Pre out and 6 channel amp help

[HickRm]

I have a head unit with only 1 pre out but I am thinking of buying a 6 channel amplifier, which has 3.

my thought was to run a pair of front and back speakers and then bridge the last two channels for my sub. with my head unit only having 1 pre out does this mean that this wouldnt work

thanks for your help

hi, you could use phono splitters but that means you cant run any high pass or low pass settings on the headunit, it can be done but it would be better to change for a better spec headunit to suit this type of install

basically here is my set up atm:

Front I have:

JL C2 650x coaxials

Back I have:

JL Audio TR525 coaxials

sub and amp is:

JL Audio 12” sub 12W0-4
JL Audio E1200 Amp


what I was looking at doing is losing the E1200 Amp in favour of a JL Audio E6450 Amp. And upgrading the headunit later on. I just want clearer, crisp sound when I turn up the music

so that would be amping front and rear coxials then bridging the last two channels for my sub. I have a 4 gauge wiring kit already which is the minimum i need to run the JL Audio E6450 Amp

would you recommend another way to amp the speakers?

hi, erm i would just keep the e1200 for the sub, then use the pre-out off that amp into a 4ch amp to run the front and rear speakers, the e6450 is only about 45 watts i think per channel.

the speakers are rated between 15 - 100 watts per channel and 15 - 75 watts per channel which means 45 is about in the middle and defiantly better than being ran off my headunit. with the last two channels bridged it should be 150 watts which would power the sub.

I just wondered if it would be a clear difference to my system doing this (when i have a headunit that has 3 preouts)

i was just thinking if you went bigger you will have the power for more speakers, but your amp would run your sub at 2ohms 200w rms, and 45w rms at 4ohms for the mid/high range isnt alot but yes better than ran off the headunit and you could get a decent 4ch that runs 100w rms per channel easy
but when you change the headunit you will be able to adjust and fine tune the sound to suit your speakers but means running 3sets of phono's but worth it.

but upto you what i would do is: headunit, e1200, 4channel
