Amplifiers / Head Units / Processors / Electrical

Was looking for something today, and found this hiding under some stuff. Anyone ever seen one like this or better yet used one like it? It looks to be over my head unless someone could dumb it down for me. I set gains by ear, but if this could be used I would like to play around with it some. There is no manual that I can find. Maybe I could contact the manufacturer, but thought I would ask here before I put too much effort into something that Maybe cant even be used for what I want to do with it. Here is a pic, sorry it's crappy took it on my Blackberry. Leader LBO 525L Oscilloscope 50MHz Any thoughts ?? Thanks.

I was going to order my d3100 for my saz3500 tomorrow but i see a lot of good talk about the deka 9a31 and the 8a31. Will i come out better by getting two of the dekas over one d3100?

Holy f! I was just looking at the AQ1200D, and then I looked at the Digital Designs M1a, and they look almost exactly the same, here's what I'm talking about. DD M1a AQ1200D DD M1a AQ1200D The only difference I see, is there is no remote connection on the DD M1a, but everything else is exactly the same, and it's all in the exact same place. What do you guys think?

Im on a tight budget and am not resorting to Hifonics, so my other option is Audioque 1200D. I know a lot of people on here are Sundown lovvers, but I havent heard anything bad about Audioque other than 1 person having a problem on here a long time ago. Anyone got anything they could share with Audioque, I know the son or father 1 of the 2 also owns and runs Digital Designs, so cant be all that bad right?

Sorry for asking such a basic question but I used the search feature and I can't find anything on it. I am planning a build for a BL 15 in about 4 cubes and I need to know how many RMS I can safely put out on a sundown amp with a 130amp alternator without dipping below 12v too severely.

Hey all, I have a USB and the jack that connect to my iPOD. Is the USB just for information/control and the jack for the music? Can I use the jack for input from my PC? here is a link that has a pic of the back, the top left corner has 2 wires coming out, the bottom black wire is like a regular headphone/mic/line in/line out jack. Can I run a PC/laptop out into this to playback PC/laptop sound through my system? Also, when i purchased the $900 unit a key reason was for the optical out... listed at this site still, though discontinued. I spent an extra $100 for an optical cable only to find a rubber plug where the optical out is supposed to be, was told by my local Alpine …

I have one run of 4g to my 730wrms amp, with big three done in 4g, but I'm still dimming really badly. im almost positive its my batt, but i haven't tested my alt yet.. anyway, which of these batteries should i get (to replace stock batt): kinetik hc 1400 - ah:60 amps: 1500 kinetik hc 800 -- ah:36 amps: 950 or something else that will hopefully solve my dimming problem? i dont know much about batts, any advice would really be appreciated. thanks to all.

I have heard a lot about welding supply and coppercableman on e-bay, what about wire and supply or electron beam (EB-flex) wire? Also I see that 1/0 welding wire in general is rated for 350 amps at 50 feet while 2/0 is rated for 400 amps at 50 feet. I don't expect more than a 20 foot run at most from my front to back battery so what size cable would you guys recommend for a Crescendo BC3500d at one ohm with a 300 amp external fuse rating? Lastly I notice there is an ultraflex cable available from welding supply (as well as directwireusa.com) that claims to contain 4x the strand count of the standard wire yet the amperage ratings are the same?

ok i have had this amp hooked up before.i have a deka intimidator in the trunk and 2 100amp fuses going to the amp. it was a beast but one day the fuses poped randomly and i have no idea why. i bought new fuses and now it turns on for 5 seconds then the subs pop and it turns off... i have redone the grounds thinking that was the problem but it still does it idk what to do anyone can help me??? :/

hello everyone, I recently change all my system and after the installation i get a lot of engine noise and alternator noise. the install was like follows: Alternator: a 250 amp Ford alternator modified to use a voltage regulator, so it generates from 10.5 to 18 volts. Power wire: upgrade to 0 gauge from alternator to main battery, to second battery, to capacitor, to distribution block. Ground wire: upgrade to 0 gauge from alternator to engine, to chasis, to battery, to second battery, to capacitor, to distribution block. Amplifiers: 1 Memphis st-1600d to subs (2 10"Ascendant Audio) 1 Autotek 500s to mids (4 5.25" Crossfire) 1 Pioneer Gm630…

Ok here is the deal, I have a 08zx750.1 mono kicker amp & unfortunately I sent it out to kicker because I was having problems with my amp cutting off and on, when I turned up my music @ high volume. so kicker repair center diagnosed it and told me that the pcb board was cracked so he gave me a deal of 2010 ZX 750.1 Brand New with 2 year manufacturer warranty for the price of $209.00 or to return my original amp back to me. I was wanting your in-put whether I should get that deal for that brand new 2010 Amp for $209.00 or should I just invest my money on another amp? The set up I have is a 12' inch L7 Kicker dvc 4ohm & I will not be upgrading to add more subwoofers…

Well, I've installed a complete new system in a friends SUV (minus a headunit). Everything is going great and just trying to tweak thinks a bit. One thing that is real obvious is the low bass extension. Is this a problem with having a LOC instead of an aftermarket unit. I have heard that this can be a problem in my situation. Is there a cure for this? I would like her to have full range capabilities. Thanks.

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…

hey, i have 2 12" sundown SA'12's soon to be 4 or 6 in total. they are all dual 2 ohm subs, i wanted to know if any 1 has any suggestions for a amp that will give at least 2000-2500 RMS @ .5 ohms or 2 ohms and no more than $400 plus shipping. let me know if you have something your selling under these terms and or let me know if you know any amps that are able of doing the job for my system. thanks

Will it make a big enough difference in upgrading quality of my midrange amp but not power to be worth it? Will it make a difference in the sound of my? Or is 400 watts 400 watts and switching amps to a higher quality amp of the same power not make a noticable difference?

The amp has 5x30amp fuses, so what type of cables and fuse should i use....I'm thinking 2 gauge cable from batt to distribution block and 4 gauge from block to amp what fuses should i use?....the dude at the local stereo shop said the amp will not actually pull 150amps and said i would only need a 120amp block and i think it had 2 60amp fuses in parallel or something like that IDK and what should i use near the batt, the same?

we installed my single din headunit yesterday and im getting the movie playing through the speakers but not the actual video showing,could we have just missed a connection in the back?thanks for any information...

Ok i need to know which one of these amps are the better one to get (am running a 1 ohm load). I narrowed it down to either the Autotek MM 2000, the Soundstream PCX2000D or the Soundstream TRX2000D. I would like to hear from anyone who heard these amps. And which one of these amps do rated power or is closes to rated power. Any input?

Amp warranty at .5 ohms?

so my friend picked up a mechman 220 for his dodge avenger 2012. with his factory alternator he had some decent dimming of lights and gauges even when cruising down the road. with his mechman he says his voltage will drop to 11.2V on the alternator stud and his car has shut off and restarted itself during idle with the mechman but never with his factory alt. he used an amp meter to find out he has about 65A at idle coming from the alt under load. first off how accurate is that measurement? secondly what steps should one take to isolate the alternator vs a ground or other issue in the system? his system power is about 2KW with a JL 5 channel powering rainbow door compon…

Got my temporary ap1500d in the mail and installed. Set the gains via voltmeter, which I know is not the best method but thats what I have currently. Also tried confirming with my ear. Have 0 to 4 gauge reducers both put in, and included a picture of everything. Wired at 2ohms, voltage doesn't drop at ALL before protection light kicks in. The old amp would drop the voltage into the 12s. Gain is not even a 4th of the way up. With the new amp, its not as loud as it was nor is there as much flex as there was with my mtx7801d. Did I do something wrong? I feel this amp should be "putting out" better than what it is.

question is if im runnning stock alt, big 3 done, and a freshly new crescendo bc2000d pushing a fi bl 15,at 1 ohm. if i get a kinetik battery would it solve dimming problems on a stock alt or should i cut my losses with that idea and save a bit more for my sweet 270 amp mechman alt.

I recently did a install using a audiopipe ap3001d (older 16volt discontinued model) on two 15" kicker l7's in a seald enclosure 1.5cuft. each. The amp was shocking strong. But on to my question , has anyone dealt with the audiopipe apsm 1500 mono block? And if so do you think it would be to much for my two first gen. Dcon 12's in 1.2cuft sealed inclosures? And ps. can a box from sketch up be uploaded on the site? If so how? Thanks for all help.

So I couldnt pass up the deal on the SA line on here and purchased an SA-12 last night. Now it needs an amp. The car has a small alt, 70 amps. I want to keep it all under 1000rms. I will be running a 2 channel that makes 140rms total so I'm looking to give the sub anywhere from 500-750rms at 2 ohms. 600 would be ideal for me. My budget is 220 with shipping. What would you suggest? So far all I can think of is either an MB quart onx 1000.1D, a kicker ZX500.1 or a DX1000.1 (makes 50rms more than the ZX)

I'm looking to buy around 50 ft of 1/0 awg power and 25 ft of 1/0 awg ground wire. Whats every ones thoughts on knukonceptz? It was introduced to me by a local friend and I'd like to know what you guys think of it.....
