Got an old RF Punch amp from a friend...

[CaptNKILL 10+ year member]

I don't know much about older equipment like this but a friend of mine desperately needed some cash so I bought his old Rockford Fosgate Punch 60x2 *****-ana amp. I have a Kicker zx200.2 powering my Eclipse SC6500 comps, and I guess it works fine but some things just never seemed right with it (serious lack of bass compared to stock speakers on HU and very low voltage readings) so I figured I'd give this thing a try. I haven't had a chance to test it on my system yet though.

After looking around the net a bit, it sounds like these things were pretty nice back in the day and people still like to use them.

What would you guys say something like this would be worth? It isn't in real great shape cosmetically, but it works fine. If it doesn't fix my mid bass problems and if I don't find another use for it right away I might try to sell it.

The specs from the manual I found online are attached.

Those were good amps, no idea what it would be worth though.

Most stock systems have decent midbass compared to aftermarket, generally it just takes more work to get really good midbass out of aftermarket. Sound deadening and making sure the door is sealed really really really well, or even building seperate enclosures for the midbasses are what it takes. An EQ might help you out also if your not using one.

Those were nice amps man, quite powerfull for the size...

if it is really nice you could probally get around $60 shipped for it....

Thanks guys. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

And trebor, I thought my doors were sealed alright but I don't know just how sealed they need to be. They have a steel panel on the inside of the doors which separates the interior from the outside layer of the door and the speaker mounts on that panel. I used a mounting bracket from Crutchfield (which I had to cut to fit) and I used some double sided weather seal strip around the edge of the bracket. There are some small rivet and clip holes in the metal panel though. I didn't think that this was enough to really mess up my sound but I guess its possible.

When I get some more time to mess with this I'll take some pics and post them here.

Have you guys ever heard of an amp putting out weak bass and midbass? The sound is there, but its just so quiet compared to my stock speakers, and those things are running on 22w and have a magnet that's barely larger than my tweeters. //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif

Very nice amps, I used to have one. I concur with the $60 part, maybe 50 depending on how tore up it looks....

 

[CaptNKILL 10+ year member]

So I guess $30 wasn't too bad then. I didn't desperately need the amp, but he definitely needed the cash, so I figured I'd help him out.

I didn't expect the thing to be worth much.

The paint is coming off of the heat shield in some places. If I ever use it I might just sand it and repaint it.

I wonder how those stack up to the Punch 40 DSM, punch 100 DSM; are they slightly newer than the dsm series?

I'm running a punch 100 DSM currently...it's on a dual 2 ohm wired in parallel - 1 ohm load - bridged //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif . These amps are highly underrated IMO. The punch 100 bridged like this can push the CVR10 i've got past it's mechanical limits without breaking a sweat...it's rated at 400w RMS, so i suspect this lowly '50w rms x 2 channels' amp is pushing around 600w. I've got a punch 60 DSM that performed amazingly well on an original 12w6v1 also. (so well that i picked up another one //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif). When you look at the cost for these amps used, it's really hard to justify buying the 'latest and greatest 500w amp' to push your subs.

A punch 100DSM is rated for 200RMS bridged into a 4ohm load. Typically though you could expect a brith sheet to show them making in the range of 300RMS bridged. There is no way it will push 600RMS @ 1ohm bridged for very long though. I call BS.

My 200DSM is rated for 400RMS and makes 534RMS according to its birth sheet. They are a great amp series, no reason to over exaggerate them though.

I pushed these things bridged into 3 ohm and occasional 2 ohm bridged loads back in the day and lost a few. 1 ohm bridged is a sure death sentence.

-1 reading comprehension - It's not running bridged to a four ohm load; it's running bridged to a one ohm load. No manufacturer ratings or birthsheets are going to show you that... I'd love to get my hands on a 200dsm. I think it would be positively monstrous when bridged down on a 1ohm load.

I re-clarified before you posted. I don't believe you. I am very well versed in RF products from beginning to ending to know that your scenario is far from reliably feasible.

You can type all you want, but I know you are a liar. I have seen too many go up in smoke in the early 90s this way.

LOL... wow dude, you're an arrogant ****er, aren't you?

Not only am I not lying, but my setup has been this way for over a year, and it plays more than an hour a day at high volumes with this configuration, and it has survived several 5+ hour road trips where i never turned the music down the entire way...in florida, in near 100 degree temperatures.

Before that, i had a punch 60 running bridged into a dual 6 ohm 12w6, thus a 3 ohm load, for several years without damaging the 60 either. Perhaps you clipped the shit out of the ones you and you ran back in the day and killed them, but mine aren't dying.

I've got a 120mm fan blowing over the amplifier (actually, it's pulling air over the punch 100 and blowing it across my mids/highs amp - an arc audio 4150xxk, otherwise nothing special.

I have ran many at 3ohm loads the same way(JL OS w6). Those were fine. I have seen WAY TOO MANY 2 ohm bridged loads fry the board on those amps beyond repair to believe your 1ohm daily BS. If it is wired at 1ohm, you aren't running it anywhere near full tilt and pulling 600 watts. Ol School RF is all I ran in the 90's. They can't handle that low of an impedance bridged daily at full boogie.

Like I said, type all you want. I don't believe, in fact I know those DSMs won't run reliably on 1ohm bridged.

 

[headless 10+ year member]

LOL, ok dude, believe whatever you want... i'll keep enjoying my setup configured as i said with a dual 2 ohm cvr wired in parallel and bridged to my punch 100. Like i said, the cvr is rated at 400w rms, and this can push it beyond it's limits without a problem.
