Posted November 21, 200915 yr Unfortunately, the sundown 3000w install was whack because the head unit's preouts were going crazy so the amp couldnt be turned up high enough for an accurate comparison.I will post spec of the amp anyway but shouldnt be compared 100% accurately because the volume level wasn't the same as the other 2.Sundown 3000d-Voltage - 11.8vCurrent Pull - 122AWattage pull - 1440wVoltage Out - 18.6vCurrent Out - 64.6AWattage Out - 1202wActual Resistance - 3.47 OhmsEfficiency - 83.5%(Test not fair)Powerbass 3000D-Voltage - 12.15vCurrent Pull - 119AWattage Pull - 1446wVoltage Out - 62vCurrent Out - 19.7AWattage Out - 1221wActual Resistance - 3.15 OhmsEfficiency - 84.4%Audiopipe AP30001D-Voltage - 11.8vCurrent Pull - 170AWattage Pull - 2006wVoltage Out - 92vCurrent Out - 18.5AWattage Out - 1702wActual Resistance - 4.97 OhmsEfficiency - 84.8%Notice how the Audiopipe is more efficient than the powerbass with less voltage, does more power at a higher ohm load and is cheaper.
November 21, 200915 yr Damn nice comparison..... sucks that screwed up on the Sundown though....... is that AP really mono? every time I find specs on them I cant decipher the stupid information, always sounds like it's 2 channel... anyways, nice work man!
November 21, 200915 yr its a 2 channel bridged amp. two 1500d amps inside it. I don't understand how hard it is to flip the amp over and get the actual wiring diagram for the amp on the back of it. I'll post up a picture of it.
November 21, 200915 yr Author it is a 2 channel class d amp.1500w x 2 at 1 ohm on each channel or 3000w @ 2 ohms bridged.
November 21, 200915 yr good comparison since these are some of the more well known (common) 3k watt amps
November 21, 200915 yr it is a 2 channel class d amp.1500w x 2 at 1 ohm on each channel or 3000w @ 2 ohms bridged.its a 2 channel bridged amp. two 1500d amps inside it. I don't understand how hard it is to flip the amp over and get the actual wiring diagram for the amp on the back of it. I'll post up a picture of it.thanks guys.... every time I decide to look this thing up the online dealers can't get the info straight for nothin'...... it looks good but I still think I'm going to go with a SAZ 2000 or 3000 for my Q's, but this comparison sure does show that the cheaper products aren't doing bad in their own right....
November 22, 200915 yr Thank you very much for these informations. We must remember power is important, but reliability too!I am not saying AP and others are not good!
November 22, 200915 yr Hehe, I know someone with an audiopipe 3000 that switched the power and ground twice and it didn't die. The same amp was ran for 5 months. It was only screwed down to the floor once for a competition with one screw. During a testing day, the amp was just placed on the top of the box for burps with a notepad between the amp and the top of the box. Reliability...
November 22, 200915 yr it is a 2 channel class d amp.1500w x 2 at 1 ohm on each channel or 3000w @ 2 ohms bridged.is the powerbass a 2ch bridged also? does it do its power at 1 ohm or 2?if its a true mono that does its rated power at 1 ohm then that would be a good reason why the audiopipe does more at a higher ohm load.
November 22, 200915 yr Author powerbass is dual channel but internally bridged so actually just single channel.While it is true that the audiopipe does it's max at 2ohms rather than 1 ohm, u must also consider this-When we tested these 3 amps, the sundown AND powerbass had a nominal 1 ohm load(0.8DCR). The audiopipe had a nominal 2 ohm load(1.6ohms). so the test is fair between those 2 amps.I have seen that the higher amounts of power a sub is given(as long as it's not into power compression or excessive heat build up), the lower the impedance rise is.So by saying that, it's not uncommon to use a 2kw amp and have a rise from 0.7 to 2.3 ohms then turn right around and hookup a 4kw amp and rise from 0.7 to 1.8ohms...
November 22, 200915 yr 3000 watts. Man, give me 15 mins. I am going to take a picture and post it. I keep forgetting.
November 22, 200915 yr Not stealing your thread...but... I'll add some extra data from My old test from last year or whenever...Amp_____________V*A produced______V*A Consumed__Output_______Input__________eff____Calculated ohmSundown SAZ3000D_77.0v 31.0A____ 13.10v 219.5A_ 2387_________2875___________83%____2.48ohm Massive P-3000D____91.0v 37.8A____ 12.00v 360.0A_3440_________4320___________79.6%___2.41ohmAnd the sundown wired down to lower ohms... .8 restingSundown SAZ3000D_72.0v 48.0A____ 12.40v 378.0A_3456_________4687___________73.7%____1.5ohm***the p3000 should have been tested at this ohm... I run mine daily at a 1 ohm load.. I may test them later..The P3000 uses the same board but has different componets/build than the audiopipe.. looks close to the same kind of numbers..

November 22, 200915 yr My Preouts on my HU unit sucks, even with a new ground so testing the Sundown wasnt very informative at all, Even after I redid the grounds. I'll redo them again today and see if it still happens. No more Pioneers for me Edited November 22, 200915 yr by Enellz

November 22, 200915 yr I got a friend with a hifonics Bxi1608 amp. I'll try to get that to a meet up to get it tested.
November 22, 200915 yr Author we were talkin about testin an AQ3500D and postin it up here but the way how mine are mounted.. it's tricky to get any readings off of it. If i do get a test off of it, i'll sure post it up here.

If i do get a test off of it, i'll sure post it up here.Is it also tricky to take it out of its mounting location? Im thinking just take it out your car and measure it in someone else's.
November 22, 200915 yr He has two batteries mounted on a layer above the amps. It would be hard to even try to steal them lol.
November 23, 200915 yr sean, your aq 3500 vs my sundown 3500Once I get my electrical set we can do a direct swap in my truck since it would be easier to get to
November 23, 200915 yr Author nope, can't get my amp out of the car... Besides if i could easily, i could meter it easily.That amp comparison test was already done anyway a while back. I don't know efficiency outcome but i do know the Sundown put out more power which i knew it would anyways.
