Used Roverbreakers, cost me £75, though just read another post (can't remember which forum), somebody else also got a sub from Roverbreakers for £50!JohnFol said:Hi Grendel, which breakers did you use?
You need to link the head unit via phono plugs to the amp, then wire the amp to the sub with ordinary speaker cable. You'll also need to run a fused power supply direct from the battery to power the amp. I bought an amp wiring kit from Halfords (£25), contains everything you need to rig up the system.Also, how do you get the signal to the sub? Does the kit come with a different loom / amplifiers?
PS Is that a Marillion reference in your name?
Mike, if the grommet is there you can't really miss it. It'll be in the centre of the panel and is about 2 inches wide, if you pop it out the sponge above it (under the parcel shelf) also has a hole cut in it the same size, presumably to suit the sub port.Mike VVC said:Will keep an eye out for reports on how you HK sub sounds (what size is that?) & check my boot to see if the underside of the shelf has a grommet in it.
I have a factory-fitted Kenwood in my ZT, that has the phono (sometimes called RCA jacks) on the rear of the unit. It's those you need to connect to the sub input with suitable connecting cable.JohnFol said:PS Can I presume that when you talk about phono connectors from the HU, you are taking about an after market unit.
Grendel said:Just done mine too, had to use a couple of nuts & bolts to mount the thing as I couldn't get hold of the proper fixings anywhere (though my local MG dealer said they could probably order some in).
Haven't yet cut out the hole in the parcel shelf, wanted to hear the effect in the car without. It's kinda hard to tell, there's definitely an improvement in the low end frequencies (need to fine tune the amp settings), and the parcel shelf doesn't vibrate with, basically, the sound from the sub effectively banging right against it.
I'll probably end up cutting the hole once I've got hold of something suitable to cover it with, and see if that improves the sound even more, but overall I'm fairly happy with the improved tones at the moment.
Oh and by the way, if anyone is doing something similar and buys an amp wiring kit, make sure the kit has plenty of cable! I bought a kit from Halfords which had 5 metres of power cable, which I thought would be plenty. Turns out with the route I had to take with the wiring it was just barely enough, ideally would have liked an extra couple of feet but it's in anyway.
