Help with AWG and two amps on distribution block

[Riotralph]

I'm planning a fairly simple two-amp setup, nothing over the top just something better than my stock.
I currently have:
- Kicker Key 200.4 (50w RMS x 4)... comes with manual that recommends 14awg wire and has a harness with two 14awg wires on it soldered together for power
- Blaupunkt active GTHS131 subwoofer for under the seat (120w RMS, peak 200w)
- amp wiring kit 4awg and another 8awg
- stinger 1 4awg in, 2 8awg out distribution block
- power wire runs are <=8ft from battery/distribution block

Plan was to have the 4awg from the battery to the Stinger block then split to 2 8awg to the amps
Problem, harness on the kicker has two 14awg power wires soldered together.
Question, can I solder/butt connect the one 8awg to the dual-14awg into the Kicker with not too many worries?

The amp is just 2 amps in one case
That's why the power and ground wires are separate but then soldered together
Yes you can connect them to one run of 8 gauge
Same with the ground.
Don't forget about the fuses.
How are you running a signal?
Do you have an aftermarket HU that has RCA outs on it or are you going to keep your stock HU and run a LOC

Signal highs through speakers for the signal and factory HU. For the power 14awg tiein to 8awg would you twist and pop on a terminal connector or solder?

I like using these for splicing oddball sizes

. Not permanent but a solid connection.

1aespinoza thanks for the advice, my local HD had the 14AWG to 8AWG splice with shrink! Perfect

I personally prefer to solder and heat shrink
