Pioneer GM-D9601 back by popular demand on the amp dyno

[@11bravomechinf27]

I've had this amp for a while and on multiple different subs and I'm pretty impressed with it. I've had numerous mainstream amps and this one ranks right up there with all of them.

Loved my gmd 9605...small and powerfuk

[@joshholden8561]

Me being a amp repair tech and looking at the parts used inside the amp this amp should be making $1500 RMS at 1 ohm all day long it's the week regulated power supply that holds this amp back that's the only one thing bad I could say about this amp is that the regulated power supply holds back the amps power capabilities quite a bit the power supply alone probably knocks out 35% of the power that this amp could make I've thought about changing the toroidal on the power supply and making it unregulated just the tinker with one and see what I could get it to really do there's a very good base layout of this board it's quite a good design.

Do it let’s see!!!!👀

[@drecrawford3410]

My 9601 makes about 1450 watts

[@justkiddin1980]

This thing is AMAZING!!!! Really one of the best amps i ever had best performance to price ratio…

[@joshholden8561]

This amp is a total sleeper beast the 9601 is a nice nice unit

[@joshholden8561]

The protection circuit on this amp are actually quite quite good u can get away with running like .80 ohm without the low ohm sensor shutting it down. I'm also a fan of using many many more caps but a tad smaller in size it's ability to rebound very quickly with the high dynamic numbers is a design feature when going with multiple medium sized caps the medium sized caps can charge and discharge at a slightly faster rate giving slightly better dynamic numbers in an overall RMS numbers than having just a couple really really big capacitors I prefer having multiple medium sized capacitors for the power supply and then having 2 very very large output filtering capacitors is my design preference on class d sub amps.😮

Cool! Keep up the good work!

Nice test man ..

[@joshholden8561]

The only thing I don't particularly like about this 9601 is it uses a regulated power supply if it was unregulated I think it would have much more potential because the output mosfets and the power supply transistors are well capable of putting out 1800 RMS with this board layout it's fully regulated power supply holds it back quite a bit and also it's a 2-ohm optimized amp even though it will run one ohm it's design is optimized for 2 ohm operation these amps also come with a birth sheet in the box when you get them new.

[@joshholden8561]

The sound does pretty much a decent amount more power on high voltage systems as usual for car amps the closer you are to mid 15 the most power you're going to obviously pull from the amp but this amp in particular if you run it around 15.8 volts does quite a bit more than rated .

[@joshholden8561]

I'm actually in the market to pick up one or two of these on the used market right now or I'd like to find 1 or more of these 9601 models that are blown I repair amps and the mosfets for the power supply side and also the output section is the same exact parts as high dollar jl audio kicker and about 50 other brands these amps blown are well worth fixing if u can do it urself so you're only specifically paying for parts to replace every single fet in this amp and still have 20 to 30 left over for spares would only cost probably $25 Max plus factor in maybe 20 bucks if you buy a blue moon off of somebody for 20 bucks or so you're talking $20 invested for a blown amp then replacing 3 to 5 dollars worth of mosfets then bam you got a brand new amp again. I haven't had any 9601 models come through the shop in a couple years but I've had several 8601 come in the shop pretty regularly since I wish pioneer would come out with a version 1061 ain't even more powerful model I think it was so quiet well as a matter of fact I know it was so well because the first two did anytime on Facebook marketplace I see a 9601 for sale people want you to buy their entire sound system and won't sell you just the amp so that screws up being able to find a nice used one on marketplace for a decent price or if there's someone is just selling the amp they want like $200 for it basically what it costs new if I came across a nice used one with the box and it's still in good shape iPad 1:50 for the amp if it was the box included amp looking great not all beat up rusted and scratched and of course working there's a lot of people that blow their amp and then wrap it back up in the plastic and put it back in the box and then put it for sale on marketplace like it's not a blown.

[@mrurdude0189]

I threw out 6 amps that were blown in one way or another only a few weeks ago, including a 9601 and 8601… I wish I saw your comment earlier. However, I do have a Gm-d8604 that’s having a weird issue. It’ll play fine and then at random, some channels will go “fuzzy” and play some horrible sounds. Sometimes the front speakers and sometimes the rear. Im happy to work out something with you. Are you in Australia?

[@elcaminosupersport]

The knob is NOT a bass knob it is a bass boost knob I didn't bother connecting mine

[@emeraldstevens8922]

Is it worth it to try repair one of these?

[@bdaudio9395]

I’m not sure where your from but in Australia, no they are worth it because you can find them 2nd hand way cheaper then the cost to repair

[@joshholden8561]

What voltage was you doing your testing at I couldn't see 14.4 ish? I only ask because the numbers ur getting look like 12.8 volt numbers I've tested these on my work bench quite extensively when one would come in for repair work.

[@bdaudio9395]

4 banks of ltos starting at 15.2 so 14.6 after full hit

[@joshholden8561]

@@bdaudio9395 okok not bad just curious

[@CHEVYK10]

sony xm2002gtr please

[@bdaudio9395]

I don’t have one to test sorry, but your more then welcome to send one in for me to test
