Quick Pre amp voltage ??s

[chevyboy23]

k so im getting ready to hook up my subs and sub amp today and just wanna make sure i can run this safely without risking damage to any components ... diamond audio d5 1200.1..4 12 cvr d2(1ohm load )..real ? is can the amp which i believe is rated to 5vlts handle the advertised output of my clarion esq746 which i believe is 7 volts (rms)..not sure about stuff like this and just want t know if i need to do anything special to get slumppin today or if i can continue as normal everyday install..want to bump today so quick replies r greatly appreciated..thanks in advance..

The amp and headunit watts rms are not related in anyway.

The pre-amp of a headunit is the max voltage that it gives out to the rca jacks.

2+ volts is good enough for any amp. If you have a 1 ohm amplifier then the sub should be able match together.

i get all that but my eq puts out 7 volts is that a problem?

look at the specs for the amp it will tell you what input volts it takes. some amps are not rated for high (7 volts ) input.

what are the # on the amp on the gain knob ?

Shouldn't be a problem.

The EQ has a volume -- which is basically a control of its output voltage.

I would be surprised, even with the vol set at max if the output voltage is too much.

Besides "too much" wouldn't really be a problem. It just means you'd get a little clipping at high volume.

Compare it to the common idiot that cranks the gain up to 0.2v for an HU with 2v outputs.

7 vs 5 would be a slight overlap - not a big problem at all.

What I would probably do is set the amp gain at 5v and the x/o volume at min. Then instead of increasing the gain to get to your target output voltage, I'd turn up the x/o volume.
