Adding a sub
Evening all. I have an E91 with HiFi (676) system that I've upgraded with a JL XD600/6v2 running fronts, rears & underseats (using a Technic harness).
I'm thinking of adding a sub in the boot - is it possible to run the sub off the same amp? |

Your best bet is to drop TechnicPNP an email.
But I don't see why you couldn't tap woofer signals on the harness and then into a LOC. You'll probably need a second amp?

Thanks for replying.
Had chance to have a bit more of a look in to it & contacted TechnicPNP as well. He said to just take a feed from either the front or rear signals coming from the headunit (same signal). I will need another amp although originally I was hoping to somehow just use the existing XD600/6v2 - only way to do this I think would be to disconnect the underseats so I've got hold of a XD300/1v2 to power the sub. The only problem I now have is where to put the sub! I wanted to put it under the floor but then realised last night that I have the shallow underfloor trim (I assume) because of the twin exhausts on the 335. Looking at side mount behind the right wheel arch or possibly a very shallow mount sub (eg JL 13TW5v2-4). |

You want a custom side enclosure... visual ice on FB
Search my recent posts and you'll find some pics, think I put them in the 'what has your 335i cost you this month' thread

I'm glad you mentioned Visual Ice - found him on FB & saw he'd already done some E90/1 stuff. He's going to take a look at the side mount but also under the floor with a slim mount sub, although I don't think the volume is there even if the sub will physically fit.
I'll have a look at your pics, cheers... |

I have been speaking with Visual Ice too, regarding a Sub enclosure, hopefully ordering next week.
I ordered one of the generic ones from Ebay and it didn't fit properly and was the wrong colour, it got sent back quite quickly! My setup is base audio, so I have a little coding to do first. Planning on a full audio haul myself Last edited by scottym; 01-25-2018 at 10:17 AM.. Reason: Image adding |

That eBay one looks terrible!
I don't envy you having to deal with base audio, so glad mine came with HiFi! I've done all mine myself so far. I can highly recommend the MB Quart 200.3 direct fit kit coupled with a JL XD600/6v2; sounds leagues ahead of what was in mine as standard. Quote:

Guys
I may have a visual ice enclosure for sale soon. It has a 12" JL Audio 300W speaker already installed with a proper JL grille. I also have a perfectly matching 300W RMS Kenwood amp. Thing is, I've not actually determined if I'm selling it yet or not, but I thought I'd give you a heads up. If I sell my E90 soon it's all up for grabs. But I thought I'd mention it before you invest in all-new kit. Depends how much of a hurry you are in to get your subs installed!! As well as that, I have the Technic PNP harness and LOC for the HK system (which probably isn't of any interest to you if you haven't got HK speakers).

I recently got an e90 325i with logic7 and am thinking of adding a sub. I already have a jl audio mono amp and 12" in a sealed enclosure but probably want one of the visual ice corner enclosures and will need the technic harness with loc. Did you sell yours @texasjohn or still thinking about selling the car?
