these amps sometime for power and do a reactive load test. I am going to with a 1500D and a 3000D sometime this week.

bigbodylexus Posted January 19, 2009 Report Share Posted January 19, 2009 (edited) I know that if not one this site there is a test where ibanender (Sean B.) tested (I think both the 1500D and the 3000D) he did 14-16 volts and Sundown amps are amazing.

Derrick824 Posted January 19, 2009 Author Report Share Posted January 19, 2009 I got some more testing done today since the weather was a bit better. Temperature was in the upper 40*s. Everything else was identical to the previous testing on Saturday. saz-1500d saz-2000d saz-3000d Much better scores today. Even though I didn't get to test the saz-1000d I think it's a safe guess to say that it would also be somewhere between 0.9-1.1db louder hitting around 147.5db.

Nightshade Posted January 19, 2009 Report Share Posted January 19, 2009 One reason I think that your scores were up today over the other day is due to the batteries being able to produce more amperage at a higher temperature. Not to mention that you also said that the temperature overall probably had an effect on the score. I still have yet to determine what a lower temperature does to the spl and haven't had enough chances to test it. Other than it affecting the batteries and maybe the equiptment some, and definately the frequency it may also have something to do with the denser/less dense air affecting spl.
