    So, theoretically, say I have an amp head, that sounds great but woefully underpowered (50w!)... rather than lumber around a rack-mounted poweramp...is there any reason why you couldn't use a car audio amplifier rigged in the back of the head to serve as a slave? (the amp has a line out).

    There's no small form-factor poweramps around that are designed outside of the rack-enclosure parameters, and can be rather expensive. Car amps are often quite small and, once you've sorted a power adaptor to deliver the 12v DC it would expect, and made a couple of adaptor cables to connect...essentially you can have it all in one portable package.

    Thoughts?


    *EDIT as this was pointlessly ambiguous:


    I have a Traynor TS-50B that I need to be louder. I dont want to haul a whole seperate rack poweramp as Ive done that before and didnt like it. Does anyone know of a solution that I can mount inside the existing head (on the empty part at the bottom of the shell) that I can 'line in' for more power? Preferably +500w-ish. Nothing too expensive.

    Really, I just need a small poweramp.

    Thoughts?

  2. Someone with more experience will weight in on this but from my understanding watts are watts but car audio watts are used to process already compressed (or processed) signal like a fully mixed song vs an unprocessed instrument like a bass. That's just what I was told before regarding this subject.
     
  3. No point in even trying to adapt a car amp for bass use. Just buy a micro and use the power section.

    Any suggestions on economically priced micro's that would suit? Guess I'd be looking for 500w approx

    Why not just get a bass amp with more output? There are plenty of very good sounding micro bass heads to be had in this era.
    From what little I know of car audio, most amplifiers have a crossover to separate the bass from the mids and highs. This is exactly the reverse approach from what you would want to achieve.

  6. I have the Fender Rumble 500 watt head with a 2x8 cabinet. I was using an SVT with a 4x10. I love my little setup. Sounds great. VERY LIGHT and VERY PORTABLE!

  7. The power supply would be larger and heavier than the amp itself. It would require massive amounts of filtering on the D.C. line. Stuff made for cars is generally designed to run on a 13.8 volt D.C. not from a 12 volt wall wart, if that's what you had in mind. Even with an automotive alternator elctrical system which is A.C. the battery acts as a filter. Without the battery, you'd need some seriously large filter capacitors to keep the ripple (A.C.) on the D.C. line low enough so that you don't hear power line hum. Consider that you often see seriously large filter caps being used with these amps even in a car. The car battery also acts to keep the voltage at a constant level during peak usage. If the amp was not designed to run from an A.C. wall outlet, you could be disappointed with the performance. Part of what you pay for in a standard amp head is the power supply to run the amp properly.

    The amp in question is a Traynor TS-50B...which has a very particular sound that I like, but want louder




    This -----^ is exactly the kind of in-depth reasoning I needed to know why it probably wouldn't work.


    Looks like I gotta find a little class D amp with line in to rig into the back of the head

    The forum is filled with hundreds of threads on these heads. Shop used to save $$.

    Look at the Traynor SB500H as it might have a preamp and EQ closest to what you use.

    Huh? Do you mean that the ones that are available tend to be expensive? [​IMG]

    All of those suggestions are probably too large to squeeze into the existing head space, or are likely quite expensive. Also, none have a "power amp in"-type input.


    Yeah, think I got myself muddled up a bit there!

    Seems a shame to buy a whole amp (with preamp etc) just to use the power section...seems weird no-one just makes a little class D (or similar) poweramp!
     
  14. All they need is an FX loop

    Yeah? That's good. Never used an FX loop as I'm a tad 'old-school'...so never learnt about them

    OK, let's start at the beginning. What's your budget and what are your size constraints?

    Defining your goals better will always provide better results. If you had started this by saying "I have a Traynor TS-50B that has a unique sound I love, but want it louder. Ideally, the solution would fit in the empty part of the head (insert photo) and wouldn't be really expensive." You would get more concise answers to the question.

    What 50w amp do you already have?
    Is it a combo?
    Are you sure the great sound you amp has even comes from the preamp?

    Don't be afraid of the new micro amps. There are many available, you'll surely find one that you like the sound of.

    Size needs to be less than or equal to: 17" wide, 5" High and about 6-7" deep
    Budget I guess would be a few hundred bucks / couple of hundred pounds (I'm in the UK) but stretchable for the right thing

    True. I guess I was being ambiguous for no real reason. Apologies. Maybe I should start again!
