I currently am running 3 of these audio control line drivers and the pros-able to gain a ridiculous amousnt of signal output 9.5 rms I also like the voltage indicater lights and you are able to take the cover off and switch the jumper pins inside. Be careful when setting this line driver it is very capable of doing damage to audio equipment be sure to set it properly. Cons-really made for one amp at a time but you can most likely split a 9.5 volt signal with ease. make sure a good head unit is used to have a better chance of getting a 9.5 volt signal.

This thing works great, had it hooked to 2 12" kicker comps and a Kicker10ZX300.1 pushed my amp hard, clean clear. I had this bass note before purchase, that when bass hit you could tell that i had a box, it didnt sound like bass should sound, after, it sounded perfect. Nice and loud, bass knob down to 1/2 and pushed it like if i was maxxedout on the bass knob. shock my truck, and was heard from a distance, not like before install.
