LJColeman Posted March 19, 2012 Author Report Share Posted March 19, 2012 so have i mate, finally got the Balls to drill holes in my car :L.. No idea what sub and amp setup im going to use yet, but it needs to be a free air sub, i still need to do some reseach into that.. will be using the standard headunit tho, so it keeps it OEM, Amp will me mounted in the spare wheel well out of sight, all cables hidden, just currently researching how to mount the MDF for where the sub will be mounted.. so only a minor build atm, still got some planning etc to do, im a perfectionist so its gotta be perfect :L Link to comment Share on other sites More sharing options...
LJColeman Posted March 19, 2012 Author Report Share Posted March 19, 2012 Id like to know if anyone has tried to install this box to a coupe, just to see how well it fits, as its meant for a vert, but im unsure of what the difference is. Can anyone shed some light? http://item.mobileweb.ebay.co.uk/viewitem?itemId=350544967656&index=16&nav=WATCHING&nid=78332580091 Link to comment Share on other sites More sharing options...

sbonse Posted March 29, 2012 Report Share Posted March 29, 2012 I had a sub mounted in a box through the ski hatch and it sounds really good. Best with the armrest down. I also had the rear shelf sound deadened as well as a had a few rattles and the tennis ball mod didnt work. I posted loads of pics a few years back when it was done. I can dig them out if you want Link to comment Share on other sites More sharing options...
RickyZ Posted March 29, 2012 Report Share Posted March 29, 2012 sbonse I would be interested in seeing the parcel shelf removal as I think mine needs sound deadening as im sure thats whats rattling OP OEM location for subs would be mounted to the parcel shelf on the underside for a coupe, your using the OEM mount for the vert Link to comment Share on other sites More sharing options...
autosri Posted March 29, 2012 Report Share Posted March 29, 2012 (edited) You would be looking at around 200-220 rms for an amp that will run that well Trickster the shelf is easy remove lower seat told upper seat loosen bolsters and remove c pillars and I think the rear speakers have to come out too Edited March 29, 2012 by autosri Link to comment Share on other sites More sharing options...

autosri Posted March 31, 2012 Report Share Posted March 31, 2012 I would keep an eye on the temp of the amp as your not supposed to mount them upside down Other than that it looks good Link to comment Share on other sites More sharing options...

singh41 Posted April 29, 2012 Report Share Posted April 29, 2012 looks like a really neat build. was it difficult to drill and cut out the metal panel?? im thinking of fitting a 10 inch square kicker sub in the hatch. Don't know whether to build a box like you have or mount it free air. Link to comment Share on other sites More sharing options...
Bahnstormer Posted April 29, 2012 Report Share Posted April 29, 2012 This was kind of the inspiration for mine Yours looks much neater though lol, I think I might have to revise my design a little at some point this week. looks like a really neat build. was it difficult to drill and cut out the metal panel?? im thinking of fitting a 10 inch square kicker sub in the hatch. Don't know whether to build a box like you have or mount it free air. I don't reckon you'll fit a 10" sub in the hatch of a coupe, the 8" in mine was a pretty tight squeeze.

singh41 Posted April 29, 2012 Report Share Posted April 29, 2012 righto, will have a look for a square 8" sub as i want to try and make use of all of the space in there. Link to comment Share on other sites More sharing options...

Don't know whether to build a box like you have or mount it free air. I only made a box as I was finding it hard to get a free air sub for the right money, the metal panel is extremely easy to take out, just drill all the spot welds then smash it out Link to comment Share on other sites More sharing options...

Bahnstormer Posted April 30, 2012 Report Share Posted April 30, 2012 Here's the sub I used. It's happy either in an enclosure or as a free air sub. I couldn't get over how shallow it was, it's pretty much flush with the back of the seat! Link to comment Share on other sites More sharing options...
Jay. Posted April 30, 2012 Report Share Posted April 30, 2012 Good progress mate! I did this in my old vert & it sounded the nuts with a kicker 10" sub Link to comment Share on other sites More sharing options...
