Adding A Powered Subwoofer In The Trunk

[Antti Salonen]

Another question while I'm at it... I'm in the process of upgrading the standard speakers my Coupé, and I already replaced the front door speakers and the tweeters on the dash board with a new set, and added some sound proofing on the inside of the door panels. With the (absolutely awful) rear speakers unplugged the sound is now reasonably good even with the standard RD4 head unit, but the low end is obviously lacking. I guess I'll eventually end up replacing the head unit as well, but that'll wait for a while.

 

I picked up an Infinity BassLink active subwoofer at a very reasonable price, and once I get it it'll be installed on the side of the trunk. It has speaker level inputs so connecting it to the rear speaker wires won't be a problem. I'm not sure if there's 12V available somewhere from the trunk, but in any case I think it'll be necessary to run a good thick cable straight from the battery with a fuse near the battery.

 

So can any of you give any pointers regarding how to route the power cable? From the passenger footwell I can run it under the floor mat and then under the seat but what's a good (and possibly easy) way to get it from the engine compartment to the passenger footwell?

Have a read through might find somewhere like that to route the cable through. If not drills at the ready.

I finally installed the Infinity BassLink today. It was reasonably straight forward, and I ended up doing it a lot like it was done in wozza's example. I took the power from the fuse box next to the battery, attached the fuse holder on the battery and took the cable to the passenger footwell (the right side of the car). From there I just run the cable under the removable floor mats (option) and the seats, nicely out of sight, all the way to the trunk.

 

The BassLink takes speaker level signal, so I removed the rear speakers (this is a coupé) and extended their wires a bit and connected them to the subwoofer. The front speakers were replaced earlier with Pioneer TS-Q171C. I'm sure there are a lot better component speakers available, as these don't have separate crossovers (just a highpass filter in the tweeters), but then these were only 130 euro.

 

The sound is quite nice with the stock Blaupunkt RD4. The BassLink is definitely the strongest link here and it doesn't take a lot of space in the trunk. I also added some dampening in the front doors and around the trunk, ant the whole upgrade cost just 500 euros. It's pretty easy to do and I believe a good way to upgrade the stock audio system. With a bigger budget the Blaupunkt RD4 would definitely be the next one to go, although I would definitely like to keep the steering wheel controls.
