Product Q&A

Can I use just a 4 ohm speaker with this amplifier?

Asked by: jojoruiz
Yes you can use it with a 4 ohm sub but you will only get from 150 to 200

Hey would this amplifier work well with the GT-12BP? I'm looking to upgrade my audio in my car just like a nice sounding bass. Thank you

Asked by: tytheguy
Yes. Our JBL GT-12BP will be compatible with the JBL Stage Amplifier A3001. As the GT-12BP has a power handling of 300W RMS, 1200W peak at 4 ohms and the Stage A3001 provides 300W power at 2 ohms.

Good day... It states in the manual that the A3001 does 300W RMS @ 2ohm & that it has no 4ohm rating - what wattage am I to expect if my subs\coils are say 3ohm when wired in parallel? What will happen if I use coils\subs @ 5 or 7 ohm? Thanks...
