What speakers (two 6x9 and two 6.5in) would you recommend to be used with this amp?

Asked by: rando1
The GT7-6 (6-1/2&rdquo;) and the GT7-96 (6&rdquo;x9&rdquo;) can handle 50W and 70W of amplifier power at 4-ohms respectively. The GTR-104 is a 4-channel amplifier that can accommodate both pairs of the GT7&rsquo;s that can drive up to 100W per channel @ 4-ohms.

Hi I'm looking to install this bluetooth amp with 2 front speaker and 2 rear speakers into my classic car and was wondering what speakers you would recommend for the best sound? Also, what size is the dash mounted control unit?

Asked by: SimonC
Hi Simon, We can't recommend speakers, this is something you will have to find out with the information from the manual of the amplifier: GTR-104 100W x 4, &le;0.1% THD+N @4ohm 120W x 4, &le;0.1% THD+N @2ohm Above shows the output power for the amplifier, and you should choose your speakers so they will match this power ( especially the resistance of the speakers ) The size of the dash mounted controls, this is 110mm x 48mm on the front. If you need to cut out room to fit it somewhere, the cutout needs to be 93mm x 34mm If you require further information, please contact us on customer.support@harman.com

How does this work with an existing aftermarket head unit since it requires it's own control? Does the control unit it includes have FM capabilities?

Asked by: Bmann
This will work well with existing aftermarket head-units since this will not take over the function of a head unit and will only act as a controller for the amplifier. The GTR-104's controller does not have tuner capabilities and only can accept sources via Bluetooth.
