I'll always love the 90s Soundstream amps. Had a Reference 300, 500, 700, 404, Class A 5.0, and a Class A Picasso. Along with the BLT line transformers, these amps sounded amazing. Used alongside SPL 60 components front and rear and two SPL 12s. I paid $699 for the Picasso new and people thought I was nuts! Lol. Until they heard how crystal clear it was. Not to mention how stunning it looked next to the 5.0. Chrome and beautiful. The reference amps of this area are some of the absolute best amps ever made in car audio history. Period. Wish I still had everything from back then. Hit 140 fb with the 700 on the SPL 12s and 142 with 5.0, same car same subs. Miss those days. Love your content. Big fan of the channel!

The younger crowd won’t be able to appreciate the fact you could roll through the judging lanes with a 50 watt amp that could drive two efficient subs with around 200w of power. More over these amplifiers had some of the best sound signature. Super clean output. A pair of these in 0-100 watt class in the right build could be unstoppable.

@@n.shiina8798 Try cars like with two Orion HCCA 50s and two Orion XTR DVC 10” subs doing 145+ on Flashdance… on the dash. My own personal competition vehicle in 1995 was a regular cab Nissan cut through with three C12” kickers in a sealed enclosure, running off of a Soundstream 6.0. That’s a 50x2 amp. That truck did 143dB legal on flashdance. 146dB outlaw. By todays big system standards these aren’t super loud numbers. But believe me these cars with highly efficient subwoofer could get plenty loud with these small output amps.

Love the old Soundstream amps. Used several of the all chrome classs A references amps. Was a HUGE fan of the Van Gogh series, ran the VGA 500.4 with a VGA 1600.2, dual 4 gauge platinum power inputs, 115dB S/N ratio >500 Damping,Triple Darlington output circuitry, large low ESR Capacitance banks' they were some of the best made equipment I was lucky to have owned. They were famouse for the blue and the red, milltary grade 6 layer PCB bourds, audio grade resistors and beautiful board layouts.

@Hammerback0 6 месяцев назад

Military grade? I figured they would need to use boards of a decent quality in order to be robust enough to survive the abuse of car audio. Strange.

I installed a couple of those in a BMW back in the day. He also used a class AB Soundstream amp (I think it was a S200) bridged to drive a 12" sub mounted through the rear seat arm rest. If I am remembering the correct car he also used an Audio Control crossover and Epicenter, and ADS plates in the back and 320i in the front. I honestly don't remember what head unit he used, but I do remember that it was really clean and solid. It would not be competitive even back then, but that was not the goal anyway. It was supposed to sound good and be fun, and it did that in spades...

@justinm1621 Год назад

Hey there Big D! I'd love to see the high current and 12v tests. I ran these amps back when new and still do. Always loved these. Shocked to see the low efficiency. They do get hot. Got to have some fans for sure. The sound can't be beat imo. I also run a couple of mc300's, a Picasso, and a d200. I would love to see you test those if you ever get hold of any. Thanks for all the vids! Rock on!

@Choralone422 Год назад

Class A/B great for mids and highs but not the best choice for a bass amp for long term use at less than 4 ohms. I would know. I used a class A/B amp for subs from the mid 90s well into the 2000s, and that sucker would get HOT after a longer play session. The class D amp I use now outputs over 3x as much power and stays relatively cool all the time, even wired down to 2 ohms.

@jlev505 Год назад

I’ve got a class A 10.0, 5.0 and 2 rubicon 1002 first generation. Soundstream amps are extremely efficient at creating heat! They create crazy issues due to switches and pots that will drive you crazy trying to repair them.

The amp isn’t rated to be played at 1ohm high power bridged. Just a heads up. I know it shows it in the manual but it restricts its output. Also. Really quick question. After you deoxed it I noticed you left the switch in coherent stereo, did you flip it to mono off screen? Not being a pest. Just making sure. Thanks buddy

@jeanious2009 Год назад

11:45 that resistor is part of the -/+15v rails for the op amps. Pretty cheap design if you ask me, they could’ve used 1.00 15v regulators and prevented from having a large resistor that heats up to the point of cooking the PCB. I’ve seen some PCBs with charred spots underneath those large resistors.

@bigdogbrodavepresents6178 Год назад

SOUNDTREAM amps have some issues with resistors getting excessively hot to the point they MELT SOLDER (10.0 1st gen). Ya can BUMP UP them to a more robust resistor and that helps matters a lot. These amps run excessively HOT... yep. BDBD/2023

@Tegelane5 Год назад

Maybe rail voltage was too close to maximum input voltage of regulator. With heat, regulators SOA is even lower, so it could fail even sooner than resistor. But yes, transistor (not resistor) with zener is what I'd expect in a amplifier like this too.

Gotta see those high current pulls!

@justinwozniak2585 Год назад

definitely want to see high current tests. just installed my old reference 200 last week. the gain dial was a little crunchy.

@johnbooth3 Год назад

I would love to see the high current numbers. I always wanted those amps but couldn’t afford them. Friend of mine had one and it worked great.

@Atomwaffen-y3s 10 месяцев назад

I still have one of these. Anyone who thinks MP3 is satisfactory for playing music will never notice the difference between it and a D class. But with a decent source, you would think that a crime has been committed in this world of D class amps. That’s why I still run a late 50’s era Class A amp in the workshop.

How did it draw 58.8amps through a 30amp external fuse?

@gunnar1911 Год назад

It's the amount of time spent overcurrent as well, from the littelfuse website. C. Time-Current Characteristics A fuse’s time-current characteristics determine how fast it responds to different overcurrents. All fuses have inverse time-current characteristics, so opening time decreases as overcurrents increase. Time-current characteristics are presented graphically on standardized “log-log” paper. Figure 1 is a sample time-current curve for the MAXI Fuse series for fuses rated 20-60A. Current values increase from left to right, and time increases from bottom to top. The average melting time for any current can be determined from the curve. For example, from Figure 1 it can be determined that a 20A MAXI Fuse experiencing an overload of 100A will open in about 0.5 seconds. At 40A, the same 20A MAXI Fuse would open in about 9 seconds.

@@gunnar1911 the test was a certified run and most of us will send it for longer than .5 seconds. In fact I run my amplifier at full tilt for approximately 5 minutes or more. So I guess with your explanation I couldn't run this particular amplifier more than a few seconds at full tilt before popping fuses. Hmmm

This gen of amps is fabulous For mids and highs its hard to beat the old reference 200 300 500 its seems to me the ones with XS/.0 or other had x-overs and had issues with them but the non card ones were good for the most part and the best sounding car audio Amps I ever herd and load em up and they get even better like few others

I use to be a dealer back in the day and I used these to battle against the Orion HCCA's of day with great success but this design had issues with the screws used in its terminals that would break over time and would cause issues trying to remove and a few people never read the manual mainly on these Reference's high and low power switches on the bottom of the amp

I demand a redo. You did bridged mono tests in high power mode instead of high current mode. Do a part 2 for this amp in high current mode.

@550n440 Год назад

High current test would be a cool thing to see. I didn’t feel like it changed the output drastically with my Reference 500 but I had weak electrical back then.

@volvo09 Год назад

It should only make a difference driving low impedance loads. You can't just shove more current through a high resistance circuit, the resistance has to be low enough for the amps output. When he tests high current mode pay attention to the data sheet and what ohm loads are used for testing. He'll be able to test lower (amp was rated to .5 ohm if I remember correctly) and that is precisely where high current would be needed.

@@volvo09 I haven't read the manual but I'm thinking high current mode should have been used for the .5 ohm tests to get the right numbers.

@@550n440 what was your speaker ohm load though? It won't help at all if you were above 1 ohm. I won't give an in depth electrical lesson, but real quick it's why a 55w 12v car headlight is much lower resistance than a 55w light designed for household voltage. You are selecting a voltage range to drive your speakers. Ohms law.

@@v12alpine I bet he'll do a new episode and we'll see the difference, pay attention to the low ohm loads and they will go up.

i remember modifying one of this amp to run at higher idle current. technically forcing them to get more class A power region. told the owner to not to run the system without aircon lol
