£100 decent amp with sub out? Any amps with powered iPhone?

[torqueofthedevil]

I have a nad 310 amp which is about 15 years old but does the job. Or it did. I want a decent sub but there is no sub out socket. From what I've read it's not easy to connect a sub to the speaker outlets on the amp so I'm thinking I need a new amp? Then would need an active amp? Only want to spend £100 or so.

Also, is there an amp that has a powered I phone connection? I suppose a USB connection would work. Allowing you to power / charge your phone while playing music off it?

you probably want a home cinema amp for these features, most will have a sub out and many are coming with usb sockets although if they'll power an ipod I don't know. Some def do but prob newer and more expensive ones than £100.

Not sure if they'll sound as good as the Nad, not that I've heard that particular model but as a comparison, I use anigh on 20 year old Kenwood KA3020SE amp (very good in it's day for it's budget which was around £200) with some Mission 731 bookshelf speaks and I'm pretty sure it sounds better than my Yamaha DSP-AX750SE Home cinema amp which was about £500 in 2004.

No need for a new amp. Most decent subs should accept a high level and low level input. A low level input is probably what you're thinking of, the sub output on an av amp for instance. But you can use the pre-out on a stereo amp (if you had one). The high level output, it the connection to the speaker terminals. No reason why this wouldn't work, the cable will just plug into your existing banana plug terminals of your amp, then your other speakers just piggy back into these.
(I assume you don't have a much older variant of this amp with spring clip speaker terminals).
Once plugged in, just tinker with the volume and crossover dials on the sub, so it matches the volume from your other speakers, and give a nice smooth transition of bass where your other speakers fall off and the sub takes over. A sound meter or the free Room EQ app (from Home Theater Shack) can come in really handy, but you should still get it sounding good just by ear.

As for plugging iPhone in, just pick up a cheap Apple docking station/charging cradle off ebay, then feed the 3.5mm jack off the back of this into one of your amp inputs. Some of these cradles also include a little remote for your phone too, which can be dead handy. Picked up on myself off ebay for £25. Just make sure you pick one up with the necessary adaptor to hold your version of iPhone. I'm happily using my old iPhone 3GS for Spotify into an Exposure stereo amp.
