running 2 amps

[88.4ageGT]

ino this a simple qestion but
if i wanna run two amps do i just split the rca cable then run one to each amp?

[soopachargen]

how many rca outputs does your headunit have??

[88.4ageGT]

it doesnt have any. i brought
a speaker wire to rca converter
and wanna run to 2 amps
one for a sub and one for speakers

[soopachargen]

in that case yep, just split the rca and run to each amp, you just wont have very good control with the headunit, but having no rcas you wouldnt have had to start with.

otherwise you could get two line level converters and run front speakers off the front speaker cables and the sub off the rears, that way you can tune it a bit with the fader control on the headunit

thanks
um next question can you explain whats the difference between a 1 channel amp and 2 channel?

[soopachargen]

each speaker runs off a channel, a one channel amp or mono amp in its most basic configuration will run a sub, a two channel amp will run a left and a right speaker, so you have a left channel and a right channel. With a four channel amp you have a front left, front right, rear left and rear right channel.

Hope this makes sense?

yea i get that
so the amp i have has this on it
speaker

+ - + -

so is that a 2 channel?
and which two of those four do i connect the sub to?

[soopachargen]

that would be a two channel amp

12volt direct current, as used in a car travels from positive to negative, so it runs from the + terminal of the amp, to the + terminal of the speaker, through the speaker's coil to the - terminal of the speaker, back to the - terminal of the amp.

What brand and model are your sub and amp? Most amps are bridgeable, which lets you run from the positive of the left amp channel to the sub and then to the negative of the right amp channel "bridging" the amp, this will give you more power into the sub.

[88.4ageGT]

ok so with that amp i could run 2 subs?

[soopachargen]

in theory you could run two subs off it, but I would guess that that amp wouldnt be putting out a huge amount of power, you are much better off running one sub with enough power than two subs underpowered

[88.4ageGT]

so if i wanna have 2 subs nd 4 speaker
i need
two 2 channels amps (for the subs)
and
a 4 channel amp (for the speakers)?

[soopachargen]

what gear do you already have??

[88.4ageGT]

2 channel amp
1 sub
4 speakers

[soopachargen]

what sort of amp and sub??

[88.4ageGT]

amp is lighting audio
is abit old thinking of replacing
and a 12inch fusion sub

[88.4ageGT]

is this what i use to split the rca

tip, buy a new headunit with sub control etc, theyre cheap as nowadays, get a d-class (1 channel) amp, you can run 2 subs off a decent amp

and just run ya speakers off that 2channel amp uve got, just bridge the 2 fronts together and rears together
