Not to take anything away from Crutchfield, as I’ve had really positive experiences with them and found them very helpful and responsive.
That said, we have a really solid cadre of supporting vendors here on FRF. they’re spending time and effort answering questions on here, it’s at least worth a conversation.
My question is how hard is this all to DIY? I'm not an electrician by any means, but I am pretty handy - I've been building PC's for 20 years, know my way around wiring house stuff etc. I just never did any of this on a car before. Looking to save the $1k if I can...
Buy once, cry once. Go big, get extra of everything and yes, it can be done in the driveway. Count on battery home runs for power and ground, and have extra so you can make it fit properly.
Figure out how you will mount the amp(s) early. Make sure it will work. My very clever plan did not work out and I spent about 2.5 hours on mounting my amps correctly. FWIW, I failed to account for the change in available depth behind the seat as the seat is bottom is lowered from the up position.
Since you know PC’s and some house wiring, you know better than to severely bend, kink, knick, cut or otherwise compromise the conduit, but once you have connectivity, verify you have +12v and a good ground. Homeruns should take about 1-1.5 hours for an in the driveway install.
harnessing in the amp, mounting, probably an hour if your plan works out.
Once you have sound, you need to at least get it to “flat signal” to tune with. Once you’re at flat signal with gain set, you’re at least ok to listen to it and begin fine tuning. That part can take a while.
Whether this outlay is worth $1k to you, only you can answer. You build it, you own it. You farm it out, and there’s at least someone you can complain to when it doesn’t sound right.
I’m fairly handy with tools, so I did the install myself. So did a few of the rest of us. Lots of stuff on youtube as well.
good luck!
