ampp!!?

[scolari]

hey guys just need some help with an amp decision anyway i am buying soon an alpine type r do you reckon the cadence amp ZRS-1502
link : ZRS-1502 - ZRS SERIES - Cadence Sound Systems, Inc.
would be a good amp to power it? i could get the alpine pdx 1.6 but would there be much difference between them? the cadence can go 1 chan 600 rms on 4 ohm where as the pdx can go 1 chan 600 rms on 4 and 2 ohm
i'm only running one sub and the pdx is a good $250 more so is the cadence one more suitable seeing they are both the same rms

[colk]

As far as I am aware the Alpine Type R is DVC (unless there are two models?) this means that if wired in parallel it would put a two ohm load on the amp. The Cadence is rated to be safely run at 4ohm when bridged, therefore I would go the pdx purely because it is rated to 2ohms.
There are also many other options out there for amps, maybe just shop around and buy as much power as you can afford for a Class D monoblock rated to run at least as low as 2 ohms. Most class D Monoblocks are designed to be run at 2ohm at low frequencies all day long, well two an extent

[scolari]

there is 2 models the SWR-1242D which is 4 ohm and SWR-1222D which is 2 ohm but u would recommend 2 ohm?

[garfa]

i would recommend which ever wil suit the amp you like most.
there is no diffference in SQ or SPL between a DVC or SVC.
i would probably be more loking at a class d amp simply because it is more efficent than ab.
next have a look around, goto jb and where ever else, they might have something decent at a good price. also have a look at qulity car audio shops. they can offer HUGE discounts if you know what you are after. when i was having a look at a local car audio shop, I found a nakamichi 4 channel amp at less than half price. if i had 550 i would have snapped it up. (i bought a 22inch lcd instead to ease the pain!)
also if you remember what you need in terms of power then you can get the sales person's advice. i would not recomend talking to jb and the likes guys, they seem to not be too good at it IMO.......

whats sort of cash figure can you spend? we might be able to help.
(also remember its a sub amp so quality is so-so. no need to buy a great amp, unless you have the coin.)

[scolari]

well i'm looking to spend around $500-600 i might pop down to my local car place called fhrx studios just across the road i've got stuff installed there but never actually looked at there gear but if anyone suggest anything in that price range it would be great

[bezz]

lol fhrx is one of the biggest car audio specialist stores in australia. if i lived across the road from it i'd go there and only there

[Ra1d]

thought about an option audio class D mono? 1500w@1ohm and i see them for under $500 usually

[scolari]

ra1d you must be wrong or you see 1500 watt max because the alpine is 600rms for $650 and thats a mono and i've seen alot around the same price and plus these subs aren't 1 ohm seeing i only have 1 ohm and i've mentioned that

[Ra1d]

for your reference... Option Audio

max rating isnt worth the paper its printed on... i know what power these amps are rated at, and how much they cost coz i have one mate :P i got it for a good price but have seen it priced reasonably elsewhere. i have it loaded @2ohms but it adequately pushes 2x400w dvc subs for me. its unfair to compare a lot of different brands to alpine, coz it generally is pretty expensive albeit good quality

[scolari]

yeah i agree it is quite expensive but i've been looking around and it seems most brands are around this price range. Just wondering if i do get a 2 chan amp and bridge it is there any pros and cons between it and a mono ? and what do u guys think of the brand soundstream?

[garfa]

ok mate, some people will disagree with this but generally most main stream brand will be priced closely for comsumer competition. alpine, rockford, clarion, pioneer ect... they are all slightly directed to a certain product focus. rockford stuff usually will be more power, wrms / alpine is more visual with a focus on quality / pioneer are probably one of the more rounded companies and they do a good job of supplying the power with some quality.

really though, you are powering a sub. its lower frequencies and the distorsion and hence quality is harder to recognise. you will need to get power to the subs with as high a possible effficency.

please dont take this personally, i want you to be happy, but spending 500-600 on an amp for a type R alpine is silly. spend as little as you can on an amp for such a sub. spend the resat of deadening the boot and car. you will get a better sound from that than spending big on an amp worth 150%-200% of the subs price.

since it is only 500Wrms i would not be too worried about what class it is.
why spend extra on a 1 ohm stable amp? why even suggest an amp like that. it is overkill.

just get an amp. go jaycar if you want to spend little but retain quality and reliability.
spend a few thousand on a class a amp handcrafted in wherever, but there will be stuff all sound quality improvement over something much cheaper.

[scolari]

garfa so your saying i should buy Precision Response Car Amp 2x150WRMS
bridge it at 4 ohm and run it 1 x 500 wrms? is that alot of car installers i have spoken to have said to try and get a stronger amp at around 700-800 rms what do you think?

[Ra1d]

yer something like a 1500w mono is definetly an overkill for your sub, but it will power the sub effortlessly and it will leave the option there to add another sub if desired in the future. i think you really need to consider what you want now and possibly into the future as once you add bass more often than not you will want more and more. if you think the 1 sub will sort you out and you want to stick to a realistic budget, def get into something suitable from the response range

[scolari]

i never said i wanted a 1500 rms mono i said around 600 rms i dont think i will want to upgrade seeing i used to run 2 pioneer subs not exact sure of wattage or anything just know it was $600 in a ported box from jb. i'm thinking i might buy the 2 chan and bridge it that way if i do want to upgrade in the future i can use it to power splits when i buy them and upgrade to a bigger mono. i think that might be the smartest solution for now

[garfa]

well the type r is rated to 400Wrms so 700-800 is a lot of extra power not getting used.
all i was saying is that there is no point in buying a $50 sub and a $1000 amp. (thats a bit exaggerated, but you get the point)
which 2 channel are you speaking of, response or cadence?

[scolari]

the cadence sorry only because i like the look of it and will suit my custom boot better haha
