Distribution blocks

[LongThrow]

I just ordered a PPI 650.1, says It'll do 650 @ 2 ohms to power 2 JBL GT5s in a sealed box. Dad a strict budget of $300 and had some good advice on getting a cheap system threw together quickly. I have 4g CCA KnuK power and ground, with KnuK RCAs and dbLink distroblocks. I also have a Jensen DUBA4100 4 channel to power my speakers (I added rear fill in my rear deck, gonna run it like this until I can get some powerful components and leave the rearfill alone) Amp specs say it pushes 70w @ 4 x 4ch and 10 @ 2 x 4ch.

I was wonder, if I could run true 4g to a distro block, reduce down to true 8g to my sub amp, and 8g to my door speaker amp. I know the Jensen will be fine on 8g, but I'm wondering if I'll have any problems running my sub amp. Will the 8g suffice?

ALSO

My DUB amp has a pre-amp output, to daisy chain another amp. I have front preout from my headunit, going to channel 1 and 2 of my amp. And im using the pre-amp output to daisy chain THE SAME AMP, but to channel 3 and 4.

Will running RCA Y cable from my front RCA output, to connect to a 4 channel cause audio loss? Or cause some sort of problem SQ wise? My headunit only has a sub out and front out, could I use that front out, and use a splitter to connect two different RCAs to the same output to run channels 1&2 with channels 3&4?

was going to use this, one side of the RCA to this splitter, the other side of the RCA to ANOTHER splitter.

the distance from the distribution to the amp is so short that you shouldn't experience any problems but better safe than sorry. there is no such thing as overkill though so if you used a dist block that split 4ga into 4ga that would be even better. i also see in your sig that you're running CCA wire, upgrade that to OFC as CCA has a much higher resistance.

Thanks for the reply.

I was told OFC is just a marketing gimmick. 99.90% rated for CCA, and 99.95% for OFC.

What is OFC and why should I buy it?

ofc is not a marketing gimmick, as soon as you feel the difference in weight and quality of the wire you'll never go back. cca corrodes over time, i had to constantly check my connections.

hundredths of a percent dont sound like much, but you do realize there's tremendous difference in "virgin" (i.e. high purity 99.99...) vs non virgin (less purity) lead?

4ga ofc is cheap as hell. i have some nice voltmeter distros and rca y splitters i can sell you cheap just let me know what you need. i dont have any ofc 4 ga besides small pieces but i can probably get some, if you just want cheap ill give you some cca wire free if it fits in the package with the other stuff

you'll need to get ring terminals and all that stuff still fyi

if the amp takes 4ga, give it 4ga, if it takes 8 ga, give it 8ga. i have a cheaper 4ga in to 4x8ga out voltmeter distro as well

i see, thanks for the info.

As per my knowledge the distance from the distribution to the amp is so short that you shouldn't experience any problems.

Also there is no such thing as overkill though so if you used a dist block that split 4ga into 4ga that would be even better.

And i have seen in your sig that you're running CCA wire, upgrade that to OFC as CCA has a much higher resistance.
