The 4x100 amp of which you speak is a good value for money amp(make sure you get this one and not the others).

I have had no problems with the 2 amps that I have installed for mates.

There is a really good review of them in one of the import magazines(I forget which). They produced gobs of clean power in a lab test and heaps of people have praised them.

I'll give Jaycar a big rap anytime.

I've done a heap of installs in mates car using Jaycar gear and its pretty good quality and none hav had any problems this far.

more so a value for money thing for me then anything else, and although i dont run em (I use alpine) They're excellent value 4 money and get raps from all the audio mags.

Hippy,

I talk from experience.

I think if you haven't used them, don't diss them until you do =p

I use all "quality" components in my system, Utopias splits, Rockford Fosgate amp etc.

If you can hear the difference between the two simlarily rated amps I will eat my hat.

Sure the internals of the Jaycar MAY be a little cheaper than "quality" amps, but as most of the people already have said there pretty reliable.

What is a quality branded amp anyway?

Pioneer? (laugh)

All good feedback so far so.... JAYCARS it is then!!

thanks guys

much appreciated.

One other thing, I was reading some specs on the jaycar amps and came across "@ 2 ohms" or "@ 4 ohms"?? Whats that all about? Can anyone explain?? (as you can see i'm still a virgin when it comes down to audio gear..)

Basically, (i am mean basic cause i'm not an electronic expert) most normal car speakers run at 4 Ohm, which is a loading which is the head unit (or amplifier) sees when driving the speakers (ie playing music). Normally, with a two channel amp, you would plug one speaker into one channel and a second into the other channel and that setup, the amp would be powering the speakers at XY Watts x 2 channels @ 4 Ohms.

2 Ohm loadings can occur in a variety of ways. You can conenct multiple drivers (speakers) to one channel - not necessarily two either or connect two or more voice coils to one channel. This changes the load placed on the amplifier. This makes the amp work harder and some older amplifiers can't handle the extra load. It's best to ask your audio place how you can best wire up the amplifier to make maximum power if you are unsure as incorrectly wiring up the amp may result in the amplifier seeing too much load and shorting out or melting something.

I'm sure others can explain it better than me but as far as a basic explanation goes, I think that's right.

Bare in mind a few issues when talking about Jaycar amps as they have been tested to output their rated power but not much more at all.

There are also numerous other issues to consider when buying a Jaycar amp too. The Jaycar crossover quality is known to be "less than average" and sometimes require the user to utilise an external one. They don't have much internal capacitance, the damping factor isn't terribly high either and their THD is disasterous when they're loaded down (although this will not bother subs too much). As far as their specs go, they meet them. But when other important factors are considered, the "more expensive" amplifiers (such as Boston and Audison) provide benefits in all of these areas.

Actually,

Pioneer not long ago had amps that I wouldn't touch with a 10ft barge pole.

I'm not sure what there like now.

Sony are pretty good, my friend has a Sony 4x150w it is HUGE and performs pretty good aswell.

FYI Pioneer distribute Rockford Fosgate, I wouldn't be surprised if Pioneer bought them out.

my mate bought a jaycar amp. not sure of the model to power his frount and back spits, after his install (which i will add is probally the cleanest install i think could exist, i mean its insane the effort he went to) it had a rather annoying hiss. he took it back, they swapped it and the one he got did the same thing. he ended up looking arround on the net and found that this amp is known for doing this.

this bit of shit to add to the pile.

    • The German place in Cabramatta was rock solid, fresh pretzel cooked to order back then. Then it went all quiet, after all the poker machines were removed, then I believe it closed for good. I did drive past the other week and noticed outdoor lighting a big screen, but no idea what is there now.  
    • Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.
    • I would say no, why, because my daughter, who also lives in Goulburn, hasn't recommended us going there Pity, as we miss all the German joints around in Sydney, actually, the restaurants are the only thing I really miss about Sydney, and a special mention to Ishibanboshi at Bondi Junction, their Kara-age Don is heart cloggingly deliciousness (always added a special boiled egg...or 2) 😋 
    • Does that German restaurant still exist in the old place out the NW end of Goulburn? When I say "out the NW end of"...I am really being vague. It was 1997 when I was last there, and the only point of reference I can recall is that it was on the opposite side of the main drag from the big merino. And when I say "opposite side of the main drag", I don't mean "on the main drag". It was either a couple of streets back from there, or might have even been out in the sticks a bit further. Was an old farm building or mill or somesuch. And when I say "the big merino" I might actually be thinking of a completely different part of town, because I just looked on maps and the big bugger is not where I remembered him to be! The food was good, consisting largely of various German mystery-meat sausage/loaf things and kartofflen.
    • So while the second sentence is completely correct and the whole point of the conversation, the first sentence bears consideration. If this bloke is just hoping to throw big turbos on and drive it around, because there are no helpful facilities at all in his tropical paradise** then he likely has zero chance of even knowing what the TP is on the last column in the stock maps, let alone know whether the ECU is operating anywhere near it or past it. So the point is very very moot. And, per what I said before, at stock boost on those turbos, you may well be off the end of the map. **I'm just back from Vanuatu, so I know exactly what small Pacific nations can be like wrt paradise without requisite facilities. But it's not even that simple. I put a high flow on my car and had to drive it around without a proper tune because of the lack of opportunity*** to put the bigger AFM and injectors into it to allow it to be tuned. I had to turn the boost down to less than I had before, and back off the boost controller's ramp, because it was exploring parts of the map that it didn't drive in before, and really couldn't access for tuning on the dyno either, and so was pinging. It was still well within the last column, because when I first**** set up the Nistune on the Neo I rescaled all axes of the maps to give some more space to explore. ***Family dyno was broken ****This was 13 years ago, and the TIM thing wasn't a thing then and so TP would definitely grow when pushing past the stock tune's limits.
