Decided to create a consolidated thread for everyone to voice their opinions and ideas here. From now on any one posting about opinions on the following items will have their threads merged into this one:

- what headunit to buy

- what speakers to get

- alarms

etc

Any other questions (eg problems, technical advice) will remain as they are.

Cheers,

Ermm... what kind of solvent? If you know of one that will take the goo off but not eat my paint or damage the rubber door-seal, i'm all ears!

Cheers!

hi guys,

i have a jvc headunit atm

running 2 150watt 6.5" mtx tdx6502 2 way speakers

with NO speakers in the front atm

got a 2 ch cadence amp in the boot

which combination would you guys reccommend?:

1.put new 6x9s in the rear and chuck the 6.5"s in the front,

which is going to need alot of customising with mdf ( after reading a few threads in the forum)

and get a new subs later

2.just leave the 6.5"s in the rear and buy new subs?

buy front splits later

i normally jam up rnb and techno (which needs ALOT of bass)

any help will be appreciated

thanks in advance guys

I have to get a few things on my car fixed and am going to upgrade the stereo at the same time so I was after some advise...

the car is a r32 GTR and what I've been quoted on is this:

Clarion mp3/usb headunit $310

Clarion 5" splits for the front $110

Clarion 6.5" 3 way rears $100

Clarion 12" Sub $190

Clarion monoblock amp $220

Fitting + cables etc $250

now origonally I was going to have 2 or 3way in the front and 6.5" splits in the rear with a 4 chan amp with 2 chanels bridged to drive the sub...

the salesman talked me out of this and sugested the option I listed.

so whats the go? or do you have a better suggestion for me?

brilliant idea.

lock my thread and ask me to ask my Q here for sweet fruck all response

Ah yeah, I run a newer amp now... the JayCar 100wrms unit, which seems to drive them just as well as my old (large) amp. I have the balance faded to the front (+7), and the JBL's still flop around like crazy. I'm running the higher end crossover, so they are hardly getting any lower frequencies. This has stopped them from throwing the coils, but now have ZERO bass.

I might get another pair of Clarion splits, as I had suggested... $200 new, I can find them for $100ish nowdays... the new models have brought the older ones down.

Hey, if you really want to install a proper system you MUST have the same brand and series of speakers in the front and rear. They don't necessarily have to be the splits but they must be a Clarion speaker from the same series. As you don't need split's in the rear, a clarion 2 way coaxial 6.5" speaker (from the same series) would probably be a good choice.

The reason they must be the same front and rear is they must be made of the same material (to really sound good), and have the same crossovers or you can end up with phase issues.

The sub can be a different make of speaker but the front and rears must be the same. If you want any real bass or volume you definately need a seperate power amp. Contrary to popular belief your amp should always be rated higher than you speakers.

Yeah I see what the sales man is saying, you want your splits in the front with the treaters mounted on the dash board (facing you), as this is where all your high end comes from. Split's in the rear are a complete waste of time, the rear is really only used for fill. You want most of your sound (especially the high end) comming from the front.

I'd go the 5" split's (or 6" if they fit) in the front, and either 2 or 3 way 6.5" coaxials in the rear.

The clarion mono block amp sounds fine, but I would also definately get an amp for the front and rears as well.

if you want equipment stuff i would suggest

decks -

alpine

kenwood

jvc

coax's/splits

mtx

kicker

earthquake

bostons

alpine

subs

audiobahn

mtx

alpine

earthquake

kicker

amps

earthquake

alpine

kenwood

soundstorm

jbl

stuff i have had problems with

- rockford fosgate power series 6.5 " coax, there top of the range coax's 2 sets

- pioneer deck + pioneer speakers + pioneer mono block

- sony.. only thing that compares to pioneer for cheaply made china crap at overly expensive prices.. but her it looks pretty

- fusion subs 1 tore a surround and another just stopped working

- pyle mono block (was great while it worked but shorted out very easy)

- cadence rca cables, they are crap, look awsome but really poor workmanship, friend also had problems with his cadence amp cutting out

- boss audio subs, haha what a laugh u buy them to blow them up just for something to do

any way i hope i helped some people with there descisions

also what to look out when purchasing equipment

power ratings can be very descieving as companies like pioneer sony etc throw on brandings like 400 watts or 350 watts which is peak power, all these ratings are false, as they cant run on peak power for more then about a second or 2 before they will blow, same as amps subs etc

generaly with the most common brand name stuff like sony kenwood pioneer etc they speakers are usually about a quarter or less of what the peak is, so how can you make sure how powerful they really are? check for nominal power rating or continious power rating aka rms this is the best indicator of how much power they can handle, generally for an average system about 50watt rms will be more then enough for your 6"s and about 60+ should be nice for 6x9's, subs you want to have at least 300 watt rms or more to have enough kick

with amps you need to be very careful as underpowering your speakers will cause sound clipping and damage you speakers, how do you know if you have sound clipping? you will hear when you crank up the volume, distortion and loss of certain sounds or a jerky inconsistant sound.

how to make sure your amp can run your speakers? as mentioned before look at rms ratings not peak power, so if you have 2 sets of 60 watt rms speakers you will need a 4 channel amp which around 70 watt rms x 4 and just leave the gain down a little, with subs same again if you have a sub which is 400 watt rms you will need an amp which is say 350-500 watt rms to power it properly, you also need to keep an eye out for a thing called Ohms too, i beleive it is a rating of ristance/current, so how does this work? well most rms ratings are at 4Ohms for car speakers some times may be rated at 2 or 1 or even 8, basically easiest way to work this out is say something @ 4 Ohms is 500 watt rms, 2 Ohms will be double the value so will go upto 1000 watt rms @ 2Ohm, and 2000 watt at 1Ohm and if it went upto 8Ohms would be 250 watt rms

BE CAREFUL!! not everything can run @ any ohms some amps may only be able to do 4Ohm and some may be able to do anything you want safely so make sure the ohms rating and power ratings all match up before you purchase your product as poor product selection will resualt in bad sound and possibly speaker damage

as for wiring, always make sure you rca's and speaker wires are not near your power cable, your ground wires always need to be either same size or larger then your power wire

for general systems your single 8awg wire will be enough to run 1 or 2 amps under about 300 watt rms each, as you start getting bigger you need to look at 4awg to 0awg which is the fattest, and remember make sure you ground is bigger then the power!! example if you have 8guage wire from engine to amp you will need at least 8 guage as a ground to the amp, or even better 4 guage!

if any one has any questions or did not quite understand please feel free to ask, and if any one disagree's on what i have said, i am not a professional, just what i have learnt in the last few years wasting on money on audio equip and installing

thanks for reading hope i helped :)

Yeah I agree with what your saying, esecially with regards to power ratings.

As you said only ever look at RMS ratings (peak is a crock), and make sure your amps are rated at least a little higher than your speakers.

Only thing I would disagree with is some of your brand preferences (although I guess it partly comes down to personal preference):

Highy end decks

I don't like kenwood

JVC and Clarion are good

My preference would be alpine

coax's/splits

mtx (don't know)

kicker (Good)

earthquake (Good)

bostons (Excellent)

alpine (Good)

My preference for speakers would DEFINATELY be Focal

subs

audiobahn (Don't know)

mtx (Don't know)

alpine (Good)

earthquake (Good)

kicker (Good)

My preference for subs would DEFINATELY be Focal

amps

earthquake (Good)

alpine (Good to high end)

kenwood (Don't like)

soundstorm (Don't know)

jbl (Good)

JL also make some of the best amps around and would be well worth considering

    • Hi, i’m making a rb25det coil loom for Vag short coil. Can anybody tell me which Ecu signal wire belong to coil number 1 and 2,3,4,5,6? The connecting switch in above pic is 8 wire i think white is for +12v and black for earth.
    • Was there ever a model of the Stagea m35 that didnt have a badge on the grill? I thought I saw that somewhere, some aero edition or something? I cant find it again? davemoto
    • Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.
    • I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.
    • Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
