I am looking into possibly picking one of the amps up The Taramps HV 12k along with the DS 1200 x4 ch. and maybe 1 or 2 DS 440x4. Any experiences with any of these amps of what they like or dislike about any listed? Anyone running the HV 12k? I"ll have the battery bank to run all 4 if needed and an extra HO Alt if needed. Thanks for any information and experiencing.
