Think I may have found the perfect replacement, shall I hit the go button on my cart ??? https://www.parts-express.com/tymphany-tc9fd18-08-3-1-2-full-range-paper-cone-woofer--264-1062#lblProductDetails - Cheap $75 shipped - correct mounting depth - spot on power handling 30rms - low sensitivity (good as I don't want the midrange to high considering the location of them) Although they are .5" higher I should be able to modify the factory fitting to accomodate them, or perhaps even epoxy them to inside of door cards behind the factory grill.

Ive had fujitsubo (FGK) mufflers on an AW11 Supercharged and SW20 Turbo MR2. Marginally louder than stock, like very marginal, yet flowed real well and had a slightly sporty note to them. Good quality mufflers, my SW20 one lasted about 200,000km before it was poked. If you plan to go new then don't overlook the Adrenalin R mufflers down in Hastings. These are NZ made, great value, high quality (rediculously high quality), amazing flow, amazing sound, and most importantly dont exceed to the noise restrictions. Once I get the coin ill be putting a couple of their V8 chamber mufflers in place of the stock cans.

Ahhh yes that would make sense. RE: replacements, I found these substantially cheaper than the Tangband http://www.parts-express.com/aurasound-ns3-193-8a-3-extended-range-driver-8-ohm--296-258 Seem to get alot of good reviews.

Cant really find to much info on the Mcintosh amp, but I believe its 5 channel (4 X 30 RMS + 1 x 78RMS for sub) the sub channel is crossed over, and the all the other channels rely on passive crossover by way of a Capacitor installed into the mids and tweeters. to get a 4 ohm load at the Amp, from 4 x 8 ohm speakers no doubt would require a combination of parallel and serial wiring ?.

The fact that i've eliminated the 3" mid from the setup at the moment, will this have any adverse effect on the impedance the AMP is seeing ? Bit confusing the front setup as it has 6.5" + 3" + tweeter + tweeter...assuming it some combo of series and parallel so it works out to be 4 ohms at amp.

Spent the weekend sorting our all the blown \ perished speakers in my Mcintosh system, dynamatted up and sealed doors, parcel tray and installed a new 8" sub. Turns out the 3" mids were hosed and causing a terrible screeching sound on guitar twangs, I eliminated them but the vocals lack a little now. The factory ones are 20RMS 8 Ohm, I was wondering if I could get away with some 4 ohm Boschmann ones ? or should I just hit Parts Express or Ebay and find some 8 ohm ones.

When I looked at doing my 2004 BP Legacy I seriously considered the Adrenalin R V8 chamber mufflers http://www.adrenalinr.com/productdetail.php?productID=541 $599, a bit cheaper for the Legacy as they shorten them slightly. By the time you add a Y pipe and mid pipe, plus one of their 300mm resonators for $150 you might be up around the $1200 mark. But having constructed a custom V system for an MR2 a few years ago I found their gear to be among the best (if not the best) stuff ever, performance and sound unbelievable. Once the missis goes back to work, i'm shelling out $1200 to get one made up.

OK did some sound testing last night and narrowed it down to the left side 3" midrange just above the woofer. It seems to be producing the highs alot louder than it should. Without being an electronics expert my take is a) the new woofer impedance (although it says 8 ohms) is slightly less and thus the left side draws a little extra power, I recall on install of new woofers the system sounded a little biased to the left. b) the built in crossover on the 3" has failed (perhaps capacitor failed) allowing highs through Does anyway have any other suggestions ? Thinking ill either baffle that 3" with some foam behind the grill, or take the opportunity to upgrade my 3" with something nicer from parts-exchange-com.

Noticed on my drive home last night and this morning that the new woofers make a harsh screeching sound on the highs (inc some vocals). Quite hard on the ears, pretty sure the baskets were mounted flush when I installed, and certainly didnt notice any harsh sound on my initial testing tracks. Definately different to what I heard straight after install as I dont really want to listen to them now. What would cause such an issue ?

For $166NZ shipped off amazon I can get a Pioneer TS-W2002D2 8" Shallow mount, apparently its free air, also has the advantage of not interfering with the boot mechanism.

Home audio for all the front stuff as its 8ohm. But yeah ive been looking at all the 8" options in car audio and very little I can find that are a) high sensitivty (>89db) b) closer to 100rms power c) mounting depth <4 inches ill look into that DD 6.5, is Scoob selling his or do I need to pay retail

On the subject of QMS Im looking into doing the factory sub, and am dicing up between a) a GRS-8 8" Subwoofer (100rms, 4ohm, infinite baffle) b) a 6.5" subwoofer of some sort Im leaning toward 6.5" mounted in an 8"-6.5" adaptor\spacer (for easier install). Then layering up the parcel shelf with some dynamat (or not). Is there any suitable 6.5" suitable for infinate baffle ? perhaps another one of those Jaycar 6.5" ?

Nah the basket didnt quite squeeze flush with the factory spacer ring. I understand the Vifa woofers are drop in, but for $41 each and the sound output I was happy. Debating now whether or not to get some foam baffles to go behind the woofers to protect them from the elements since I ditched the factory spacer with weather sheild. Do they need them ?

OK this is now officially a review thread, replaced the fronts with these on weekend http://www.jaycar.co.nz/Sight-%26-Sound---Home/Hi-Fi-Speakers-%26-Accessories/Component-Speakers/6-5-Paper-Cone-Woofer-Midrange/p/CW2194 Had to ditch the factory brackets and secure them direct to the door (magnet size was too big to fit through the spacer hole). Must say for a $41 speaker (each), they produce a very nice punchy mid bass and almost as much bass as the factory 8" sub. Ive use Response brand before in the past, and as per the older models, they don't dissapoint. They dont upset the balance of the system, and id rate them a 10-15% improvement over stock. Settings after install Bass +2 Treble -2 Fade - Front +9

OK after a bit more reading and self debate, I ended up getting the Vifa 6.5" Woofers (2 for $50) since another member had already used them (rather rely on ears than specs on paper). Also managed to fix the stock sub vibration last night, seems the foam edge rubs against the outer plastic ring of the woofer and causes the noise, most likely due to deformation with age, so applying some pressure at that point using some closed cell foam wedged between woofer and parcel tray seems to make it compliant and doesnt affect the bass output. Hopefully enough to get a couple more years of good music before selling.

Yeah seems that most of the leggys for sale (especially at dealers have crazy high kms) We were ultra fortunate to pick up our 2004, 4 years ago with 63,000 kms for $16,000. Today you have 2006/2007 models with 140,000+ and the dealers want $14-$16k for them still.

Been doing a bot of crash course in small theile parameters today and comparing Vifa, Jaycar Response and Cheap Surplustronics Kevlar speakers (their 6.5" models). Interestingly enough (on paper anyway) the Surplustronic Kevlar 6.5" ($35) seems to win on a range of values that make it an ideal mid bass speaker for small enclosure (ie car door). While the Vifa pretty much loses out on everything by Frequency response. Key specs of the Surplustronics - Good Re 7ohms (closer to rated 8 Ohm the better) Vifa was 5.7 - Good frequency response 50hz, Vifa slightly better at 46.9hz - Excellent QMS of 7.1 means small enclosure suitability, Vifa was 2.6 - Vas of 10 vs 31, means better control of woofer cone - Higher sensitivity 88db vs 87 for the Vifa - Lower RMS (125rms) vs (160rms for Vifa), hopefully means small McIntosh amp can drive it. The jaycar Response was sort of inbetween but had terrible QMS of 2.02, meaning it was suited to a large enclosure

Yeah its all the stock stuff including the headunit, im running an AnyCar MP3 unit in glovebox to provide MP3 capability. Im hoping I can get a replacement 6.5" speaker close enough to the Mcintosh specs and design, so far one forum member reckons the Vifa woofers sound better than stock, i'm also eying up the response 6.5" woofers from Jaycar at $41 each that are similar design (8ohm, good sensitivity, paper cone, lowish RMS rating 60RMS) Really looking for a sub $100 fix as the car will be sold in 2-3 years time, and its going to cost $1200-$1500 to do a half decent amp+components+sub+headunit. Time is also a luxury for me with a newborn (as well as money).

I could possibly use another 2 in my Colt. Whats the deal with running a pair of 8 ohms in my rear doors and powering off the headunit ? (Pioneer 4X50) I currently dont use any of my HU channels as I run Amps for my fronts and sub. The rear doors are treated with Dynamat and about optimal size for 6.5" mid bass driver so might provide a little extra bass in the rear.

Pretty high KMs for $15,000 My pick would be http://www.trademe.co.nz/Browse/Listing.aspx?id=924104134 - rare colour - manual - leather - slightly lower kms - mcintosh stereo Offer them $12,500 and spend the $2500 change on ecu tune, subtech pipe, air filter.

Yep only been looking at 8 Ohms ones. At the moment its between the Jaycar Response (which ive had good experience with their car stuff). and some Vifa ones I found on TradeMe, but the seller wants $140 for 6, I only need 2 . If anyone else here is keen to replace theirs Ill buy all 6 and sell the remaining ones at $50 a pair.

Would these be good ???? http://www.jaycar.co.nz/Sight-%26-Sound---Home/Hi-Fi-Speakers-%26-Accessories/Component-Speakers/6-5-Paper-Cone-Woofer-Midrange/p/CW2194

Got one here, running PBMS Tune and Subtech Front Pipe + Simota Panel Filter (2004 GT Spec B - Tiptronic) The Subtech front is raspy and sound horrible. Replacing the centre pipe with a 300mm long Adrenalin R Resonator ($130) made a world of difference (nearly stock sound). As for the tune at PBMS in Pukekohe (Gary Capper) OMG, the car has bucket loads of power to dip into all the way upto (and beyond) overtaking speeds...181kw at all 4. Fuel economy was improved with best achieved so far of 7.9L per 100 km (confirmed with actual fill, not computer, but the computer is quite accurate too). For under $2000 on top of purchase price it makes the BP5 a bargain car when you compare it to other similary powered (and nice looking) speced sedans out there.

Sounds like my front left woofer has started to perish. I read in a below thread you can use Vifa\Tymphany 6.5" 8 ohm woofers. But cant find anything in NZ or reasonably priced. Wondering if the following would be a candidate ? http://www.surplustronics.co.nz/products/576-wide-range-kevlar-cone-woofers-65-inch- Alternatively i though perhaps rebuilding them with new foam\rubber http://www.simplyspeakers.com/speaker-rubber-edge-repair-kit-rsk-6.5.html

Having owned a 2004 GT for 4 years and 30,000kms id say they are equally reliable, we only service ours every 10,000 kms and its been ECU tuned and Subtech piped from day one we brought it. (181kw at wheels, which equates to well over 215KW at engine). Beyond 150,000 id be wanting the 3.0R though (lack of turbo) Some of the 3.0R guys overseas are getting > stock GT performance through ECU mapping, front pipes,exhaust and cold air intake. Our second car will be such a 3.0R....if i can find a buyer for my Ralliart Colt
