Rated 3 out of 5 by from Niet slecht, niet geweldig Ik heb deze 4"x6" speaker gekocht, omdat het de enige was die paste in mijn old-timer. Volgens de technische fiche zou de frequentie respons vrij goed zijn, maar nu ik hem hoor spelen (op Alpine radio met MosFet 4x45W) blijkt dat de basrespons maar mager is en het geluid toch wel wat vervormd. Kan ook moeilijk anders voor zo'n kleine speaker van deze prijsklasse, maar toch.

Rated 5 out of 5 by from Exactly what I expect from JBL Bought these a few weeks ago to replace the dash speakers in my 2000 Wrangler. Huge upgrade from factory, and a slight upgrade over the Kicker 4x6 speakers i had previously installed.

Positive and negative terminals on the speakers has standard differentiation. One with the thinner size is the negative and the thicker is the positive. Some differs in colors where Red is the positive pole and Black is the negative pole.

Will 3ohms speakers work with any type of amp?

Asked by: Auggie
All our full range car amplifiers are rated to safely handle down to a 2-ohm load speaker. This may differ with other manufacturers.

I bought these speakers (GTO 6429) along with GTO 629. Looking for an amplifier that I could put on both pairs of speakers. Would like to keep it JBL; what would you suggest?

Asked by: jimofed
The GTO 6429 and the 629 can handle 50W and 125W of amplifier power respectively. Any amplifier that can drive this much power at 4-ohms would be recommended and should work fine. An example will be the GTR-104, this is a 4-channel amplifier that can accommodate both pairs of the GTO’s that can drive up to 100W per channel @ 4-ohms.
