    Hello everybody..
    Last week i played with an Ampeg Portabass and i really liked it..it sounded good and pretty light rig...since i dont see myself in the next times affording EA stuff, this can be a good solution for me...but i have a question.
    The head output is rated at 250 W at 4 ohms and 150 at 8 ohms,which means that if i buy a 4 ohms speaker i will have 250 W..so far so good...the problem is with the combo amp.
    The combo output is rated exactly the same, 250 W at 4 ohms and 150 W at 8 ohms...
    So if i buy this combo and want to have 250 W what can i do??? Do i need an extra speaker for the 4 ohms load??
    Thanks in advance, probably the answer is pretty simple but i this is only my 3rd cup of coffe today and still cant get it..
    Thnaks a lot

    As far as I've read the manual(s), the internal speaker cab is 4 ohms already, so you can either use an external cab OR the internal one.
