a little bit of an update, tried all the amps in different combinations and found that the alpine MRV-T802-dx was upsetting the MRV-F300s so went and bought a second hand MRV-T500.
so now have two v12s running my vibe s12 and Type S comps and its now kicking.
the mrv-t500 is running the sub (bridged) while the mrv-f300 is running the comps also in bridged mode for that extra bit of power.
happy days!!!
