These were what I had in my Thunderbird. Had the 2050 and the 2100 while dreaming of Orions 😂😂 Worked fine but I have always had the slightly subpar systems 😂 Finally at 50 I've started collecting my Orion pieces, so you can reach your dreams 😂😂😂
I'm sure it's been said before but it would be cool to do a series of videos or one big one where you test an amp before and then have it recapped and retest to see how much of a difference it makes
It would be interesting to see how much power an amp like this would produce after a recap and being refurbished. I wonder if it would make more power dynamically.
@@envisionelectronics Electrolytic type DC capacitors lose capacitance & insulation strength if stored for long times even if they were never used. The Al oxide layer on the metal foil depletes & causes the problem. So long story short; they lose capacity over time even if not used.
I had the 4050 in my 1980 trans am in 1993. I remember my dad ordered it from crutchfield for me for Christmas. I believe it was $199. We had a $200 limit for Christmas so it was definitely less than $200. Drove my MTX Terminator 2x12's and two horns factory box perfect back then.. Can still hear Metallica and AC/DC blasting. Back then the speakers didn't need crazy wattage.
You’re always official in my opinion my guy. But with this one and my first amp!!!!! You’re my God of audio bro. Salute!!! I got this amp in high school especially because I couldn’t afford the PUNCH 150.
I'm sure with a recap it would probably make rated power. Also in some cases the glue on those caps can become conductive, especially if the amp is exposed to a humid environment for a while.
Hey now, I represent that 38 grade in high school algebra!!! 😂 At first thought, I gave this amp a failing grade but after a little contemplation, I realized that for back in the day, this was still a decent amp. Decent is the key word. These were average amps back in the day.
i think the amp could hit its rated wattage if the caps were replaced.. the caps look really old like you said in the video. Nice nostalgic trip down memory lane from the 90s. i remember seeing these when i was in highschool.
Alphasonik had a series of really unique looking amps in 1992 that included the FA-100 C, FA-150C and FA-200C. They had a transparent cyro acrylic cover and Forced Air Cooling (fan). It would cool if Big D. could get his hands on one of those and test it. This was another awesome video, loved it!
I remember Crutchfield trying to sell me one of these when I called them in 1993. I was much happier with the Rockford Fosgate Punch 150HD I bought at the pawn shop!
Nice Derek, Crutchfield always had alphasonic amps. These were generally higher end amps, step up from Jensen and sherwood. IIRC they had a sister company Deltasonic as well. I think Deltasonik mainly focused on EQs, crossovers and line level components. Yes sir headquarters were in Berekely CA!!
I had the pma2030 30x2 amp running 12 mids and tweeters with a jet sound 125x2 running my 2 12inch kicker comps. I got the alphasonix from crutchfield. In my first ever competition I got 4th place out of 8 cars in the class. 👍🤟
I used to love looking at the Sunday ads for systems, loved looking at sixth ave, circuit city, the wiz and crazy Eddie’s. 10-11 years old clipping out stereo setups for sale amps and sub combos, my first setup was a dual 10 inch jbl bandpass with a cool from narrow port and the old jbl white amp, had to upgrade to fosgate all around at 17,-18 that was hella pricey
Yep i had one in the early 90s hooked up in seires with one pair 4 inch kicker an one pair high power pyle super tweets an let me tell you i had inline bass blockers on it . They screamed . Was clear an reliable
Derek I know you remember Alphasonik had a very cool Alphasonic amplifier rack It had the EX -2,or 3 Crossover Plus mounts for a 2030,2040,2050,2075,2100,or 2150 I believe you could hook up to 3 amplifiers It was a cool amplifier rack .It didn’t make the molex plugs actually look good I used to sell Alphasonik and my dad had a 2100 with 2 Punch 12” You’re right, all sonics, more most powerful amplifiers But they always made the rated power in most cases I did hook up a PA 2100 to a power meter .I was getting 110-115 wpc About 225 mono Officer camps sounded really good and they’re very affordable Only drawback was the rats nest wiring inside the amplifier Plus the god ugly Molex Plugs Derek ,Thank you again for making these amazing videos Actually, look forward to watching your videos I don’t even watch TV You should do the Binge weeks more often It keep your viewers glued to the screen Have a great week !!
@@bdkw1 I ran two of the 2075ix in a Geo Storm, ran one on the fronts and one on the rears, and a RF Power 300 on two 12's, basically it was a stereo on wheels. Those Alphasonik's ran cool and never had any issues with them.
I had the hcx-2150 back in high school in the mid 90s powering 2 kicker competition 12's in the recommended 2 cubic foot box per woofer. Filled up my whole trunk. Played nice and lowwwww. I modded the amp and added spring terminals for the speaker wire rather than that terrible pigtail. I wonder if they would fare better power rating wise with replaced caps.
Cool review crazy just got a 4035 looks just like this says 1992 on the board amp dosent seem that loud but man it can boom boom boom idk how but it's got a clean base not loud but deep hard to explain I couldn't stop playing this amp. Also picked up the 2030 7" x 7" it's the same bass crazy 😂 had to make a plug 😅 used a molex from old hvac unit repinned it the correct colors lots of fun..
I replaced the Samyoung caps in my Schneider SPA4000.4HC amps without taking a proper careful look at them. They appear swollen on top at a glance, but they have a plastic top that is just like that you could press it down, like a "poptop".
Having sold Alphasonik in the early '90s, I would guess that amp would make rated power but not much more when new. The PMA series was a huge improvement over the MA series, which would self destruct at anything less than 4 ohms.
Interesting video…I thought the PMA amps were all class A. I had the PMA2175 and it was class A… and a beast. It would kill a car battery in a New York minute if the motor wasn’t running.
I owned the PMA-2150 class A Alphasonik amp back in 1992. Beautiful sound because of it being class A, but it ran hot. Hot like i had taken 2 fans from computer power supplies and attached them to the heat sink right over the Alphasonik label. I think the poor efficiency you are seeing is because that should be a Class A amp you are testing. It was sold through Crutchfield and advertised as having a "military grade circuit board" for durability. I used this amp to power 2 Pioneer 12 inch subs in my1969 Camsro.
Im a US Acoustics fan and i've recently seen some pics of a us acoustics 2150 with alphasonic logo on it.I noticed from reading alot of these comments that the alphasonic model number is the same as the us acoustic model numbers.i still have some digging to do.
Alphasonik also offered a rack system with built in fusing and mounting grommets for the amp feet and wiring. I owned the rack, a PMA2050 and PMA2100 amps. Looked great but, wasn't particularly impressive as I recall.
I remember the original PMA2100 from a few years earlier being VERY popular, being a good value compared to the questionable fleamarket brands at the time.
They were decent for the money , when a truly great amp would set you back 2-3 times what the Alphasonic and others like it would cost ya . It was a different world then . Seems everybody with anything to do with the electronics world had a line of car audio equipment , so yeah , those directories were damn near indispensable . Some things haven't changed all that much , either , especially the ILS ( If Lightening Strikes ..) ratings standards for amplifier power output used by the most " budget oriented " manufacturers .
I wonder if the amplifier was connected to power and turned on and left on for a few hours or a day if it would possibly produce better results.... The thinking behind this is if the amplifier has been sitting around unused, it's capacitors have possibly gone to sleep and need some time to wake up, that is unless they have dried out and there's no chance that they are coming back from the dead...... Sometimes you can see the capacitors getting hot through a thermal camera as they are waking up...... I think that it would be an interesting test especially for these old timers...... You never know, one amplifier might surprise you......
Hmm. I take back the 'solid piece' comment. Or I need to edit it to solid POS. I just remembered this was the series of amplifiers that caused my favorite old school car audio shop to call the amps: ALPHATOASTER
Maybe get it recapped and see if it does a little better? These were good amps back in the day. Lots of guys were running them. Their address is 3130 West 15th Ave Hialeah, FL 33012 Which also comes up as the address for Orion. I didn't know they had anything to do with each other? Big D this week has been great but also depressing. I just don't see many young people into systems anymore. Last month I picked up a kicker 4 channel amp and was talking to one of the guys that worked there, and I asked if he ever gets to install big systems anymore. He told me they don't install amps that much period. Most installs were cameras and remote start. Why have people become satisfied with stock audio? They still suck compared to aftermarket.
😆 🤣 😂 😹 at Saved By The Bell, not wrong there. Would been a starting trend if they named each model after the Cast😅 i think this model would be known as "Kelly Kapowski" 🤩😂
Very disappointing, was expecting a little more. But it does seem to slap that little sub around pretty good. And in some cases that brown glue can become slightly conductive and cause some problems.
Big Deee i really don't think that amp got a fair shake and realy do you? I can see caps swollen and it could be leaking!!! I think it needs to be looked at again in the future cum on guys help him out thanks Big D!!! Love it though!!!!
Hey Derek and old schoolers... This is a video of a 1991 IASCA event I competed in. If you pause it exactly at 5:07-5:08. My light blue 85 accord 2 door hatch is lined up in the judging lane. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-g85gHjNM8gk.htmlsi=v_EfKvVExgg-tT4D
The amplifier needs a recap for sure .Tiers capacitors are a huge issue .Sometimes absolutely nothing wrong with transistors /fets but capacitors have an average ge of only 5 year life span
So just look at that, single sided board🤮 looks better organized than that over priced pile of Massachusetts caca. Every alphasonic I sold ran hot which equals inefficientsy. Thankfully I only placed a minimum order one time. Coustic was my economy brand of choice.
Amps back then didn’t need to be power houses because the subs were more efficient. You also didn’t need a 300 amp alternator and multiple batteries in your daily. It was just a different time.
Love to see it BigD! I’ve got an MA-2075 and a PMA-2075 packed away that could make a neat comparo. I really think the older MA is much more amp than the newer PMA but your lab could put numbers to it. Had ‘em since college and won’t sell but happy to loan them knowing the possibility of failure…
