Hi guys,
Looking for a good line driver for my boat. I've got 7 amps I want to run in it and I don't think the head unit has enough voltage to run it all. Any suggestions?

RCA voltage is the same no matter how many amps. I have ran 6 amps at 4.8 volts out of the headunit and every amp had 4.8 volts in.

Not if your OEM or aftermarket headunits RCA voltage is really low and you want 4-5 volts.

The preamp input on most amps is 10-20k ohms, so you don't really lose voltage. I've run plenty of systems off 2v preamps with no problems.
