Es lohnt sich!

Ich habe sie an den Sounddigital 800.4 Evo6 angeschlossen. Und ich bin mehr als zufrieden. Mitteltöner laut und auch präzise. Hochtöner brennen nicht in den Ohren, die sind laut und geben das, was sie sollen. Gut angelegtes Geld.

Laut ... einfach nur laut

Also ich sag es mal so... wenn man ein Lautes Kompo System sucht, mit noch sehr guten Klangeigenschaften.
Naja der sollte das T3 von Rockford nehmen.
Ich hatte viele Systeme verbaut und bin dann wieder zurück zum T3 und habe nun 3 verbaut... schön laut und sehr feiner Klang.

vibe powerbox65.4m v7 samen met quadlock connector besteld.

Levertijd prima in orde.

vibe powerbox65.4m v7 in mijn vrachtwagen Volvo Fmx 2024 gemonteerd met Quadlock.
Alleen plug and play super fantastisch systeem. Alles standaard op 12v geen omvormer of iets nodig.
In bouw tijd ongeveer 30 minuten.
Radio verwijderen connectors verbinden vibe powerbox65.4m v7 aansluiten.
Alle originele radio instellingen op nul of uit gezet. Volume op 3/4 langzaam de powerbox65.4m v7 open draaien en al het werk laten doen.
Perfect kristal helder geluid in combinatie met mijn Rockford t142 en Rockford p1650 speakers. De bass geluid is verbeterd maar voor echte diepe baas waar ik persoonlijk niet zo van ben heb je echt een externe subwoofer nodig.
Kortom een goede upgrade van je radiogeluid is gegarandeerd.

Masori was goed met de prijs, perfecte communicate met hun gehad. Een echte aanrader.
