Amp suggestion for 2x 12" subs?

[SKY000]

hi gents!

i currently have an amp in my booty which is powering 2x 12" phoenix gold subs. they're not top of the range or anything - but, the amp is rewted badly and i need a replacement. it just came with the subs when i bought them off a mate and i'm guessing it's pretty sh1t anyway.

i was wondering if anyone can tell me what would actually be good to power these subs. there's heaps of information to read on powering 1 sub with an amp, but i've not come across anyone powering 2 subs with 1 amp. i have the rest of the system running off another (smaller) amp so i don't need to worry about that..!

do i just want a 2 channel amp? or a bridged 4 channel amp (is there even any point in that?!) i'm not even sure what power rating i need. some of them say "1000 watt high powered..." and are cheaper than something that says 250w. so i'm just a bit confused :Oops:

i somehow found some stats on it in case they are important:

Subwoofer Specifications

Size: 12 inch

Rec. Sealed Box Dims: 0.60 - 1.20 cu.ft.

Rec. Ported Box Dims: 2.00 - 2.60 cu.ft.

Free Air Usage: not recommended

Sensitivity: 90 dB

Frequency Response: n/a

Recommended RMS Power: 300W

Peak Power Handling: 600W

Impedance: 4 ohms

thanks for reading this far..

thanks for the info, makes it useful

whats ur budget?

my subs that i was using are similar, 4ohm and 300rms.

if u can afford it, get a monoblock and run the subs at 2ohms. this way u put more power into them, u run them in parallel instead of series.

this would be ur best option

the next would be a 2 channel, and bridging them to one channel (monoblock coming again..)

the last option, which i wouldnt recommend, is a 4 channel and bridging them to 2 channels, and running a sub off each channel. This would mean ur running each sub at 4ohm and most likely, underpowering the sub.

its better to overpower a sub and be careful with the gains.

what i got was a 2nd hand audison lrx.400 monoblock for $500. it puts out 400rms at 4ohms..but 650rms at 2 ohms. that means each sub is (was) getting 325rms.

things to look for when getting ur amp:

make sure its 2ohm stable if ur gonna do that.

look at the specs for 2ohms and not 4ohms if thats what ur gonna run it at. make sure these specs are for 12V not 14.4 or some other voltage that u cant produce.

dont look at max power on the subs or on the amp..it means nothing, only look for RMS at 12V.

hope i helped u a bit.

There are many amplifiers on the market that will run your two subs.

You will require an experienced audio buffoon to syphone through all the 'power figures hype' and give you the real answer.

Some of the amps I often install and remain big fans of are:

Audison LRx1.400 (RRP$899)

Audison VRx1.500 (RRP$1996)

Boston GT-28 (RRP$1399)

Zapco 1100M (RRP$1699)

Tru-Tech H-1 (RRP$2399)

There are others but without a budget it gets kind of hard...

Alpine MRP-350

Monbloc Amp. Available at any good car audio dealer. I've got it running 2 x 12" aplines in my r33 boot and they kick ass

JL audio momoblock amp, what an animal.

i belive the best amp for those 300rms amps would be the kicker kx600.4 cos then it would run 300w to each channel(sub), this atm is on special for 699 at audioCom

hope that helps
