Hi guys got a quick question, i just bought a sub with amp and got main leads but it doesnt have a remote lead and wonder if original headunit has a connection for it

I've recently put one in mine, but replaced the headunit for a single din pioneer as the stock headunit (swing) was no good in my opinion. Doesn't have any pre-outs so you'd have to use existing speaker output and line level adapter to connect to the amplifier.

Far easier to replace the headunit for one that does the lot for you.

Just done the same last night as it had weird connection to the unit it self and original unit didnt hsve aux connections to run it to sub
