Hi all,

So I have been thinking about getting a small slim line sub and amp similar to the under seat subs, but was wondering if a sub can be directly wired from the rear speakers rather than connect it directly to the rear of the OE head unit which requires a massive amount of effort. I am just looking for a little bit of base, nothing massive.

Apologises if this is a really dim question, but I have heard of people doing this before just not on a type r.

Any advice appreciated.

the short answer is yes you can

if the amplifier / sub combination you use has a high level input it would be a simple case of wiring the high level input to one or both ( if you use both channels L + R input ) of the rear speakers

if your amplifier / sub combination has only line level inputs ( phono ) you will need to use a LOC to reduce the speaker output to line level

there's not much more to it and pretty easy to do

Yes I've done it, it transforms the sound from the OEM headunit.

Really I would consider an active sub to be a first step of an upgrade although other people say change the head unit first.

I installed the Alpine SWE-815 and it sounds sweet, the amount of bass that small box produces is pretty impressive.

Alpine - Powered Subwoofer Boxes - SWE-815

bought mine from here when it was £89.99 Alpine SWE-815 Road Radio

I also bought the wiring kit although this comes with everything you need to install it. One thing to note is you are still going to have to run a +12v power from the battery to the boot so you will need to pull up/take off some trim but it's really not that difficult if you take your time.

I think I am going to go down this route. So I don't need any of the add ons??

Also got the swe-815. Nothing else is required, all is in the box.

You need to run the 12v from the battery (supplied cable) and then hardwire the sub directly into the speakers as it takes a high level input.

Amazing bass for such a small unit. Defo recommended.

I bought mind around a month ago from roadradio as they were the cheapest at £96

Got my SWE-815 delivered today, might attempt installation at the weekend. The instructions aren't what I'd call thorough but the wiring all seems to be there which is a bonus.

Is the general consensus to use the cigarette lighter/12v outlet for the remote trigger?

Remote

Does anyone have any advice on how to get the remote cable sorted, where should i get the remote signal from to turn on the sub ?

Yes, I use the cigarette lighter socket in the rear for the remote. Unless you are planning a super clean install just buy a cigarette plug from eBay and wire your remote into that.

hello what would be the super clean install instead of using the lighter socket?

There’s no need to be super clean as it’s all hidden away. I connected my under seat sub remote line to the front cig lighter, and powered the sub via the fuse box. It’s pretty simple to connect it all up & adds a bit of power that the poor stock Honda ones are missing out on.

Have you had any issues powering the Alpine sub from the fuse box rather than running power back to the battery? Everyone online goes nuts about NEVER doing that, but never actually really explains why. This is a 150 watt sub with a 10 amp fuse. Seriously? I keep thinking going to the fusebox with this should be fine given the minimal draw-- especially as the firewall grommet is a bitch on my car.

my sub is wired through the fuse panel there was a spare fuse holder ( fuse 31 ) for something my car is not equipped with so i used that
fuse 31 is marked as not used but there is still ignition live going to it

get one of these to connect your power wire from the sub

i'm reasonably sure it's the micro blade fuses the civics use if not it's the mini blade which is one of these

mines been wired up this way for the last 5 years or so with no detrimental effects what so ever

Nice one, cosmicma. Thanks-- I've got the piggybacks and am going to install next week. Appreciate the help. I can understand the need to go the battery with a high-powered amp or sub, but this thing is only running 150 watts.

Where exactly is the grommet located in the firewall?
I have a high-powered setup I'd like to install but I have no clue as to the easiest way through the firewall.
