okay so with my stereo i basically have two sub outs, if i were to use both would i get any better signal or anything? (y splitter to a signal rca cable to the amp) like double the signal in or since its a mono amp would it matteR?

 

not quite double the signal because thats not really how it works but yes using both on a y splitter is better then using one. It would be optimal to use both of them on their own rca wire going to both the rca inputs on the amp

 

okay, thanks!

 

depending on what head unit your using, the pre outs have a set line voltage, so by spliting them your really doing nothing, stick with one set of pre outs, your best bet to help with line distortion would be get some premium rca cables for your amp, and as well check out the amps specs for optimum tuning, the manufacturer web page should have them or the manual will have some briefe info on it

 

well right now i have the headunit with 1 sub out, and at the amp i split it into two channels, if i split from the headunit and only went in one channel at the amp could i theoretically get better bump at lower volumes?

 

wait what?

If you have a single female RCA for the sub and 2 RCA inputs on the amp your going to want to use a y splitter somewhere along the line but it wouldn't matter if you do it at the hu or amp (i would say do it at the amp so its easier and a single rca has a less of a chance of having something break physically)

If you have 2 female RCAs for the sub then you want to run a set of RCAs all the way to the back for both RCA inputs.

If you have a 2 channel amp bridged you MUST use both inputs on the amp. a mono amp would ~ half power on a single RCA input but a 2 channel needs both to run correctly bridged

 

its a mono amp

on my headunit there are 6 preamp outs

2 front, 2 back, 1 center, 1 sub

the sub was weak, so im using the 2 front for the component speakers and the amp for the 4 speakers copies the signal to the back (3/4 channel)

so 2 out of the 6 are used... i don't have a center speaker, and the sub is weak, so 4 out of the 6 are used, the last two are the rear left/rear right

from there i have a channel (only left or only right, one physical rca) running from the left rear output to the sub amp where i split it right before the amp into two channels

 

run both rear left and right direct into the amp no y splitter you should notice a bit of a difference

 

how much bass i would get on 26 is not what i get on about 22/20... so yes it made a good difference, like always thanks empj
