yes i know about rms and pmpo and max and junk, all power ratings are in RMS
sub (responce titanium 150w) 4ohm
amp (kenwood monoblock 1000w max) 300w x 1 at 4ohm
so im in the process of upgrading my sub, i thought was 300w but is only 150w
so my question is am i going to damage my 150w sub (yes if put up too loud)
but more important am i going to damage my new amp ???
if im only going to damage my sub by turning it up i'll just make sure i dont go over 1/2 vol and if i kill it i'll get something else,
BUT
if im going to damage my amp what subs people recomend ? on the cheap side of things,
There is a risk you may damage the sub, but the risk would be greater if it were the other way around. i.e amp 150w, sub 300w. Reason being the amp would clip the signal at maximum volume and the sub is effectively fed a DC signal.....this will burn out the sub in no time.
In short, they'll be fine. Crank it up!

During normal operation your amp will definitely be completely safe. If anything, it's actually better to have a bit of excess amp power on tap so that the amp never has to work at its limit, and so that it has good headroom on transients.
But - one situation I'm not sure of - If the sub were to blow while the amp is cranked, there may be a possibility of damage to the amp. I think it would probably still be ok. Would be a different story if it was a valve amp - they can be damaged it you run them without a load (yours isn't a valve amp though).

I hope you're not making the dangerous assumption that 1/2 volume on the dial will give you exactly half power from the amp, ie a maximum of 150WRMS rather than 300WRMS. That's not how it works.
If you ever hear any signs of strain from the sub (either distortion or suspension bottoming out) turn it down straight away. If you ever smell a burning smell, don't just turn it down, turn it off before the voice coil or assembly glue burns.

Whenever that question gets asked here, the answers are pretty predictable. All the Alpine fanboys will carry on saying that nothing compares to Alpine, and one or two people will tell you that the Kicker L7 is the best thing in the world. If you're lucky, you'll get a sensible answer from someone. I'm not even gonna try answering that one.
wats your definition of a cheap sub tho mate???
KENWOOD have some good subs for the price they are, a mate bought 2 kenwood subs and an amp all in one package incl. box for $700 but it really does depend on what 'cheap' is
I had a friend in the same situation(going back a few years), and he did same thing and placed a kicker amp parallel with a standard kicker sub. I think it was something like 500watt amp to a 300watt kicker. Anyway it sounded great until a few weeks or a couple of months later the kicker sub started making a popping sound when the bass hit.
Here's a video of a person running a 1200rms amp with a 700rms subwoofer. Watch it smoke!!!!

As stated above, far better to have more power in the amp than the woofer rating than vice versa.
I'm bored and will offer my opinion on subs
People get hooked up on brand names, in basic terms you get what you pay for. But as for what sounds the best well that can depend on a number of things, is the encloser suited to that woofer? how do you like your bass? I personally like my bass firm, accurate and punchy with as flat a freq response as possible so something that sounds good to me may not be what you're after. I'm not swayed to one particular brand (though i am swayed away from a couple) but the sub setup that i liked the best was a couple of boston pro 10's in a sealed enclosure. Have a listen to a few different subs and make sure they are in enclosures that were designed for that sub, get a feel for what box you like (sealed/ported/bandpass etc) Then once you buy a sub, If you've got the time screw a few MDF boxes together at different volumes/port sizes/lengths. A well designed box can make a $150 woofer sound a million bucks and unfortunately a poor box can make a $1500 woofer sound like junk.
Some original photos have not been recovered yet.
Why not save up and buy something that will actually last and you wont need to change months down the path something like Digital Designs or Hi Fonics. But if you want cheap dirty loud bass get a Sony LOL

with the burning smell you are actually best to turn it down than to turn it off.. the burning process has aready happend, so by turning it down especially with high output subs as well, you reduce the risk of seizing the voice coil. which is more likely to happen if you turn it off
