Now, the beauty of the T-Amp system is best expressed by the following simple pictogram:
* * Boss speakers
| Cable
0 T-Amp

• Ipod
Those T-Amps look great, but as dub says lots of people have pretty good hi-fis installed in their van already and just want to be able to run that without flattening the starter battery.
Also it's handy to have 240v to run things like hairdriers and rechargers for the AAs that the kids use in their Gameboys, etc.
