Question about Car Audio & Video

2 Answers

Soundstream Reference Class A 6.0 car amplifier has entire bank of 18 low ESR capacitors blown along with 3 adjacent small resistors in the power supply section. What may have caused this and should I check any other components before replacing these parts?

    Looking for someone familiar with the old Soundstream class A amplifiers please.

  • Khan Powell Jan 05, 2011

    This is not a typical car stereo amp. It is 15-20 years old and utilizes pure class A circuitry. It is stable down to 1/4 ohm loads and cannnot be picked up on any street corner anymore, and for that matter any car audio supplier that I know of. While waiting for your answer I, by dumb luck, stumbled upon the engineer who designed and oversaw the production of these amps for years. He is now semi-retired and services these amps for 1/2 of what they are worth. I actually found one of these amps on eBay, which is rare, the other night and seeing the auction though and seeing what it sold for, he was right. Thanks for your time. If there is a way I can pay 1/2 of what I was willing to pay for a completely accurate answer for my situation I would be satisfied.

    Thanks,

    Khan Powell

The cause was most likely that it was overdriven causing this power stage melt down ,best advice is to bin it as it will cost more in time and labour to repair than its worth ,these sort of amps can be picked up from local electrical retailer from 100euros ,by the time you locate components and then solder them in is it worth it ,unless you enjoy doing it and have nothing else to do on a dark winters night then please do so .

Check the battery charger (alternator) and see if it is charging more than it should ..cause this is an issue due to a higher power shock ...and usually only the power supply will blow in this cases...replacing the parts should make it work ..Try to place a fuse on the power line for the future..same like the ones they use for the woofer amplifiers...

I have an old soundstream reference class a 5.0 and a set of mb quart pwe 254 10 duel voice coil subs. i would like to know how to wire this set up for the most power. parrallel the voice coils then run...


The Soundstream Class A 5.0 will deliver its full power at 1 ohms mono.
I think your subs are two dual 4 ohm voice coils.
If you wire the voice coils for each sub in PARALLEL, that's 2 ohm for each sub. To get 1 ohm mono, you need to hook up the subs in PARALLEL to the amplifier, in bridge mode. That's the way to get to 1 ohm mono. Please add a fan to your setup as the amplifier will get very hot. You will need to use a relay to hook up the amplifiers and fan(s) to or you will damage the remote ouput of your HU (if you hook up the fan straight to the remote of the HU) as the remote output of the HU is not designed for the amount of current a fan draws.
Good luck. If you need help with the relay issue, have a look here: http://www.caraudiohelp.com/newsletter/multiple_amplifiers.htm

Have a 1996 soundstream reference 1000s amp 2 chan. Want to hook up 2 2011 12 inch kicker cvt woofers 4ohm. What is the best way to run this set up?


I have Ref-1000s with two Pioneer TS-W1200C 4-ohm subs bridged in series. So it is 8-ohm mono load, easy for an amplifier, long durability, less heating, low current consumption. I have heard that this amp might break if used with low impedance loads.

When bass kicks in amp dims car lights and car amp gauge reads very low. Ground wire is 6 gauge about 18 inches long, power wire is 8 gauge about 8 or 9 feet long. subs are wired according to owners book...


The problem is the amplifier is drawing more amperage than the alternator can provide. Install a capacitor in the battery feed line to the amplifier (can be purchased at any car stereo store). Do not go with the cheapest as this is a storage battery and like a battery cheap ones fail quickly.

Blown resistors in Soundstream Reference 300


Dude I hate to say this but the whole thing is shot. I am a solder/ board repair technitian for the US Navy and by looking at these pictures you have not only bad components but also a burnt borard. This is what they call a multilayer board which means there is more than one layer of circuitry. Looking at the resistors I am able to see the board waffers which means in order to repair this problem you will need copper to repair the tracks, small eyelets to replace the through-the-board solder joints, eppoxy, verry percice dremal tool, a steady hand, lots of patients and time. I wish that there was some good news to tell you but I am sorry. By the way the resistors appear to be about a 200 ohm resstor with a tollerance level of +/- 10%

Protect light stays on


It's likely that the output transistors have failed. If you measure the resistance between the second and third legs of the large transistors adjacent to the large (green?) resistors, you'll find several that read ~0 ohms. Its likely that only one of several that read 0 ohms is defective but all that read 0 ohms in the board are operating in parallel and must be replaced together so they match (electrically).

Disconnect the amp from the power source BEFORE trying to measure the resistance across the resistors.
