hey all!

just a quick question !

i got this 12"sub http://mobile.jlaudio.com/products_subs.php?series_id=16 (on the left colum) and i am just wondering if this amp would be powerful enough http://www.lifestylestore.com.au/products/car/Sony/2-Channel-Amplifiers/XMZR602/ or should i get some more powerful ? im just looking to wire up my sub and my front speaker.

if anyone have any advice of amps please help me out. or if you have one for sale would b goood too.

(looking at around $100 to $200)

thank you!

i am no expert so someone can confirm my limited knowledge but i thought u would need a 4 channel amp to run the subs and the front speakers, unless the front speakers are run off the head deck, then this might be ok to power the sub. someone who knows there stuff should be able to confirm

more power then that, you would be disapointed and sony isn't my first choice in amps or even in top 20 choices

the sub needs about 300watts RMS but more is better then less. to a point that is,and get a proper box for it. not generic if possible.

a 2 channel amp like this can run the whole car with the right passive crossovers installed. and proper ohm loads but the power is meager at best.

hate to say it but import a amp from usa is a huge cost saver right now. even with shipping. just select a good one cause the warranty will most likely be void here.

I'd look for something name brand , 4 channel, 150 a channel at 4 ohms , you can do a ton of ways to set it up depending on what your goals are and how loud you want it. ?

sony is crap. IMO get a 4 channel; 2 for your fronts (hopefully splits) and bridge the other 2 channels for the sub. Option audio make a good budget amp (that I have used) if you are going to buy locally.

option audio is good, they're made by a chinese firm, and rebranded you would be shocked to see how many brands are the same amps.

when you run amps mixed mode, the passive crossover uses up some of the power. not much but some.and the cost of a coil or two for a sub exceeds the savings on the amps

splits in the doors, tweeeter near the mid for staging

amps I'd sugguest depending on budget and where you buy, (50-150watts per channel max)4 channel amp with active crossover (most have that built in ) run the fronts off the amp, bridge the rear channels to feed to the sub

somewhere in the 200-300 watts of clean max power should push it good even up to 500 watts max/peak but then you might void your warranty on the sub. the box needs to be right. the voltage needs to stay above 12v

the signal can't be distorted a lot and it won't play all day long at max volume, or kiss it good bye from a burnt voice coil

in no certain order

Rockford Fosgate

Orion

Kicker

Option Audio

lanzar opti or pro

MTX

earthquake

JL - same guts as MB quart on lower models.

Percision Power- no sedona series

Soundstream

Directed

Hifonics

Alpine

US Audio old stuff, blue , purple, red models. often on ebay cheap. these have guts from a major SPL brand in them

Jaycar , often overlooked but same guts/heatsink as option audio on older models, 1st place winner in major car mag. saw one on clearance just the other day for your price range.

Pionneer- upper models

Kenwood -upper models

Clarion - give chris rogers a call for those

Boss audio , mid models and up are cheap and ok for some basic installs

heaps more

but I'd be wrong pointing you to websites that sell these cheap, transshippers can create problems for local biz in USA and OZ and voids warranties etc.

call around, and find a decent installer.

don't forget your wiring will cost around 40 bucks in kit form min.

+1 for jaycar, had an old response amp in my VL and it pumped. And it was only a couple hundred brand new from memory.

Personally I would buy locally if dabbling in this entry level gear, for the peace of mind of warranty. Assuming the warranties are worth the paper they are printed on!

troy,

I also do RF. have plenty of that in my own drive car.

a 4ch amplifier would do nicely for the task at ahand. a RF 400.4 will do VERY well.

if thats a bit expensive for your taste grab a clarion one. quite a bit cheaper and still has decent power.

not a fan of option - found that in comparison against the other two they seem to have less output.

Now usually I'd pay out on sony too but the other day I was given the opportunity to try their xm1s monoblock. It's a tiny 500w rms class d. I connected it to my type r and was reaaly impressed with the sound. I was runnung my sub at 2ohms and it pumped hard. But the best thing is that it practicaly didn't heat up at all. I ended up getting it in the end. Sorry if that was a bit off topic...

hi bro one amp that people do not think about is the audio line amps now i know that they are shit as for 2 and 4 channel amps but with the mono amps that you have they are great you can get a 800.1 for $189 from jb and they are quite good for the money. i work for them and we have tested it against all kinds of amps and its mad for the money.

    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
    • Hi,  Just joined the forum so I could share my "fix" of this problem. Might be of use to someone. Had the same hunting at idle issue on my V36 with VQ35HR engine after swapping the engine because the original one got overheated.  While changing the engine I made the mistake of cleaning the throttle bodies and tried all the tricks i could find to do a throttle relearn with no luck. Gave in and took it to a shop and they couldn't sort it. Then took it to my local Nissan dealership and they couldn't get it to idle properly. They said I'd need to replace the throttle bodies and the ecu probably costing more than the car is worth. So I had the idea of replacing the carbon I cleaned out with a thin layer of super glue and it's back to normal idle now. Bit rough but saved the car from the wreckers 🤣
    • After my last update, I went ahead with cleaning and restoring the entire fuel system. This included removing the tank and cleaning it with the Beyond Balistics solution, power washing it multiple times, drying it thoroughly, rinsing with IPA, drying again with heat gun and compressed air. Also, cleaning out the lines, fuel rail, and replacing the fuel pump with an OEM-style one. During the cleaning process, I replaced several hoses - including the breather hose on the fuel tank, which turned out to be the cause of the earlier fuel leak. This is what the old fuel filter looked like: Fuel tank before cleaning: Dirty Fuel Tank.mp4   Fuel tank after cleaning (some staining remains): Clean Fuel Tank.mp4 Both the OEM 270cc and new DeatschWerks 550cc injectors were cleaned professionally by a shop. Before reassembling everything, I tested the fuel flow by running the pump output into a container at the fuel filter location - flow looked good. I then fitted the new fuel filter and reassembled the rest of the system. Fuel Flow Test.mp4 Test 1 - 550cc injectors Ran the new fuel pump with its supplied diagonal strainer (different from OEM’s flat strainer) and my 550cc injectors using the same resized-injector map I had successfully used before. At first, it idled roughly and stalled when I applied throttle. Checked the spark plugs and found that they were fouled with carbon (likely from the earlier overly rich running when the injectors were clogged). After cleaning the plugs, the car started fine. However, it would only idle for 30–60 seconds before stalling, and while driving it would feel like a “fuel cut” after a few seconds - though it wouldn’t fully stall. Test 2 – Strainer swap Suspecting the diagonal strainer might not be reaching the tank bottom, I swapped it for the original flat strainer and filled the tank with ~45L of fuel. The issue persisted exactly the same. Test 3 – OEM injectors To eliminate tuning variables, I reinstalled the OEM 270cc injectors and reverted to the original map. Cleaned the spark plugs again just in-case. The stalling and “fuel cut” still remained.   At this stage, I suspect an intermittent power or connection fault at the fuel pump hanger, caused during the cleaning process. This has led me to look into getting Frenchy’s fuel hanger and replacing the unit entirely. TL;DR: Cleaned and restored the fuel system (tank, lines, rail, pump). Tested 550cc injectors with the same resized-injector map as before, but the car stalls at idle and experiences what feels like “fuel cut” after a few seconds of driving. Swapped back to OEM injectors with original map to rule out tuning, but the issue persists. Now suspecting an intermittent power or connection fault at the fuel pump hanger, possibly cause by the cleaning process.
