I just got a saz 1500d and am trying to get the gain set just right. With nothing hooked to it and at 27/35 volume, bass -2, sub -2 and with the gain set 1/2, my DMM reads 60.8 volts. This seems way too high but it does sound pretty good on my dd 3512 wired to 4 ohms. Only thing though, 60 volts would be equal to 3600 watts at 1 ohm. Am I doing something wrong or is this the baddest 1500 watt amp in the world?

Well I just got back from picking up this earthquake amp. In a little rough shape but it is a ph1000w 2 channel. Any input on this?

ok so im going to be using the Fi BTL 12" sub D2 in a 2.5 cu ft box ported to 34 hz. in the trunk of a chevy cavalier. i want to run in DB Drag so the power needs to be there when the car is off. so it will be at around 12-12.5 volts. the battery will be a Kinetic HC 2000 so my decision comes down to this. a brand new AQ3500 for 550$ or a refurbished SAZ-3000 with new heat sink and B-stock (not sure what that is) for 575$. i would like to know the pro and cons of each one. i know one uses a fan for cooling and one doesnt. is there an advantage to this? which one is more efficient at 1 ohm? which one will output more power at 12 volts? or any more things i should now a…

sooooo heres how the story goes. i got an amp a while ago, the crunch gp 2500d, and then i bought some subs, like the aq sdc 2.5s, but take a little more power (called TF X's if anyone is interested) both dual 4's wired down to 1 ohm at the amp. anyways, i'm underpowering them by a few hundred watts, and i'm looking for a replacement. in my searching i as offered an earthquake ph-d3 for a bit less than 300 rom a friend of mine, but i think he used to use it for spl comps a few years ago. anyways, the amp works great, and at 1 ohm does 3000 rms, so i figure if i'm easy with the gain i'll get the output i need, or i can match my current output at 4 ohms with 1300 rms. m…

ummm can you run a RF t1000.1db @ half ohm

so does the size or gauge mean anything with remote wire or is the standard size fine llike, does increasing te auge a lil help at all

Today is not a good day. i got my remote gain yesterday i installed it today.. also The plan was to finally have my subs back. i got my DC's back from rusty. and was happy to slap once again... i opened the box and one was broken:( i called rusty and he is so nice... but that's another story. i was hooking up one of the dcs to see if it works and i heard a hum it then everything turn off.. not the car but my amps and the music.... so i check the fuse in the front and its blown. i replace it and then my rf250.2 turns on. but not the merlin?? i took out the merlin and seen the fuses are blown.. so i replace them.... and then when i hooked it up again.. i heard the hum again…

last time i hooked it up the blue light indicator is on,but i was wondering why it does not power my re adio mx 12 sub.i have it wired in one ohm i can barely hear the sub pound. I called us amps and the guys said that iteh amp needs a 200 plus amp alternator and two batteries to power up the amp the right way.Is it true? He said that a stock alternator wont even power teh amp at all.IThanks for your help guys.

So in my electrical class my group and I are doing a project on MOSFET's and I will be bringing in some MOSFETS (blown and new) for some show and tell, then I wanted to bring in my amp (saz2000) and show that off but then I looked at the board and I was like umm maybe I should learn all the parts and how the amp works! so here is my amp's guts (i got the pic from another forum the saz2000 pre-sale one!) so here is what I understand (i hope i am not 100% wrong) on the far left and right sides those are the MOSFETS, the power supply are the 4 red coils, the caps are on the bottom center and top, the teal things I don't know (top center) the pre-amp is all that stuff at …

So last night on my way home from work I was listening to my stereo and all of a sudden the H.U. shuts off and then restarts(Alpine 9884). I installed the H.U. last year in November and never had a problem with it then about a month ago I put in a Sundown SAZ-1000D and a Fi 12" Q. Never had a problem with my H.U. turning off before last night. I dont know if the cold had anything to do with it. It was around 30 out and snowing. Today comming home from school it was listening to it seeing if it would shut off and it never did then comming to work a few hours later it started doing it again. I have yet to do the big 3 and my voltage drops pretty good. Im driving a 97 bla…

I am wondering what sized wire is sufficient to run from my amplifier to my subwoofer. It will be about 6 feet long and delivering approximately 1750-2000 watts rms.

I just got it off craigslist for a $100, its rated 150x1@4, 300x1@2 and 800x1@1. Are these underrated? I wanted to know because i plan to buy a Fi Q. thanks.

I was always told to go for the highest number, but i cant tell any difference in amps with high numbers verses those with low numbers?

This is from another thread.... Was looking for some clarification, or some words of assurance from Jacob. I personally love Sundown Products, and don't want people to be steered away by false information. I'm not saying that "smgreen20" is not legitimate, just asking for some official info. Thanks

I currently have a Pioneer DEH-7800MP and am very happy with it except for the fact that I would like a DVD player/flip screen. I'm trying to find something with 3 preouts, some crossover abilities, and fairly inexpensive. The head unit has to be single din and a flip screen because my dash would have be cut for a full din. The Clarion looks decent but I can't find much info on it other than really general stuff. Ebay, Crutchfield, and other online sites have it for around $350 shipped and that's the price range I'm looking for. I'm not sure if I will be happy with less crossover abilities but not sure if I really need them either. My current 4 channel is a JL 300/4 runni…

Hey everyone, I was at the USACI/Second Skin show this last weekend, and I won a couple SSA subs, the 12'' DCONs. Anywho, I wanted some input from you guys as to what I should use to power it. A guy I know that works for Diamond Audio suggested this: Diamond Audio D3 600.1 Someone else said that amp isn't going to push enough power. So, what do you guys think. Any suggestions?

I have a couple questions. First, I will tell you what I have. I have a ported box w/ 2 12's they are DB drive PLW12D4's and each sub has its own amp and the amps are Crunch Pzi 1500.1. I also have a yellow top battery under the hood, a 200 amp alternator, a kinetik 800 battery in the trunk, and a 3.0 farad cap. Ok now I am thinking about adding another 12" DB drive, a sundown 1500 amp, and a custom box which I am thinking of having it made to the specs of the subs and 32Hz. I have a 1997 Ford Thunderbird. Also I have about 36 inches for the face of the box to be so the box fits in the trunk. I am looking for SPL. I use the car as a driver but also take it to show…

The RXD2400 is here http://www.audiosavings.com/products/product-details.aspx?item_guid=9a264828-aec4-49a5-a358-7b5083208110 claims to be factory refurbished. And the BB2400.1 is here http://cgi.ebay.com/PLANET-AUDIO-BB2400-1-3000W-MONO-D-Car-Amplifier-Amp_W0QQitemZ350261934154QQcmdZViewItemQQptZCar_Amplifiers?hash=item518d3cf84a and claims to be new. Anyone have any input on this brand in general or these specific amps. I am looking to push a high powerd single 12 in a daily driver/ mild comp setup. TIA.

i am going to be powering an Audioque 4X90 and an Audioque 2200D, was wondering if the planned electrical upgrades would be sufficient enough. Kinetik HC1800 up front and another Kinetik HC1800 in the back Knukonceptz KonFused +/- Battery Terminals for both batteries 1/0 ga welder's cable for big 3 upgrade 1/0 ga welder's cable for power/ground run from front to back 1/0 ga welder's cable for 2200D 4 ga welder's cable for 4X90 Knukonceptz KonFUSED High Current In-Line Fuse Holders ran after second battery in rear, 3x 30A fuses for the 4X90 and 3x 100A fuses for the 2200D 8 ga wire for the subs 10 ga wire for the components haven't decided if i will need a h.o. alternator…

Seems a little pricey.... http://www.amazon.com/gp/product/B0016L37V6

My friend has this amplifier, and I've been looking on various websites, and everywhere says it does 1200 watts RMS into 2 ohms, anyone know if this is true? Because I can get this amplifier for very cheap, it has a problem though.... It doesn't turn off. As soon as we connected the negative wire, it turned on, remote wire wasn't even hooked into the amplifier yet. But anyways, does this thing really do 1200 watts RMS into 2 ohms?

Hey guys, i'm looking for 1/0 gauge wire for a big 3 upgrade. I was researching some wire and it seems that 1/0 is pretty damn expensive. I stumbled across this brand knukonceptz which was the cheapest, and i had to post something to get feedback, because i noticed in their description that their wires are made up of 90% aluminum and 10% copper. Now for an amplfier i wouldn't care, but i'm pretty sure for a big three upgrade i'm looking for least resistance, and that wire is basically all aluminum. I'm not trying to bash the company, but would you guys recommend this wire for a big three upgrade, or should i go off looking for something that has pure copper threading in i…

I am looking into buying a new 4 channel and have been looking into a couple models: the Zapco c2k 2.5x, c2k 4.0x, and dc1000.4, the Arc Audio SE 4200, the Zuki 4 channel Eleets, and the US Amps AX-TU3604C. Any help or advice would be much appreciated. Also, I am planning to have one set of channels run my highs, the other my mids. The car is a 2004 tahoe with a 300 amp alternator, 2 bats, 0 awg, 10 farad RF cap, and will eventually have a US Amps AX3200de with 4 12 IDMAXs, ICONs, or Qs in a ported enclosure. The source is an Alpine IVA-W505, may switch with my 800prs and go active. And sorry the components are undecided but they will be soon, just need an amp with eno…

what is a good number, and what does this mean?

My brother has a 2002 Chevy Trailblazer (4.2L) and he was having problem with his factory head unit. He took it out thinking it was like other units where you can just make a simple swap and have a new head unit. It was a Delco/Bose unit and his Trailblazer has on star. I was told that you would need a different adapter (GMAH24B adapter) if you had onstar. Am needing to know which adapter does he need to buy to get his stereo working again? Or is there a way to bypass that stuff to get the stereo back on like you can do with the pioneer DVD head unit.
