Yay. After lots of toil and trouble, I have a Highline stereo, wired to an aftermarket amp, hitting up my new sub in the back cargo pod, tuned in to the Grom unit I've had sitting around for a year, and the noise it all makes is PHE-NOM-ENAL.

Many thanks go to Joemamma. For phone, text, pm and email support. Convincing me I knew more than I thought I did, and I wasn't going to blow something up.

And thanks to Paul G and an extra speaker harness I can pull it all out if I want and everything is back to stock.

Just need to tidy up a few loose ends! Route a couple more cables! Solder the final connections... Ie. Fit it.





I've tentatively played with the amp settings, but would like to know what I am actually doing before turning things too far. Anyone know of a good amp tuning link? I've worked out input sensitivity, but am not sure how much I should be pushing that.

There are also hi and lo frequencies to set.

The line output converters also have a gain setting, should I play with that etc?

Want to be sure I'm getting the best sound possible, and doing the right thing by the amp.

Now to get it all back together so I can convince the missus "it's just that new head unit. It's much better."

 

Got the amp squared away.





Under passenger seat, as far forwards as possible, so the rear passenger has less chance of kicking it.

Head unit all soldered up and tucked away. Still works!

Doesnt quite push all the back in the slot yet. Too much stuff in there. Need a slight reshuffle.
