  2. Old Skool Memphis amp repair question?

    in Amplifiers

    Posted

    A friend of mine dropped off this amp at my house today. It's a Memphis 16-MC1000D, 2-channel 1 ohm stable. He said it powers up just fine and ran the living hell out of two 12" RF P2's but when he pulled it to replace the amp that is in his car now, he has power, but no sound? From the looks of the gutz, it looks like it means business. I told him I'm not much of an amplifier repair guy, I build boxes and re-cone subs more than anything else. So, I'm here to ask for your guys' input on what may cause this problem? I carefully opened the case to check for any burns or broken connections, but I couldn't really find anything. I did notice a slight burnt smell though. Here's some pics I just now took... Enjoy! :popcorn:

    Also, how hard would it be to replace the part(s) to make it work? I would love to gain some knowledge on how exactly an amplifier works and such. It's something I've been meaning to study up on, but never really understood it.

    I've got a pretty nice one myself, not to brag or anything lol. I'll grab a picture off Facebook here in a minute, I'm on my iPod. I've got a 60" pioneer flatscreen with an HDMi conversion, 250G Xbox 360 Slim w/kinect (not pictured), full 500w 5.1 pioneer surround sound partially homemade lol, two couches and a sectional free on craigslist, space heater, autographed Kottonmouth Kings/Big B/Tech N9ne posters, and a LOT more stuff. I add to it every now and again lol ditched one of the couches for a futon

    That's no joke, cartunes (a shop here in town) $25 for my 12ft of 4ga alone! I got all of that stuff in the first picture for $25 shipped from knukonceptz! I realize CCA wire isn't as conductive as OFC because it's mostly aluminum, but that's part of why knu uses a thinner jacket to allow a higher stran count. Otherwise it would be the same as 8ga, but a little larger than that if it makes sense

    Rebel, I'm realize knu wiring isn't real, but they do make

    very good wire by trying to

    balance it and make it

    comparable to OFC wiring by

    utilizing a thinner, tougher

    jacket, and a higher strand

    count. Of course though, anything is better than what I had! XD

    He was saying that it is "real", what do you mean by "real"?

    The KCA Kable from knukonceptz is 90% aluminum and 10% copper, making it more affordable @ 95c / ft

    Your ground should be the same size as your power. Make sure you can get your power straight from the battery as soon as possible. It's not very

    efficient coming from the fuse box. It's kinda like running 8awg

    half way to the amp and then

    connecting 4awg to the 8awg

    to make the rest of the run, if

    that makes any sense.

    Kinda, but not really lol from what extremeauto said, it could cause some computer problems in the future which I really don't need. If that's true, it will only be temporary till I get a 4ga line connector and some added KCA Kable

    Ok I'm in a bit of a pickle here. It seems like if there's not one problem with my truck, there's another. I just got my package from knukonceptz.com today containing my 12 feet of 4 ga KCA Kable, GM battery terminal, and gold ring terminals. I made the mistake of not getting enough wire or measuring first how much I would need, so I didn't have enough to get from my battery safely and securely into the steering shaft grommet on the firewall, and into my amp without being short, so I went to the next source of +12V power. I connected my power wire to the fuse box using the same terminal as the wiring that comes directly off of the battery. I have had to do this more than a few times for friend's cars who didn't purchase enough wire and it worked just as good as using the positive post of the battery.

    After doing so, I took a reading from my DMM and put the ground on a bare-metal area of my chassis, then put the positive lead on the end of the wire after I installed my fuse block. It read 12.4 DCV, but when I plugged it into my amp and with the ignition on and off, it read 0.3 DCV? I checked my remote wire, it was reading 11.3 DCV when switched. I also thoroughly inspected the guts of my amp to make sure nothing was disconnected or burned, and didn't find anything unusual. I also took my test light to the negative terminal of the amp with power and ground installed, and the light lit up for a second then dimmed out in a quick manner.

    There are two outcomes I'm thinking about this:

    1) My inline fuse is 80A, and the total amperes of my amplifier equals 50A (2x 25A). Could the inline fuse be too big?

    2) My ground wire is too small. It's the crappy old American Legacy "4 ga OFC" my friend bought for me. Knukonceptz 4 ga wire is actually about 10% larger than that of standard 4 ga due to it's CCA construction to compensate for OFC 4 ga load capacity) Comparing the two brands of 4 ga wire, the American Legacy looks more like 10 ga wire. Could this be a problem? Thanks guys, here's some pics

    I love getting new stuff in the mail :santa:

    The wire on the left is American Legacy "4ga OFC". It is the same strand count as the ground wire that is currently in my truck. And on the right, of course, is the KCA Kable

    And finally, here's the gutz of my amp. Nothing looked burned or disconnected when I looked at it prior to purchase (got in on Craigslist). It is only temporary though.

    If you think you have a solution, please let me hear it. I'm really excited to finally have a system again after going through a painful, treble-filled year after I sold my Rockford HX2 / Kicker ZX500.1

    Haha once but she turned out to be a psycho bitch O_O

    Allow me to bold "psycho bitch", there are PLENTY of those in Wichita! I dated a chick sophomore year who fit that perfectly. I used to race motocross every weekend so I went out for a practice sesh on a Friday (it's good to have friends that will prep a closed track just for you!) and she got SO, SO pissed I didn't take her that she called one of my boys she didn't even know and demanded that he picked up and drove her 22 miles to a track she wouldn't even have gotten into... Then she REFUSED to let me break it off, so I split. Lol

    So I met this chick a few weeks ago. She's awesome, a complete bass-head just like me, she's running a 12" Orion HCCA on a Kicker ZX750.1, and she wants me to make her a box (I guess my boxes are starting to have an impact on the West side of town lol). Just overall an awesome girl to me.

    I am more the type of guy to keep to myself if you know what I mean. I don't have a whole lot of friends anymore, didn't really have an interest in women (unless it was for one night! :diablo: ), all I was ever really focused on was school and audio. Every penny I got, I spent on audio. Anyway, this girl completely changed my mind. Don't worry guys, as long as I'm breathing I will never give up my audio addiction! The weird thing is, when I'm with her, I don't think about the stuff I usually thought about when I hang out with a girl... I'm pretty sure you know what I mean there. I'm not sure if I should be scared or happy? This has never happened before and I'm not sure if it's for the best or worse.

    Anyone else ever feel like this? In such a short time at least?

  17. Looking for ANY work in Wichita, KS

    in Help Wanted! (Job opportunities) - Need a job? Hiring?Know of a place that is? Post it. All fields welcome

    Posted

    I'm in dire need of a job, I have been unemployed for well over a year now and I'm just not doing very well. I've been building boxes and doing installs on the side just to keep my head above water. I am looking for any job available, but it would be a gift from the Lord himself if I could get a position as a box builder or installer.

    I'm 18, very well educated, as far as schooling goes I will be honest and say I have made some mistakes. I dropped out my Junior year but later on I decided installing is what I wanted to do for the remainder of my years, so I went back to school. I'm in the process of my Diploma right now, but my hours are very flexible as I can also do schoolwork from home.

    I do have quite a few very positive references from my enclosure builds and installs if you would like me to provide them, I've been building boxes and doing installs since I was 13, but I also studied on anything and everything audio related since 12. I am just in desperate need of a job to support myself, pay my mom back or at least help with bills till I get my own place, my dogs, and my audio addiction lol.

    If anyone knows of any opportunities, please PM me. I am still under the roof of my mother's house, and it kills me to think of how much of a burden I must be to her right now. I also have a little sister that currently lives with my mom and I and her d*ckhead dad makes $25k+ a month (his daddy owns the biggest Ford dealer... I mean "stealer-ship" in the Midwest) and is not willing to take more than $1,150 out of his paycheck to help my mom, sister, and (at my mother's will) myself and then has the sac to say "he gets overdrawn before the end of every month". My mother is also unemployed and she's been out of work for years. Like I said above, if you know of any openings or opportunities anywhere, please PM me asap. Your help will be greatly appreciated... Thanks!

  18. Last minute box design help!

    in Sundown Audio - GREAT Amps/Subs! GREAT Customer Service!

    Posted

    I'm about to start building my box as I have already gotten recommended airspace requirements and built a 3D model on Google Sketchup. My "rough draft" so to speak is 0.832 ft^3 @ 38.67hz.

    Here's my problem, would this be a sufficient enclosure for what I'm doing now? I listen to a lot of rap, dubstep, So.Cal "trip-hop", Lil Wyte, etc... There's a lot of lows in what I listen to and from what I've heard and read about the SA-8's is that they have stoopid low-frequency extension and can put out very impressive numbers in the right enclosure with the right power. I'd like to be able to reach those "stoopid low" notes, but still be able to retain a lot of SPL to show up some of my friends with dual 10" and 12" setups!

    My amp is only temporary, possibly just to get me through the break in period. It's an SPL Audio Z2X-820 and says it does 820w RMS bridged at 2-ohm, but I doubt it. It's only got two 25 amp fuses, but like I said it's only temporary. I'm hoping once Christmas is through I can get my AudioQue AQ750 and run that instead until I've saved up for my SA-8D2v.2 wall. Any suggestions on a tuning frequency coupled with the amp I have now?

  21. Anyone ever notice?

    How there's only three articles of clothing that you don't get bashed on for wearing day after day? Hats, hoodies/jackets, and shoes!

    I've had the same SRH jacket (finally broke it out yesterday! :woot: ) for about 3 years and nobody has ever asked me why I wear it day by day. I've had the same Nike 6.0's for about 2 years, and the same SRH hat for... 3 years as well? But when I wear my FiCarAudio.com shirt twice in two days, people get butt hurt!

  22. Need help designing an SPL/daily box

    in SPL - SOUND PRESSURE LEVEL

    Posted

    My Sundown SA-8D2 should be coming in sometime this week, I've been hearing about a lot of different sizes and tuning frequencies that work perfect for this sub, but I am not working with a whole lot of space! I am wanting to build around 0.8 cft^3 @ 34hz, but it's going to be impossible to get that from a box that's built under the rear seat. I'd like to be able to get the most SPL possible out of this box, but still be stable enough to be a daily driver. I've heard of these things outbeating 12's with a single 8" so I'd like to be able to turn some heads :dancing:

    My initial thought was to build it between the front and rear seats. Not whole lot of people ride in the back seat anyway (May do an SA-8 wall back there after it's paid off) so box depth isn't really an issue. Keep in mind the draw-up is just a rough sketch of what I'm looking for. I've already taken into account the displacement of the port and the bracing and it will put me around 0.84 cft^3 @ 34.67hz (according to REAudio's box calculator) and in another forum, a guy claimed to achieve 147.3 dB's on 600w RMS with an enclosure very similiar to the one I designed.

    As you can see, I don't have an issue so much with length. Mostly with height and depth and the angle of recline the front seat will have. I have seen how far these 8's can throw, and I definitely don't want the cone slapping on the seat. Sundown recommends that there's at least 2 inches between the bottom of the box and the bottom plate of the motor.

    002lhz.jpg

    Here's my rough drawing of what I was thinking. I'm just getting a tad tired of coming up with design after design and nothing ending up working, and I finally thought of this one. Simple, yet effective?

    016pqh.jpg

    Any comments/suggestions? I'm looking to get this done pretty soon, haven't had beats in over a year!

  23. Everyone I know hates systems what should I do??

    Yeah, I know my mom hates systems and it's probably because she hasn't heard a real one (used to all my friend's two-bit systems), but moms are moms. I explained to my mom why I love audio so much and I think she understands now. The feeling I get after months of saving money, building the box, setting gains, running wiring, tuning everything correctly, and hearing it all in the end is a feeling I can't replace with anything else. Pride, commitment, euphoria, and many other emotions piled up into one just can't be replace for me.

    It could be a lot worse, I'm sure no mother wants to see her kid sticking himself/herself with needles and bugging out for a couple days on end. AUDIO IS MY ANTI-DRUG! :woot:
