so i am gonna get me a 3000d and i want o be able to run it, my zx650.4 and my car at full tilt sometimes so this is what ive come up with d2700 up front d3100 in back big three in 0/1 and one run back to the saz300d ive got 4ga ran already for the zx650.4 how am i doing so far?

Do any of you guys know what's the maximum unclipped output voltage for a PG tantrum 1200.1 at 3 ohms?

I have a lil over 700$ to spend on an amp for my 18" BTL I was thinking on buying a Rockford Fosgate T20001bd for a lil over 700$ And money is kinda tight with college coming up and bills and such.. Or just wait and save up a little more cash and get the Sundown 3000D Its really just a ground pounder and im not really concerned about numbers on the mic.. My question is, Is that Rockford a good amp to push my BTL? I just know how Sundown is all good talk and wonderful customer service..

hey guys and girls, I've been looking around for a H/O alternator for my 03 VW Golf GTI. I was speaking to a representative from Kinetik's about power cells that I will be needing to power my soon to be Sundown Audio 3000 amp. The representative told me that the higher than amperage from the alternator, the more power will be drained from the engine. He was also telling me that it is a big enough drain since I drive a 4 cyl car. Soon after I spoke to a representative from Ohio Alternators and he told me that the loss of horsepower would only be be a maximum of 5 from the engine with a 200 amp alternator at full power. Anybody have any input on the situation? This is my da…

Hey guy don't know if you've heard anything about the JBL GTO 1400.1 amp. I was thinking of changing my older PG Tantrum for it. I'm currently driving a JL 13w7 with the PG but I think it's not putting out the wattage it says it does, I mean the fuse rating is only 80 amps compared to the JBL 160 amps. What do you think?

I bought a Sundown 100.4 refurb from DB-r a while back while it was on sale. When i got around to installing it, it was blowing fuses on the distro as soon as you hooked it up. So I sent it out to DB-r Tuesday before thanksgiving and I recieved the amp back TODAY (1 week and 1 day later). I am completely amazed with it being the week of Thanksgiving I received the amp back so quickly. That includes shipping time BOTH ways. The whole time it was out DB-r kept me updated with emails. I just wanted to give credit to DB-r for the excellent work they did. :bigclap:

I have a really small 2-door car. I need a ballpark on how many ft of 1/0 to buy to do the big 3.

so does anyone know of any companys making any all tube car audio amplifiers anymore, if so, who are they, and if you can supply any details about them, that would be great

My 2005 civic has only a 70 amp alternator and I was wondering If I can run a 500 watt amp without problem? Will my lights dim at night? This will be the only amp running and I would do the big 3

Hi guys. As the topic states. below is what I have considdered so far pls give advice .. feel free to add and give a reason. preffer not to get processor just yet. system will be used for 2-way active. eclipse 7200 MK II (this is what i wanted to get but now people say its not all that) Price around s$1050 alpine 9887 around $800 singapore dollar clarion D2 (price not sure and the ugliest of the bunch) Pioneer DEX-P90RS (looks promising but way over budget and no-one here have it, so that i can audit it. s$1500)

I have a 3 way electronic crossover 18db slope and rta on my Head unit. I have 3 6 volt preouts front, rear, and subs, I have my tweets run off front channel and my mids ( 2 5.25's ) off the rear channel and the subs my question is. I know what freq the crossover points are, but I am not sure what Q is on the crossover, I can adjust the freq range and the q of the crossover. And I think I may be doing my high and low pass on the bandpass portion incorrectly. I have the high pass set to 3500 and the lowpass set to 100, was not sure about the Q so I left it alone. I have not done anything with RTA, I messed with it some but could not tell a real difference in positioning b…

If I had a 15" Icon and a 1000 watt amp would I need to get a new battery under the hood, do the big 3 or get a new alternator in a 2004+ Explorer or a 2001+ Tahoe? What about 1500 watts?

Which one sounds the best to you? No dvd players or navigation systems... just regular 1/2 din cd players

Between these two headunits which one would you choose and why? Im trying to decide which one I should get and want to know the pros and cons of both. If you have heard both then that would be great!!!

Well as soon as it powers up, it starts to oscillate on one frequency whether or not there is an instrument plugged into it or not. And it doesn't change when the instrument is played. Pretty simple set-up. Uses a simple linear power supply and an op amp as an output device. Could it be a bad input R? I had a similar thing happen with another amp when an input R was broken. Any other thoughts?

I just found an alternator on ebay, and im not sure how much of an upgrade it is, but it definitely is one... http://cgi.ebay.com/ebaymotors/_Car-Truck-...bayphotohosting Most likely 165 is its max, with a lower idle. Im not even sure what my stock alternator is I want to say 85A, I have big 3 with 1/0 and with my 1500 watt amp with moderate gains I drop to 10v or so under heavy pounding, with severe dim. Is this alternator an adequate upgrade, or should I save up and hunt down a slightly better one... I dont think i can afford more than $200 however. If I did get this do I need any other upgrades? My batt is stock btw, but with a good alt is a better one needed? By neede…

I've got a question for all of you in-the-know...... Running a couple of old-school Celestion AD15H's in my Tahoe, 'glassed in the rear corners after cutting out the inner rocker panels. Approximately 2.4cu ft each, with a 3"x8 1/2" port. I know these are rated at 600w RMS, but I'm pushing them with a Lightning Audio S4.500.1 at 2 ohms - supposedly putting out 250 watts to each sub, but sounds like it's making way more power than that - I'd guess closer to 400 watts to each sub, if not more. I'm using 4ga wiring from the battery to the amp rack under the Powerbass S-10's firing down betwen the front seats (nice midbass staging! LOL!). Have an old Kenwood KAC744 (40wx4@4…

Ok so I tried using the search engine (not working for me). But what is the specific duty of the gain on the amp? How should I adjust it? I heard I am supposed to match the volts with my head unit preout volts? I bump the system daily. Also if you need more info on my setup its in my sig.

I guess i've decided to get a new battery, and need to know what is adequate and still cheap for my system... I have a clarion 1500 watt amp and stock battery under the hood in a 2000 honda accord. If I run a second battery to the trunk is a kinetik hc800 enough to get the job done(stay above at least 11v) or do I need more and who makes the best cheap batteries? My local shop has a used stinger sp1700 out of their demo van for only 200, that may be the way to go but im hoping to spend less if possible Please and thanks for replies

tomorrow i am going to be doing the Big 3 finally, but am unsure of whether or not on any of the connections i should have a fuse holder, because i have heard both a yes and a no. please help

Plan on running two sundown 1500's with two Odyssey 2150 batteries in the back and one Odyssey 1200 under the hood. Going to keep my factory 130 amp alt to run it. Question is, how many runs of 1/0 should I run from the front battery to the back two? Probably going to just ground to the chassis of the car in the back. Thanks for the help

Okay so I'm trying to get a estimate of how much wattage I can safely put out without harming my amp's by the voltage dropping. I have a relatively small car, it has a 70 amp alt and I'm not sure about the battery. I was originally going to just run 1000watts on stock electrical but I figured if I upgrade my electrical I can go a little bit bigger. Now lets say I do the big 3 on my little car and I add a deep cycle battery in the back for the amp, how many more watts would I be able to run? And one more thing when you have a voltmeter what is the danger zone in volts? I think it was 11?

im going active in a month or 2 and i just saw some kicker zx100.2 amps on ubid.com. the bid is closing friday and i think i could get 2 of them for like $15 each (not including shipping). they are factory refurbs. ive purchased a kx250.2 from them previously. my idea is to bridge them to each mid and use my 250.2 for tweets. will this work? might hold off and try for a zx 150.2 or 200.2 next week...

I'm about to install my system, looking around at the stuff I have sitting around, and I started to wonder if there may be a better way to do this. Here's my plan: PG RSd 65 components in Front 2x Sundown SD-1 (the old 8 ohm ones - which creates part of my dilemma) sealed in 1.5^3ft. Sundown SAX-100.4 So, the original plan was simple, run the components off the front channels using the passive XO included with them. Run the subs parallel off the rear channels of the amp. Lots of flexibility with the subsonic filters, bass boost, active XO in the sundown, as well as some basic stuff on my HU. Simple right? Then, I realized I have this old RF 200a4 sitting here unused. …

Hey guys, Just wondering if you could give me some insight on this. When I start to play a new song the front speakers start playing about half a second before the rear ones... The front ones are on an amp, the rear ones are going into the HU... any idea on this?
