I had a cheater amp in my first system but it was a bit newer. I think it was a punch power 50.1. It would get hot after a couple hours of hard playing but it didn't die on me. I had an orion 4 channel running my mids and it died during the same time period, it couldn't take the abuse a teenager put it through lol. I just spent all day yesterday working on my system, installed a Rockford prime 300x4. I went with ct sounds speakers and jbl gto tweets. I need to build a sub box next.

I had a punch 100ix that I paid 425 for back in 1995 or 1996. Was a fortune at that time. Powered all sorts of subs. 2-12's 1-15. Always performed. Even in the winter it would get hot and then when it would cool the amp would get covered in layers of frost. Never had one single problem. Miss those old school amps.

I always ran Rockford Fosgate back in the 90's, starting with the Punch 150. That thing slammed! If I recall, the birth certificate said it was 306 watts, bridged. The Damping Factor was crazy good on their amps. I ran a pair of 12" Cerwin Vegas in a vented enclosure in the trunk of my 86 Cougar. When I played the Metallica black album, it could throw the loose change out of my center console.

I'm familiar with Punch from the early 90's. The generation of amps before they added those end-caps. The legendary Punch 45. I remember one little Punch 45 EASILY pushing two 12's without a hitch.

I've had the old Punch 40s and 60s made by Rockford Fosgate. As well as the Fosgate series one subs. Top notch. Those little amps are the ones with the chip cards you'd manually remove and put in one way for high pass and the other for low pass.

Really like this video. I remember the first time I heard this amp back in 2002 from a friend of mine. It was hooked up to 2-12" JL Audio W-0 series subs in a Q Logic dual bandpass box in a 2001 Chevy blazer...

ive had a few of these punch amplifiers over the years. and still have a 60x2 and a 200x2. solid built, simple and with lots of power. i used to know a lad that had a box built at wheel sounds, it housed 2 12" precision devices subs and run off a little punch 40x2. that thing was a real bass machine.

Amazing amps! My buddy had a Punch 50 I think it was, it was small but that thing pounded the hell out of two 10 inch bandpass in a 91 Honda crx. I couldn't believe the noise that thing made.

I had a Rockford Power 300 back about 1990. I think it cost me over $1000. My friend had the power 650 and it was sooooo powerful.

Always a rockford fosgate fan. I have the 50M Power. Old school rocks.

Awesome blast for.the past! A buddy had some old punches with the link caps that were Nickle plated running a few 15s

Man this brings back memories of happier times. '94 I had a Toyota MR2 and loaded it up with a RF Punch100 amp and a pair of RF 10's, lol. Also had a pair of Rockford 1" tweeters, 4" and 6" mids. They weren't that great but the whole thing sounded awesome. Had a really nice Sony CD head unit. Damn I miss that car.

I loved my punch amps and punch subs. I really liked the MB Quarts I had for mids and tweets too. 1000 watts to the 2 12inch punch subs and 600 watts total to the mids and tweets. A big stinger snap cap to keep it from dimming my headlights. But I can't remember what else I was using 25-30 years ago. But I was very happy with it.

I used to have one of these and one of the higher wattage ones. I love the way they look how the ends hide the wires. Everything now looks alike. Back then they cared about how it looked and tried to be original. I have probably 10 times the amount of power in my truck now but I swear it doesn’t sound as good as my 400 watt system back in the 90’s. Dereck, that amp you got right there looks like it’s in great shape. I have seen a lot of these over the years and they are usually beat up with the end caps missing and what not.

Rockford fosgate punch was always my favorite

Those end caps are heavy. It’s solid metal!! I remember them being so solid

I have one of these and a matching 50m Power. I had the x2 running a pair of 8's, mids and tweets in the kick panels and the 50m running 8 12's at .5ohm in the trunk of my '67 Chevelle.

is used to ABUST these amps all the way from the punch 40 to the 200 and above from the mid 90's to late 2000's, never had 1 failure, never smoked them due to distortion like todays garbage. SOME OF THE BEST MADE AMPS OF ALL TIME.

I had one of these back in the late 90's. Bought it off a guy in high school for $150. I wouldn't pay $500 for it. It was more powerful than what it was rated at but it wasn't really bang for the buck compared to some of the Pioneer amps and Kicker, Soudstream, or Lanzar amps of the times. I ran a 12" Kicker Comp sub in a ported box with this amp bridged 2-ohm mono and it hit pretty good. I had 4 gauge with a circuit breaker ran back to a distribution box in the trunk and put two 8 GA power and ground into the amp. Had a Kenwood eXcelon CD player with 4v preamp outputs. Amp would get hot enough to fry eggs, but I don't remember it ever going into thermal protection like some of my other amps did.

those mid 90s amps were powerhouses. I miss my Memphis 1000d.

Ahhhh the good ole days🤤 I had the punch 200 and man oh man I loved it....I have a BP JBL 1200.1 that they don't make anymore I have had it since 07 and have blown a pair of 15" kicker L5's and a pair of 15"L7's needles to say I hate sqaures lol the amp still beats hard AF currently pumping 4 kicker comp 12's definitely one of my favorite amps ever✌🏽

I had a Punch 200 back in the day with 2 kicker comp 15's. That was the first year they came out with the inverted dust caps.

I remember how they used to send a printout of that amp's performance, and that always struck me as a quality product. The weight and aesthetic also made me think it was built with quality in mind, they were a nice looking amp. Sadly the only one that I ever owned was the Santa Ana and it developed a problem with one of the channels and got hotter than a frying pan. One thing I didn't like about those early amps was the crossover setup, I thought that circuit board setup was a half ass attempt to integrate a crossover because it was over looked in the initial design. I just never heard a system with Fosgate amps that I was overly impressed with. I never really thought it was the amp, though. I always felt like they weren't being utilized properly along with poor enclosure designs, leading to a muddy and sloppy sound. All in all, I think Fosgate had it right long before a lot of other companies.

2 years ago, I picked up 2 of these, at a local thrift store. The couole that owns the thrift shop, buys out alot of storage units, and i gave them my number, years ago. They call me when they get any audio in their store. Both had one end cap missing on each. Also, one worked perfectly fine and was nice after cleaning. The other powered on, but had some issues. It needed caps, as they were swelled. Recapped the bad one, and it runs my wife's components in both front and rear doors, in her suv and sounds as good as it did new. Threw the other on ebay, with both end caps. Kinda wished I would have kept both.

A friend of mine had the 100x2 running 4 x 12s in free air in a sedan back in the 90s. Install was a bit dodgy because they removed half of his parcel tray to fit the subs but it bumped hard.

Amps back then had incredible damping factors. Damping factor basically boils down to ability to control the speakers.

One of the best amps I ever had.

I had the 500 amp just sold it along with two same 15-in subwoofers Rf. I regret selling it now. If I would have kept it it would have just been for looks because it suck so bad at pushing anything nowadays. The Rockford fosgate 15s had the tiniest magnet ever. But it worked perfectly with those. I sold the amp and the speakers for like 160 bucks. I bet if I waited about 5 more years I could have got more money out of it. But it's all good the guy was happy about he probably wanted to keep it as a collection.
