Hey Guys,

So I had my X converted to LPG at the weekend and the installers had to take out my factory subwoofer to put the air compressor pump in that right hand cupboard.

Not that the OEM subwoofer gave that much bass but now its soo bad. I cannot stand the sound of no bass so I've treated myself to an:

• "Orion HCCA 12.2 subwoofer" (HCCA122 (12inch Dual 2ohm) - Orion Card Audio)

and I wanted to go for the "Orion HCCA 5000 amp" to match but haven't got the funds at the moment so I have an old "JL Audio 1000/v2 Monoblock Class D" (1000/1v2 - Car Audio - Amplifiers - Slash v2 - JL Audio) lying around so I plan on using that for the time being just need to get the connections setup.

I know this has probably been asked a million times and I have read the How To's but I seem to read different install information depending on each person and which factory options they have.

So from factory I have:

• Nav 16:9

• DSP amp Upgrade

• Professional Hifi Upgrade (Extra speakers in rear doors and factory sub in boot cupboard)

I think I'm OK with running the with running the power from the battery I take its just Black to negative and Red to positive right??

I don't know where to get the inputs for the line input amplifier. Here are the different options I've seen:

1. Tap a connection from the OEM sub connector which plugs into the sub. (Post factory Amp)

2. Tap a connection from the feeds to the factory amp from the 16:9 screen (Pre factory amp)

3. Tap a connection from the rear outputs to speaker doors (Post amp)

I've heard it's best to get a "clean" signal that hasn't been through factory amp is this right??

Also do I need to get a cable that converts them from 2 normal wires into a Phono plug for the JL amp input?

Could someone please recommend which method would be best suited for me?

Also could someone explain what this means "Ω" i.e 1Ω@1000w 2Ω@1000w etc..

Thanks!
James
