toyokid 27 Report post Posted June 12, 2014 I have an Alpine 925 dab head unit fitted (thanks Lauren) and a Pioneer spare wheel well sub. It has improved the sound, but also left it slightly unbalanced, needing more va va vum up front! Having done a little research on this site, I am considering amping the door speakers and tweeters. Components for consideration are 6.5" Focal door speakers and tweeters mounted using spacer plates The speaker packages seemed to be lumped with "crossover" boxes, which I do not understand! Should I use crossovers, they need to be mounted somewhere, the neatest I have seen being the boot Then there is the amp, having a self driven Pioneer sub in the boot, I only need to drive 150 odd watt door speakers and tweeters Does this mean that I need 4 Chanel? Can it be small and mounted under the passenger seat? Would an Alpine amp make installation easier, when tying in with the head unit? Btw I do not want to lose any boot space Thanks in advance Stephen Share this post Link to post Share on other sites
rob275 1817 Report post Posted June 12, 2014 All Component systems tend to come with crossover boxes, it filters the High's & Low's to the Tweeter and Mid-Bass If you're just amping the fronts, you need a 2 channel, One channel goes in to each Crossover and then Splits to the Tweeter & Mid-Bass Brand of amp won't make a difference to the simplicity of the install, I also wouldn't mount it under the seat, not much room, and could be a potential fire hazard with heated seats. In my previous cars i've put the crossovers behind the door cards, though you can put them in the boot and a lot of people do, it's just a little more wire.

toyokid 27 Report post Posted June 12, 2014 Just bought an Alpine amp, seemed cheap enough, dealer was selling it off as "demo unit" PDX-F6 4 channel, will probably look to mount it together with the crossovers in the boot. I have a roll of 2mm insertion rubber lying around, maybe pull all the foam out of the boot/spare wheel well, then cover it? Just need to decide on which Focal 6.5" speakers to fit? Any ideas? Looking to buy today. Dynamat or similar to cover the doors? Any cheaper alternatives? Anyone wish to fit my box of tricks? Stephen Share this post Link to post Share on other sites
rob275 1817 Report post Posted June 12, 2014 Not too clued up on the deadening but you can't really go wrong with Dynamat, Again i've not used any Focal Comps before, how much are you looking to spend? Share this post Link to post Share on other sites
toyokid 27 Report post Posted June 13, 2014 ordered these http://www.ebay.co.uk/itm/250978150930?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649 how much quantity of dynamite do i need? Share this post Link to post Share on other sites
rob275 1817 Report post Posted June 13, 2014 it depends how much you want to dynamat really... I'd say get the bulk pack they do if you want to do the whole boot etc. Share this post Link to post Share on other sites
Jamie_GRMN 177 Report post Posted June 13, 2014 With dynamat you don't need to cover the whole panel, there is a guide somewhere on the internet... Work out the area of the panel and it'll tell you what surface area of dynamat you need then stick that in the centre of the panel, anymore is overkill really. Not sure how well this method will work on the boot floor due its complex shape, but doors and body panels it is definitely the best way to go. Share this post Link to post Share on other sites
toyokid 27 Report post Posted June 13, 2014 Just the doors Jamie, any idea of area? Thanks Share this post Link to post Share on other sites
Jamie_GRMN 177 Report post Posted June 13, 2014 Haven't had the door cards off to have a look at the shape of the inner skin, but the outer I'd go for a 15cm*15cm square in the centre, should kill any vibration in that you may get. For the inner skin add a ring between the speaker plate and door and any largish area add a square as close to centre as possible. Share this post Link to post Share on other sites
Lauren 2259 Report post Posted June 13, 2014 I've got those speakers in my car. I have a number of other additions and don't use any of the OEM equipment. They are excellent to be fair. Share this post Link to post Share on other sites
forge197 12 Report post Posted June 13, 2014 I've those speakers too and my thoughts are the same as Lauren's their excellent Share this post Link to post Share on other sites
toyokid 27 Report post Posted June 14, 2014 Just ordered the speaker template/baffle from Patrick Henry today, which will place the tweeters in the oem position I think that I will need to clear the boot of all foam etc to mount the amp and crossovers? Then after sound insulating everywhere glue some of the foam back in to support the boot carpet? Stephen 1 Mark@Abbey M/S reacted to this Share this post Link to post Share on other sites
Lauren 2259 Report post Posted June 14, 2014 Better to put the tweakers at the top of the doors in front of the interior door handle for sound quality. The OEM position isn't ideal. Share this post Link to post Share on other sites
toyokid 27 Report post Posted June 15, 2014 Should get some banging beats? The motivation for upgrading the existing kit, being it didn't seem too well balanced, the subwoofer was kicking out good bass but the front end was flat and not engaging Share this post Link to post Share on other sites
forge197 12 Report post Posted June 15, 2014 toyokid - do you have the JBL upgrade currently? I sound deadened the door behind the speaker and then blocking up all the holes where possible, of course there are cables and stuff you have to let through but you can get to 95% sealed I think this made a big diffrence the midrange upfront Share this post Link to post Share on other sites

toyokid 27 Report post Posted June 17, 2014 One consideration being the heat generated from the amp, was considering mounting all below the carpet, but now thinking bout a custom enclosure in the boot, maybe using mdf? And having the amp level with the boot floor, giving more heat dissipation? Any thoughts? Stephen Share this post Link to post Share on other sites
Lauren 2259 Report post Posted June 18, 2014 Mine is flush mounted with the carpet. It does get pretty hot. When it's been covered by luggage it has overheated twice on long road trips, over the Alps and through Germany in high temperatures. Half an hour later it works again.
