Ο SP 4.900 είναι ο πρώτος ενισχυτής Hertz που διαθέτει την ανανεωμένη βαθμίδα εξόδου Hertz ADC (Advanced D-Class), που φτάνει έως και το 85% απόδοση και προσφέρει εντυπωσιακή βαθμολογία ισχύος 160 x 4 (4Ω) W RMS ή 500 W x 2 (4Ω) W RMS όταν γεφυρώνεται, με εξαιρετικά συμπαγές μέγεθος 211,6 (8,3) x 130 (5,1) mm (ίντσες). Όντας εξαιρετικά συμπαγής με εντυπωσιακή ισχύ, το SP 4.900 είναι η ιδανική επιλογή για εφαρμογή μοτοσυκλέτας και για κάτω από το κάθισμα σε σπορ αυτοκίνητα και εγκαταστάσεις πίσω από τα καθίσματα σε φορτηγά.
