Re: Carver TFM-25 with SDA SRS 1.2
Oh you HAD TO KNOW if I was around I would jump in on this thread.
The TFM-45 would definitely be a better match for those bigguns. OR if you still wanted to stay with Carver, try Sunfire amps.
Ivan aka @pitdogg2 knows exactly what he is talking about though.
I had TFM-45 amps driving my old pin/blade SDA-1C's that @lightman1 has now.
I currently have yet another Sunfire Cinema Grand Signature driving my SDA-SRS 3.1TL's and making wonderful sounds.
P.S. The oldest Carver amps-that being the M series-were not common grounded between the two channels. The TFM series which replaced them are common grounded.
I still have a letter from Bob Carver himself about my first SDA-1B's and a Carver M-400t.

Re: Post a picture.....any picture...part deux...
Rat rod kewl!

And on another car note...
"Hemi Under Glass but now we've got a Boss In The A**????
The Secret Mid-Engine Mustang: Ford’s Hidden Boss
In 1969, Ford quietly began working on a wild idea — something almost no one outside the inner circle knew about.
Codename: The LID Project (Low Investment Drivetrain)
Mission: Build a mid-engine Mustang using the monstrous Boss 429 V8.
At the time, the Boss 429 was a street legend. But on the track, its massive front-end weight threw off handling — a 60/40 front-heavy balance wasn’t ideal. So Ford engineers, alongside Kar Kraft, asked: what if we put the engine in the middle?
The result was a one-off prototype: a mid-engine Boss 429 Mustang unlike anything Detroit had seen. With the engine now behind the seats and ahead of the rear axle, weight distribution flipped to 40/60 — a dramatic shift. Wheelspin dropped, handling improved, and the project showed promise.
But the gains weren’t enough to justify mass production. The project was shelved. The prototype vanished. Some say it was destroyed. Others believe it's still out there — hidden away, waiting to be discovered."

Re: Out of the game for years and in need of a new amp for my SDA SRS speakers.
Other than changing the tweeters there are quite a number of changes to the crossover involving resistors, caps and inductors. The schematics are posted on the forum for your viewing.

Re: Out of the game for years and in need of a new amp for my SDA SRS speakers.
Correct, updating the crossovers and replacing the tweeters as stated above. In addition, the negative wire that attaches to each tweeter will need the quick connect changed to a larger size to fit on the tweeter post since it is larger than the positive. Then you'll need a Molex pin removal tool to reverse the polarity for each tweeter where the Molex connector attaches to the crossover board.
If you order the tweeters through Polk mention that you are a forum member and I believe you get a discount and free shipping but don't quote me on that as it's been a long time since I ordered from them. Part number for the tweeter is RD0-198-1 if ordered through Polk. That's a zero, not an ohh. If Polk no longer sells the tweeters, Midwest Speaker sells them and part number is RD0198-1
