Excellent value for money (I have 2 sub for under 600 €)
they turn with 1 amp RMS 2X500W 8oms, 2 sats Wharfedale 250 w rms are connected to it (thus 4oms)
for my usefulness there are extras and yes I would do this choice <img class="smiley" src="/images/audiofanzine/interface/smileys/icon_wink.gif" alt="" />
