View Full Version : 5v preouts when amp says 4v max?

04-12-2010, 08:55 PM
my audiopipe 3k says it has a 4v max for the RCA outputs on the head unit i think. the head unit i was looking at has a 5v pre-out voltage and i was wondering if it would be okay to run it anyway. otherwise i can only find 2.5v preouts

Your 5v pre-outs put out maybe 3.5, your 4 volt pre outs mayve 2.75, and 2 volt...well thats a joke ha

isnt a line driver just extra distortion? lol never used one due to that belief.

my eclipse deck has 8v, ive ran quite a few amps with no issues ever. im pretty sure my kicker 2500 was 4 or 5v max

how about this JVC? 5v preouts for 150 shipped

Quite the opposite, so long as you don't buy a junk line driver. The boosted RCA voltage is used to keep amp gains turned down and lower the noise floor of the system.

ahh ive just seen the audiopipe line drivers and dont know about them

I wouldnt touch audiopipe line drivers. Look at an epicenter or something. The amp only says 4v because 90% of HUs have <4v preouts. Im running an 860mp with 6.5v on an amp that only goes to 4v, just sounds better, no problems really.
