Hi I have installed today the GTO509C speaker on one side of the car and i am dissapointed , the old original Mazda factory speakers have better quality. It is because they have 3 Ohm Impedance and the radio has 4 Ohm?

I am connecting GTO609c with an amp. Should I use the amp high pass feature to adjust the frequency or just full pass to the component crossover?

Asked by: cb85
Since the GTO609C has its own crossover, sending full-range signal or only those that the speaker will play will not make much of a difference with the speaker. It would help the amplifier, less strain on the amp, if you set its high-pass to only send the signals within the GTO609C’s frequency.

what amp should match with this speaker, also for gto609c. it is any difference in sound quality between gtr 104 and club 704 or look for gto 804ez

Asked by: FZRemover
The best way to do this is to look at each amplifier’s specifications: GTO 804EZ - 80W RMS x 4 channels, <1.0% THD+N @ 4-ohms GTR 104 - 100W RMS x 4 channels, <0.1% THD+N @ 4-ohms CLUB 704 - 70W RMS x 4 channels, <1.0% THD+N @ 4-ohms The GTO 509C and 609C can handle 75W and 90W RMS respectively. All this tells us that the GTR 104 can provide the most power and the cleanest sound at high volumes (<0.1% THD vs <1.0% THD for the other two). With its gain adjustments, you are certain that you will not overpower your speakers (GTO 509C and 609C).

hello i want o ask or those GTO509C speakers would  fit at the back of BMW E60 2009 thanks

Asked by: neo 1986
Hi Thank you for the question. As far as I can see from the webpages that have information about which speakers fit which cars. The BMW E60 should contain 4" speakers. So it is no good to install 5" speakers. If you have other question, Please contact Customer help-desk.
