Did this video help you?

Jason Denman: When will you test the 100ix?

Brandon Edge: i had a 4080 that thang was badass back in the day! some punk robed my home and stole my crap! I was afraid to leave the rockford amp in my car for fear of theft. goes to show if they want it bad enough they will get it! allso lost a linerer amp alpine HU and 2 kicker solo;s. watching this takes me back. thx

Pimphand Gamester: Good amps for their time but the new Power series demolishes it in SQ and features. The new punches have diminished in quality to be more of an entry level amp yet priced at mid level. One thing about the old school amps is that hiss when there's no sound...reminds me of cassette tapes between tracks. Oh and turn on pop. Still have the Punch 60ix in my garage where it will stay. Many newer amps sound so much cleaner and use less power.

James Dyer: Found a 160x4 at a garage sale for 5 bucks. No clue if it works or what I'm gonna do with it but Def a nice piece of audio history and the heydays of RF.

Alan Reid: In high school i had a punch 200 and 3 W6 JL 12's talkina bout serious bass, ahhh those were the days

John Redcorn: Dang Dereck, that's a nice collection. It's amazing how most of them are still in awesome condition.

Kevin Nieto: I had a punch 200x2 and a punch 40x2 (very first DSM transana amp) I bought the 40 broken and repaired pretty powerful small amp.

Goshindo Tanaka: a friend of mine had the punch 200 hooked to 4 mtx thunder pro 10" and boy you dont imagine how hard that car hit.

Danny Caballero: I loved my old Punch 150. Should have never traded it for my brother's computer back in the day. He stopped paying for the car he had it in and got it repo'd! I could have killed him when I found out. He never got the system back.

svtcontour: I'm droooooling. I love the old punch stuff!

TDoginNC: Hey Big ... do you have a Power 1000 ???

Dereck BigDWiz: Thanks for the comment. I don't currently have anything for sale, but make sure you are subscribed as I will put vids up of any equipment I decide to sell (usually goes fast!). Keep it old school BigDWiz - OldSchoolStereo-com

imthefercho: I love the simple/elegant design of these amps. Today you can see lots of huge, excentric, lighted, chromed, flashy amps that give no power at all.

hilltop985: @bigdwiz Man u have all that old school RAW power. Companies just don't make amps like they used to. I had a punch 40 on two kicker competition 15's back in 1997 and that little amp pushed those speakers like they had 1000 watts going to them. That old school power was true wattage and the amps were totally underrated. They pushed way more power then they printed on the box. I wish I could get my hands on alot of different old school amps. If u wanna sell any send me a message. Serious buyer...

Cutty: my dad gave me his punch 200ix an subs

Dereck BigDWiz: @normalicy I tested the 200DSM earlier and got 600w in peaks (not continuous RMS) in my 2ohm mono tests. I also used almost all of my Rockford amps at 2ohms mono, after having the ability to test them, I'm starting to see they don't put out too much more in 2ohms mono than 4ohms mono, just quite a bit more heat (well in the case of the 200DSM, I guess 100w is nothing to sneeze at). But, if you are using dual 4ohm subs (or a single DVC 4 sub), then you don't have much choice...

Dereck BigDWiz: @normalicy I've tested some of the DSM amps and you're not too far off. For RMS power, the 40 was around 225 bridged, with max power over 300w. I didn't have enough resistors to test the 200's output bridged before (my setup was 400w, new setup is 1500w+), so I'm excited to test it. I do recall the 100DSM is more powerful than the 150HD

Goshindo Tanaka: hey big d i enjoy your videos you should get the earthquake 700 bx amp i had one of those back in 1998 with 2 autotek gold series 15 in a sealed box and that hit hard as hell try to get some to bench test.

Mickey Pietrzak: @bigdwiz AS&S (or was it CSR?) did a test on the 200DSM way back when it was released showing the 600w range & I've seen others confirm it. The 40 was just a gut feeling and I was talking 2 ohms mono. Of course they're not rated at 2 ohms mono, but I ran one for years like that. Nice to see you've upgraded the resistor bank. I ended up stripping an old amp heatsink & slapping a bunch to it for a rather humble 800w bank. Looking back, I wish I bought twice as many for the 2/4 ohm option.

Mickey Pietrzak: LOL, you have a collection like mine. A bit smaller, but very similar. We were probably bidding against each other a number of times. One of these days I'm gonna find some space so I can lay out my collection. Oh & I'm completely confident you should get 600+ watts out of the 200's. The 40's get near to 300w.

TDoginNC: I don't think you have enough !!!!!! NICE

Keith Lewis: I used to ave a Punch 40 trans ana

Dereck BigDWiz: Sending U a message...

Dereck BigDWiz: @normalicy I have the May/June 1993 CSR; they tested 462w @2ohms mono at 14.4v and 354 @4ohms mono 14.4v. This is the test Rockford used for all of their early DSM ads, b/c the tester said he would choose this amp if his life depended on it (or something like that). I have the article scanned if anyone wants it, just send me a msg w/ your email address. I had an 800w setup, but it was either 2ohms or 8ohms. Now, my 1600w+ setup can do 4ohms or 1ohm and I can also do 2 channel 2ohm tests now.

Jacobo Lalo: Your the man bigdwiz. Nice collection i with i could have all those amps it would be like a dream come true

Jay Holley: were do you get them all o_o

shawnk1rfnutcase: BEAUTIFUL! You know how I feel about the DSM's :-D

birdmanG6843: Thanks for your help.

njw360: I was fortunate to get a copy of everyone of these amps from my dad. I never knew how these compared to modern day and even how they compared against each other. Big fan of the 4020 and the regular 40. I'm scared to hook the 200 up in my car for fear of destroying everything !

Adam A: I didn't make it very far in the video, on the Punch 40's. The whole series, there was an amp, Punch 40 before RF labeled them DSM. (Discrete Surface Mount) They came out with DSM as a model number scheme, every 2 years so you couldn't jump warranty dating, due to number scheme. So it was Punch 40> 40 DSM> Punch 40 DSMi> then Punch 40 DSM ix, with active x-over.

Asimo380: Well I must say I died and went to heaven when I saw all these. I got a good portion of these and I got a 4020 and the 4040 and there awsome. But im starting to get most of the transannas. I really want 2 of the 200ix's

Dereck BigDWiz: @TDoginNC I have a really nice chrome shroud for a 1000, but no amp...yet. The market for them is out of control right now, so I'll patiently wait until they come down...

butternam123: LOL...i got the punch 400*4. i hardly use it along with a preicion power 404.4ch. never giving these amps up, with host of other amps and subs.

Dereck BigDWiz: @normalicy We should converse before bidding! No need to drive the price up on each other! I can share, but it sounds like you have enough? LOL

swaco1987: WoW, So Awesome. Love the Collection do you have any old rockford gear for sale?

Dereck BigDWiz: Yes, there was a Punch 40 as part of the "slider" series along with a Punch 100 "slider". The bass and treble controls had 3 sliding adjustments...low, mid and high. These amps were from the early - mid 80's before the first generation of Punch 45, 75 and 150's hit the market. This video was focused on the DSM amplifiers from around 1993 up until 1996 or so. Sorry you didn't make it far in the video :-(

Dereck BigDWiz: Great comment, thanks for sharing your experience with these amps!

Mickey Pietrzak: @bigdwiz I've backed off a lot on the amps lately. I literally have hundreds now. In fact, there have been a number of great deals lately that I let pass because I felt that someone else deserved a chance. It's funny though, I have 3 links & one box like you.

Dereck BigDWiz: @birdmanG6843 Thanks man, the DSM's are optimized for 2 ohms stereo or 4 ohms mono, but I wouldn't doubt it if your sub was a Dual 4 and you had the amp bridged at 2 ohms. This would explain why it got so hot as the amp was seeing a 1 ohm load. The DSM's can handle it, just make sure you've got good air flow on the amp. I used my 400x4's rear channels bridged at 2 ohms for years with no issues at all

usethisname8: 100ix i meant to type

Dereck BigDWiz: I should have mentioned in the video the 2 DSM links that were made were actually given to me by another RF amp fan. He took the time to cut down an amp in attempt to make "links". They are difficult to use, b/c you don't have an easy way to connect them to your DSM amps, they just "butt up" next to them. The factory RF DSM links work much better, but the attempt to make them was a great effort!

Dereck BigDWiz: Check your inbox bro

usethisname8: Know anyone interested in a 4080dsm and a 200ix? All cards and caps.buy the 4080 and I'll give them the 100ix free.i tried cl but if i get one more punk kid telling me his pyle 4.100 is better than the 4080 i swear....

svtcontour: I did some listening tests using some nice home speakers and a good source (uncompressed audio and a good DAC) and I compared the Orion HCCA series amps to the Fosgate Punch DSM series. I was fully expecting the Punch to sound worse but they were just as good if not a hint better than the HCCA amps (which are my favorite amps) for SQ. I was shocked actually. The punch amp I used was the 4080DSM. The orions I tested were the 225 and 250HCCA Digital reference series. I have new respect for DSM!

Mickey Pietrzak: @bigdwiz Yeah, I do know that the DSMs only managed about another 5-20% going beyond spec, but it was nice to be able to. As you noted, sometimes it's not a choice.

Dereck BigDWiz: @stayupfool101 Thanks...for the most part, I decided to stop after the DSM's. Only exception is the "25 to Life" amps.

jaronwhitener: Cannot wait for the tests!!!!!!

nikonman1: Still great equipment. I still run a 60x2 and 100x2 combo. I bought them used/pampered in 1998 and installed them one car. Ran for 4 years, then pulled them and traded vehicles, reinstalled them 6 months later and have been running them since 2003 trouble-free in my current truck.

svtcontour: Anytime. Thanks for the awesome channel where we have the opportunity to leave awesome comments :)

Dereck BigDWiz: Yeah man, I had no idea the 4020 was such as sleeper. I have a 4040 and 160x4 I'll compare to the 4020 sometime in the future. You just don't see amps underrated like this these days!
