What amp would go good with a "15 sub?

[nozerider]

I am planning on getting the Alpine 15" sub, and was wonmdering what type of amp would be good. Any recommendations on brands and watts necessary would be great.

 

[bdogg23]

i think it all depends on how much the subwoofer is rated at.. like mine, i have to 12" at 250W a peice so i got a 500W amp... i personally like rockford fosgate but i heard xtant is good too...

i have 2 15s with near 500rms each from fosegate amp...expo5.0 has 15s with a 1501d...u gota be ALOT more specific. like maybe post specs of the sub u have? might make things a bit easier

Ones that come to mind are a HiFonics Brutus BX500, JBL PowerValve BP-600.1, MTX Audio Thunder801D (at 4 ohms), Avionixx AXA 600.4, Tsunami DB1100 (Kinda overkill at 1100 w RMS @ 1 ohm, but still only $220!), and A Phoenix Gold 500.2

That should get you started

my friend has 2 of those 15" Type R's, he has it powered by a 1501d, i must say it sounds good, the the dang back window didnt move in and out and the cab rattle :fire:

http://www.mainstreet-audio.com/phoenixgold/phoenixgold_amplifiers.shtml

That page has the one I spoke of for $300...

 

[nozerider]

OK, here's another question, given the watts of the sub, what is the least watts I should get in an amp for it?

 

[XplorerKid]

Is that MTX?

yea the MTX one............ i think its the 1501d(w/e there 1500 watt one is)

 

[BBQ_HotDogs]

Alpine suggests getting the Alpine MRD 500 amp. I have 2 of those amps. Great amps. Get 1 and it will push that sub till the cows come home and you will be happy you did.

 

[Fhantazm]

Those subs are NOT very sensitive (86db) and the manufacturer reccomends at LEAST 200watts RMS (100watts per coil).

 

[nozerider]

Do I absolutely need to buy a seperate amp for the sub? Or would it run off my 4 channel MTZ I have now?

 

[Fhantazm]

Whats the RMS wattage of your current amp?

 

[GooseR]

Yea, id go with the MTX THUNDER 1501D. Go to www.cmttrading.com and then go to amplifiers, then to mono block, then it should be the first amp on the second page for $359.00 . Ive bought from them before and they are pretty good(not scammin ya). good luck and have fun,.

 

[Nate1]

I dunno if I would do that. The 1501D would only be good for that alpine if run at 4 ohms, which means it could be doing a lot more work. It is a good choice if he plans on getting another 15", but otherwise, it is money wasted. I would look at the 1 ohm ratings of amps and drop down that low with a 1 ohm stable amp rather than get a 500w @ 4 ohm amp that probably could do 1000+ watts.... which you don't need

 

[nozerider]

Here's my current amp, its pretty old

Do you think i should just get a new 4 or 5 channel amp to power the whole thing, or should I use my current amp for the speakers, and get a mono channel amp for the 15"

 

[nozerider]

Hows this mono amp?

[expo5.0]

that amp would not be a good choice either, same situation with making power at the wrong load.

you could consider a 502 mtx amp, please don't pay crutchfield's prices though
