On the hartke HA 5000 bass head. It is 500 watts (250 per side) mono @ 4 ohms, but i was wondering. If you have 2 8 ohm cabs and you run the head in biamp mode, will it give you the full 500 watts this way??? Also, if i were to buy the hartke 3500 and then buy a power amp at a later dat, is there any way to then biamp the system? Thanks Graham
I don't think so. You'll need 4 ohms per side to get full output. Just buy 4 ohm cabs. As far as bi-amping with a separate power amp, a seperate crossover may do what your looking for. Dave
The Hartke 5000 is a dual mono amp (one preamp channel in to two separate power channels). The Biamping feature merely sends the lows to one channel and the highs to the other. Running in full mode both channels get the same signal. Either way, with two 8 ohm cabs you will get 170 watts a side, or 340 in total. The 3500 is a single channel amp. 350 watts @ 4 ohms, 240 @ 8 ohms. No built in biamping features, as it only has the one channel. As GMan said, you would need to buy a crossover as well as power amp if you wanted to biamp the 3500.
