Sound quality at a reasonable volume.

So, a bloke on the internet on a budget, vs the R&D department of a large corporation that specialises in musical equipment.
Good luck

I would have thought an opinionated wanker like yourself would be able to solve the problem. Thanks for the good luck message though

this would be fine: http://cgi.ebay.co.uk/2011-New-Vers...ltDomain_0&hash=item43a536ee24#ht_6634wt_1226 and it's less than 20 quid delivered.

(although that one doesn't have a power lead - they're 23 quid with power leads. also, it auto cuts out above 13.8v which means charging from solar could be a problem if ur planning on that)
This is the model a lot of the diy audio forum peeps use: http://cgi.ebay.co.uk/Lepai-TRIPATH...Amplifiers&hash=item414eea6c5a#ht_3351wt_1030
Miine's slightly smaller and has no tone controls.

you can't play a bass guitar through a hifi-style amp. it will sound awful and possibly blow up. if you combined it with that amp with some cheap £10 speakers it would last about 3 seconds if you plugged a bass guitar in to it. seriously for a bass guitar yuo will be better off with a purpose built thing, people have spent many decades making them right. playing recorded, mastered music through an ampis an entirely different thing to an uncompressed bass guitar signal.

Not sure about the bass amp stuff myself, but I can't see how it would be that different tbh. Just a quick check of portable bass amps shows a fair few are just a 8" speaker in a box with a 10-30w amp and a battery. Unless you spend a fortune you don't get much for your money.
I've seen decent celestion 8" bass drivers for 20 quid.
If I were junglevip I'd look at diyaudio or speakerplan forums for someone who's done it before. Might need some sort of filter or input sensitivity hack I guess. I doubt it's that hard.

Another impedance/wiring question
What happens if I connect both speaker outputs from an amp to a single speaker?

Don't, is the short answer.

Why would you want to?
the dynamic and frequency range from an unbalanced bass guitar is far bigger than the signal from a cd or whatever... it requires a far more heavy duty amp and speakers.
and yes of course portable bass amps are a speaker and and amp in a box, what else would they be?

I was wondering if you can use both channels of one amp to drive one speaker with twice the power

To 'double' the power, I'd guess.

If the amp has a "bridged" mode, you can, otherwise no.

What's different about bass amps?
As far as I've read else where there's nothing particularly special about bass guitar amps.

ah, ok.

That article wikipedia article confused me somewhat. When it talks about two amps in bridged mode making one mono amp, it's talking about two channels from a stereo amp, right? (even if they've had a mono input and therefore have the same output)

Just read up and it seems t-amps are already bridged internally, meaning you can't bridge them again. Not sure of the details.

You can however parallel more than one t_amp into a given speaker. Apparently.
it was right there in my post, they need to be much more heavy duty, particularly bass amps because of the extra work the low frequencies make. they also need to be able to cope with much greater volume peaks as well as the greater frequency range.
where have you read anywhere that there is nothing special about bass or guitar amps? i'd be surprised if you could find a single mention anywhere of anyone using a hifi amp for a guitar or bass without bad results. they are NOT interchangeable, where can you find anyone saying they are?

I have a large bass guitar amp that I never use. Can I build that into a portable system somehow?

Yeah, a stereo amp is just two mono ones in the same box.
you can easily run a cd player through a bass amp without harming anything, the problem then will be that it sounds rubbish, as the amp has been designed to make a bass guitar sound good, not to provide the flat signal response that is the best for reproducing recorded music. would probably sound good if you played some kind of dub through it though. for best results split the signal with a crossover, run the bass part through the bass amp and the mid/treble through a hi fi.

Well I'm thinking of a multi speaker system with the integral bass amp being used in conjunction with a mid and high speaker(s). Will be used to playing pre recorded music, I ain't inviting people to the woods to hear my terrible bass guitar playing... Just a thought as it just sits there gathering dust. Must be an 18 inch woofer on the thing.
it wouldn't do any harm for sure, i've done it, used a standalone bass amp to add a bit of power to a little PA system for a dj night. it is not hifi at all but it sounds quite cool in a way, in the same way that dub sound systems sound quirky and the speakers colour the music a lot.
just take a line out direct from the mixer and put it in to the input of the bass amp.
