is that any good? its £150 for it and im considering getting 2.

basically need an amp to power front L, front R, rear L, Rear R, Centrex2 and sub(2 channels bridged).

RMS power (4 ohms) 4x50W ... for 150 quid? Sounds a bit steep but i dont know the amp either, have another look about. The s/n is reasonable but the low frequency response of 20Hz is a bit on the high side, id expect 10hz for that money

Btw, they are listed in the french section of the blaupunkt site- perhaps CAD imported them?

20hz is on the high side???
the human ear is not capeable of hearing anything below 20hz or above 20khz.

Can't hear it, but you can feel it.

How much is that amp is US currency?

If you're considering a sub that 10hz will make a difference.

That's a four channel amp. And not one designed (Very well) to take a sub. If you want one that can do all that, you'd need like, an MTX. Or buy a 5 or 6 channel amplifier.

20k is not high. That's normal.

If you want to use it for a sub, however, as said, 20 Hz is on the high side for a sub, considering the lowpass filter goes down to 40Hz..

Going with a 4 channel is not going to make you happy.

You need at least a 5 or 6 channel amp or go with seperate amps.

Seperates give you the most flexibility. But there is enough to be said about haveing everything wired to a single amp.
