    Protection

    Protect the amp and your vehicle's electrical system from short circuit conditions with built-in fuse protection, along with overload, thermal and short circuit protection. A heavy duty aluminum alloy heatsink helps prevent any thermal issues.

    NACHTRAG:
    Das neu bestellte Gerät hatte nach kurzer Zeit den selben Defekt! Schaltet über Remoteleitung NICHT mehr ab. Es bleibt ebenfalls ständig eingeschalten und saugt die Batterie leer.

    Ich habe den Verstärker im Dez. 2019 bestellt und im Frühling 2020 zu Beginn der Motorradsaison hinter einer Motorrad-Fairing verbaut. Was mir schon bei Erhalt des Verstärkers auffiel war, dass zwei Schrauben der Abdeckplatte locker, bzw. deren Gewinde durchgedreht waren. Ich musste diese Schrauben durch größere ersetzen, da die Abdeckplatte dadurch locker war und schepperte. Was ich auch komisch fand war, dass eine der lockeren Schrauben ein Blechtreibegewinde und eine ein Feingewinde hatte. Ebenfalls waren die Halterungen der Kabelanschlüsse gebrochen. Ich denke die Schrauben dieser Halterungen wurden zu fest eingedreht und dadurch die Hülsen gesprengt. Im großen und ganzen eine sehr schlampige Verarbeitung, bei zumindest meinem Gerät. Der Verstärker wurde über die Remoteleitung, am Zündschloss, zum ein und ausschalten angeschlossen. Dies funktionierte auch etwa 4 Wochen tadellos, dann ließ sich der Verstärker nicht mehr über die Remoteleitung abschalten. Er blieb permanent an, auch nach abklemmen der Remoteleitung. Erst nach entfernen der Sicherung an der Hauptleitung ging er aus.
    Nach Reklamationsversuch durch einen sehr netten Amazonmitarbeiter direkt beim Lieferanten, erklärte sich dieser nicht bereit ein Ersatzgerät zu senden, mit der Begründung er hätte sein Lager in GB und es ginge aus diesem Grund nicht. Amazon nahm dann das Gerät anstandslos zurück und erstattete den Kaufpreis.
    Da ich jedoch an meinem Motorrad alles so verkabelt habe, dass die Anschlüsse und Kabel genau für den Pyle Verstärker passen, war ich gezwungen den Verstärker erneut zu bestellen und zwar um ein paar Euro teurer, da der Preis zwischenzeitlich gestiegen war. Und siehe da, dieses Gerät wurde in GB aufgegeben, wo vorher genau aus diesem Grund keine Ersatzlieferung möglich war.
    Angekommen ist dann ein Gerät das entweder ein Rückläufer, ein gebrauchtes, oder Reparaturgerät war.
    Die Verpackung war nicht Original verschlossen, die Siegel mit Tesastreifen zu geklebt und die Plastikhülle aufgerissen (siehe Bilder). Die Halterungen sind bei diesem Gerät ebenfalls gebrochen. Ich habe den Verstärker jetzt trotzdem verbaut, - er funktioniert zur Zeit. Noch einmal auf ein Tauschgerät zu warten war mir dann zu blöd. Jedenfalls würde ich diese Marke anhand der schlampigen Verarbeitung und der Tatsache, dass ich nach Neubestellung kein neues Gerät erhielt, hier nicht wieder kaufen. Mit dem Klang bin ich soweit zufrieden.
    Ob der Verstärker wirklich Wasserdicht ist wird sich weisen. Das Gehäuse ist nicht abgedichtet und hat sehr große Spaltmaße. Wasser wird hier ungehindert überall rein laufen.
