The trouble started on a busy arrival into ZZZ trying to comply with approach's request to descend over 2;000 FPM for a crossing altitude of 11;000 [feet] at ZZZZZ from 17;000 [feet] at that point the trim actuator failed trying to comply. At that point it caused a warning horn affecting the ability to hear well in the cockpit. I missed a frequency. I heard and read back XXX.XX but I programed XXX.XY. After getting on XXX.XX I was given what I though was 2;000 [feet] and read back 2;000 [feet]. It was really 2;600 [feet]. I descended to 2100 as approach was clearing me for the approach and caught the low altitude. Approach told me low altitude alert and to maintain 2;600 [feet] until established on the localizer. I immediately climbed to 2;600 [feet]and joined the localizer.
