Okay ive got a Sony deck with alpine midranges (200w)50rms) and Pioneer 6x9 200w with a two 12'' rockford fosqate subs.What sort of amp am i looking at here.I want to run the subs above 50 rms each so say max 150rms each what brand and power do i look for.Santa might buy it for me (girlfriend and I) xmas money.would a kicker 600w do the job safely ideas?

well can't argue with u there strutto :cheers: ... anyways to answer ur question simply ... yes it does matter .. both power and size :( ... and yes brand does matter ... imho i'd go for a well known brand ... i mean i'd ask people who knows what look at then i'd compare them myself ... since reputation counts ... dont' go buying 600watt amp just cause it says 600 ... the quality stuff are usually rated lower and will go much higher ... but kicker is a decent brand ... u shouldnt go too wrong there ... personally i've got all jl and alpine in my car ... looks and sounds great :D

how much do u have to spend? If i were u, i'd want to wire the 2 12's in parallel, so they run at 2ohms instead of 4ohms, that way you can decrease the impedence on ur amp, and run more power into them.

a monoblock or a 2 channel amp would be perfect for this. You could easily put 200rms per sub this way from most amps provided that they are 2ohm stable.

Whats your budget?

budget is about $400 - $650 for a new amp.Should i even worry bout looking for a 2nd hand amp like a v12 etc or bad option.

if you want decent clarity, get two amps. one for the subs and one for the splits.

Size definately matters......but I wouldnt waste my money on some "name brand" shite either.

check out the Jaycar Response range. it's pretty bloody good for the price. Kicker performance on a BOSS budget.

boh!

Dont count out 2nd hand amps.

ppl who sell amps this price normalyl know what theyre talking about and r into car audio and take care of their equiptment very well.

I was in ur situation 2 months ago, I bought an audison LRx.400 2nd hand for $500. It runs 650rms at 2ohms, and 900rms at 1ohm.

Monoblocks r designed for subs, and theyre ment for driving very low loads, so u'll probably get most bang for ur buck there.

The alpine's r good too, mrd-500 is very nice. that can be hand for around $500 probably less with some haggling 2nd hand. Theyre 500rms at 2ohms. If u get a monoblock, u should run at 2ohms with ur setup, i assume ur subs are SVC 4ohms.

Cadence have a great selection of monoblocks too but im not really a big fan of them. PG's are in ur price range aswell, but i'd personally go the alpine v12's over them, many will argue with that im sure...

If u go 2 channels, i'd go an audison srx2s from www.webaudiodirect.com

its 600rms when bridged to 1 channel at 4ohms. thats 300rms per sub, its around $540 i think.

PGs are also a good choice again.. the vnet's are also good for the price they offer, the 2x100 is bridged to around 300rms i think at 4ohms, (not too sure on that) but theyre not 2ohm stable when bridged so u'll have to run them at 4ohms.

Definetly get 1 amp for subs, and 1 for splits, the loads and power requirements on the amps for those different drivers are very different, and it makes sense to have components specialising for those needs.

Bottom line, if it were my money, i'd go the audison srx2s (:600rms = 300rms per sub.. much better than what u were expecting to run!

    • pffft! My alignments are starting to take 3-4 weeks each. Bugger overnight - that would be a dream! Overnight is when I leave it on stands with the rear suspension in pieces, hoping I can remember where I was at when I come back to it. I have to set the car up on a level surface so I can get decent camber measurements, then try to set the RUCAs to the right length to get that right. Then I have to put the car somewhere else where I have enough room to set up the bumpsteer gauge (laser, paper, mirror), so I can dial out that. Then I need to go measure camber again because changing the tension arm length affects that also. Then I need to measure toe, and I can't do that to my own satisfaction at home, so I have to put it on an actual aligner. Then I have to go back and fix the camber again, and if that took more than a half a turn, decide if I want to set up the bumpsteer measurements again. I previously had the bumpsteer almost completely banished and then I started changing things again! And that's only the rear end. Not even gotten to talking about the front yet. And this has been going on in the context of me discovering a seized bolt in the LHR FUCA bush at the upright, hence needing total disassembly to replace that bush and the others that were not far away from the same outcome, replacing sphericals in the front end and making a mistake that resulted in needing to do it again, which is only half done right now. It's a selfmade nightmare. Only have self to blame, etc etc. But regardless, I am so complelely unable to utilise the services of a normal wheel aligner that I have no choice. I haven't found a shop in my city that does "race" alignments - and by that I don't mean I want my car to be set up for racing, but the set of adjustments that I have available and that need to be used to do the alignment are the same as you'd find on a race car. I haven't looked everywhere, but there doesn't appear to be the equivalent of the motorsport focused shops that are present in Sydney and Melbourne. And such an alignment would cost $300, and you only want to do it once in a while, and you don't want to find out that you have to replace bushes and bearings and such while you are spending that $300 so you have to come back and spend it again a week later. So I stay living in my self made nightmare for the moment.  
    • Well, yeah, obviously. But then you have a turbo with 270kW "design", meaning it will have the higher boost threshold and lag of a bigger turbo, but only doing the work of a smaller turbo. That's the suck. That's actually exactly where I am right now, because my stocker exploded and I got Tao to do a highflow for me. I got a low pressure actuator on it and don't push it past ~10 psi or so, where the stocker was being run at ~12 psi. it makes a little more power than the stocker did, but it lags like a bitch. But, if I run any more boost it starts to ping and the ECU goes into panic mode, which cuts all the fun, so it clearly needs to be tuned. But, until such time as I (which is not I, it's my bro-in-law) can actually get the dyno working again, and get some injectors, and do all the swap over of those and the R35 AFM, I can't attempt to use the turbo the way it really deserves to. So what I have now is something that drives worse than what it did before it filled the cat with little pieces of turbine. I will tune it eventually, and probably only push it up to ~250-270 rwkW, which is pretty close to the max for that highflow anyway. I would imagine that by getting the tune right, and with newer betterrer injectors, we can probably make the boost come on a little earlier than it does now.** And if I do not think that the top end reward is worth the low end sacrifice, I will sell it off and convert to a G30, because the smaller ones of those come on boost very nicely on a 25 and make more power than I realistically need or want. The only reason I didn't do it at the time the turbo blew up is that I wasn't ready to sink a lot of money into an Artec manifold, reverse rotation turbo, the AFM and injector upgrade that would have been immediately compulsory, and the dyno was being problematic.*** It was easier and faster to just put the highflow on. And then, as I mentioned in an earlier post, even that is not "easy", because Tao's highflows use a shorter core than the Hitachi, so the compressor housing moves backwards in the bay, necessitating that all of the pipework had to get modded. ** And maybe just maybe, check the valve clearances and put new shims through, because I have recently seen firsthand on another motor that sloppy clearances on the shims can cost a lot of effective timing and lift and really slow an engine down. 3S-GTE in a Caldina got new shims, closing the clearances from just above the max to right down near the minimum, and it is a massively different car to drive. On boost the better part of 1000 rpm earlier!
    • ooooooh so this is where they get posted  Was at a wedding that day anyway, but the next one I will be there for SURE.
    • @PranK, why do we have this restriction? Because photos are the first thing that gets asked of new people on the forums. Do the spam bots post photos if allowed?
    • How do you rate the clutch @joshuaho96? Sometimes I wonder whether it's genuinely very driveable or whether I just feel that way because it cost a good chunk of money. Most recently when seeing the guy at the tyre shop struggle to move the car...
