Well ive rushed into buying a DVC 4ohm Alpine Type R 500 rms(without thinking) and have been searching up the matches and the ohms required.
The amp i was planning to use with this sub was the Soundstream TRA 560.2 specs are :
Number of channels: 2 Output RMS @4 ohms: 140W x 2 Output RMS @2 ohms: 280W x 2 Output RMS bridged @4 ohms: 560W x 1
Is it possible to run the sub efficiently on the TRA 560.2? Or should i start looking for another amp
Thanks in advance, ironik
Sadly that amp just isn't a good choice for the 4 ohm DVC Alpine you have. You could only wire it to get a mere 280RMS (if that since the amp isn't CEA certified). With that little of power you could easily push the amp into clipping, which would drastically reduce the life of your sub. You might be able to use that amp without pushing it so hard to cause clipping, but I highly doubt you'd be satisfied with the output of the sub. Really the only choice I see you having is to get a different sub or amp.
If anyone else can offer better help, please do.
Ah well, might sell my amp and look into getting another then
Thanks
The published specs on the amp are about ideal for a Type R DVC-2-ohm sub - any chance you can exchange it?
If not, your best bet is to wire your sub at 8-ohms and bridge it to the amp like this:
The amp should put out 280W at 8-ohms, but that's an estimate. That is 56% of RMS and CF's guidelines are 70%, but I've also seen them sell systems (entry-level) as low as 41%. It's not ideal, but it will work.
I don't see that you have much to lose by trying it - just don't turn the gain up to the clipping point.
Hope This Helps!!!
2002 Ford Focus Sony CDX-GT410u Sony XT-100HD HD Tuner Stock speakers, no amp, no subs
Yeah ill see how 8 ohms goes, cant trade it for a DVC2ohm Type R because i bought it 2nd hand
I will try swap it if i can, amp is for sale now lets hope it sells before the sub arrives
Okay - well, you might be able to swap it pretty easily. (I'm sure there is someone out there with a 500W@2-ohm mono amp that bought a DVC-2-ohm Type R without thinking about it and is in the same boat as you are).
OTOH, I'm not sure I wouldn't try it with your existing amp before I gave up on it and sold it.
Yeah, im trying to swap it with someone, just need that someone to contact me :P
"OTOH, I'm not sure I wouldn't try it with your existing amp before I gave up on it and sold it." <-meaning give 8 0hm a go?
Ironik:<-meaning give 8 0hm a go?
Correct - nothing to lose that I can see - just make sure you don't turn the gain high enough to send it a clipped signal.
I would buy a
Alpine PDX-1.600
It puts out a clean 600RMS at 4 ohms.
A little overpowering for the type R specs but they are VERY under rated. you can run 750 RMS to a type R without any problems. Just don't turn it ALL the way up for long time periods.
If he doesn't swap subs, he needs 500W RMS at 2-ohms. The PDX-1.600 will do that also, but most amps won't.
Well ive scored this amp here : <Performance Teknique ICBM -1992 Mod Edit: Per our linking policies, please link to the manufacturer or to the Crutchfield site whenever possible. thanks. > for very cheap , just wondering how i would wire 1 "Alpine Type R 12" DVC 4Ohms" to work using 1 channel of "2Ohms 400wrms" on this amp.
1000 watts
Something about that's amp's specs doesn't sit well with me. The amp is 400Wx2@4-ohms which is fine, but it is only 400W Bridged RMS power (at 4-ohms presumably), that should be about 800W - maybe it's a typo on the competitor's site. (PT doesn't even quote RMS on their site, which is a bad sign).
Really, the best way to run a two channel amp is bridged at 8-ohms as above - that one should still do about 400W RMS, which is good.
Alternately, you could run the sub with the coils in parallel for 2-ohms and only use one channel of the amp with a Y-connector on your RCA's, but that is more complicated and usually won't gain you anything.
aw im going to avoid that amp.

didnt end up purchasing that last Performance Teknique amp, settling on this http://www.trademe.co.nz/Browse/Listing.aspx?id=253232102 which is 400 rms x 1 at 2Ohms.
whats your thoughts on this tigerheli?
Okay - that should work out a bit better for what you are looking for. Boss has a bit of a reputation for being "generous" in their specs - i.e. it might be less than 400W RMS, but it should work fine.
You will want to wire the sub coils in parallel like this:
