Spoony Member 250 Member For: 14y 1m 16d Gender: Male Location: Brisbane Posted 15/11/10 09:18 PM Share Posted 15/11/10 09:18 PM dynamat is my next thing. I did notice just how flexible the shelf is though (grab the back of the sub and can move it/shelf a fair bit, the fact the driver is quite heavy to prob dont' help). This would likely be more of an issue once better amped(powered) but wouldn't be helping eitherway. Dynamat probably wont help here much but short of bracing the shelf probably not much can do. No I need to work out what front speakers. I've read only good things about these Shopping Secure - Car Audio Specialists - SPL Dynamics SD-6.2 expecially for the price. Might put the std front speaker split setup in the rear. While obviously still crap, seem much better than what is in the rear standard? Link to comment Share on other sites More sharing options...

Spoony Member 250 Member For: 14y 1m 16d Gender: Male Location: Brisbane Posted 01/12/10 12:12 AM Share Posted 01/12/10 12:12 AM I 'bogan spec' sound deadend the parcel shelf last night (using FlashTac, already has some so why spend $'s on Dynamat). I've still gotta redo my 8 to 10'inch MDF spacer as its no 100% atm, but as other have said, Dynamatting the parcel shelf does help and is noticable.

1600dave Donating Members 872 Member For: 13y 10m 18d Posted 02/10/11 12:21 AM Share Posted 02/10/11 12:21 AM Well I must say I am very happy with my Polk. I just need to dynamat the parcel shelf now.Tim,With the MM840DVC, how do you have the voice coils wired, series or parallel?I didnt think the stock amp would handle a 2ohm load too well, but if yours is still going, might have to give it a go.Might be why the Polk performs too, as the amp would be putting out more power that way.If in series (giving 8ohms) I'd imagine it'd sound worse due to the low power it'd be getting.They do make a single voice coil 4ohm model too.

Bolted straight in without any mods. I also dynamatted the rear shelf.Very happy with the results. Massive improvement over stock.While I was at it I also replaced the front speakers with some Alpine Type-S 5x7s. Again, a big improvement.All up, for about $300 (including a sheet of dynamat) the stock premium audio has been transformed into something listenable.

The Alpines were a straight swap for the stockies. Link to comment Share on other sites More sharing options...
1600dave Donating Members 872 Member For: 13y 10m 18d Posted 19/10/11 06:28 AM Share Posted 19/10/11 06:28 AM Strange. Mine didnt have a sub (but had the amp) although it was ex pig spec.The stock tweeters are pretty sh*t anyway.So you have tweeters now? Used the Alpine crossovers and ran your own wiring?
