Depends on everything. Car, box, port area, woofers, tune, positioning, loading, frequency, car peak.

700 watts rated isn't an overly low amount of power.

I have just put a system together in a Toyota station wagon, 1600wrms and 1 x FCW-15 Does 146.7

[Big_Valven]

1600 watts is heaps. Even I've done 146s from 1.6KW...

[ryzaa]

Bobo has done 148ish from 1500w

Doug and I burped a 150 at 36hz off a clamped 1700w and one dead woofer.

As Big V said, 1500w is not really low power...

EDIT: disclaimer: scores set at a certain Easternats event dont actually count

Mad Ras(spelling?) on here, was doing 141's off 2x clarion 15"s and a jaycar 4x 100rms 4ch in his yellow pulsar, running 2ohm off a pair of the channels, which i believe is around 150rms per woofer...

as far as i'm concerned thats an AWESOME score off <300rms...


700rms really is plenty of power, and 1500rms+ is a tonne...

If you want big numbers off low power you need a high sensitivity subwoofer and a tapped horn.

I'd be thinking probably 300wrms-500wrms

Basic entry level mono amp or multi-channel

[Big_Valven]

I reckon it has to be <500w RMS rated to be considered "low power."

I find both of these very impressive

138.3db on a termlab with 1 x 12" in 1cu.ft sealed box off 400wrms... in an excel

[Spink!]

On a first run in an N15 pulsar hatch me and my friend did a 140.6db from memory, 2 old unknown kenwood 12's, 600wrms at 2ohm, 47ish hz 90mm single flared port, loading off the tailgate. With some tinkering should get it a little higher.

about the best part was the overal simplicity of madd_rass's install... it was very much what i would consider an "amature" install, not in a bad way, but you can tell when someone knows what they're doing, and when someone has just had a red hot go at it! and this was very much the latter, port was almost non existand, maybe 20mm wide, and i'm not even sure how long it was, i seem to think it was just the thickness of the mdf baffle....



(thats the port between the subs there)

i'm hoping Jason doesn't take this the wrong way, simply put i was VERY impressed with it, there was no real logical reason why it would work, but it did, and it got loud, and low too...doing the 141 at around 40hz...
