is the company Lanzar


any good

 

I have never owned a Lanzar product. I do know that they are made by Pyramid though and pyramid is a flea market/pawn shop brand. I wouldn't put a pyramid amp on a tricycle.

 

I have used almost exclusively BOSS amps for the last 10 years, and have never been disappointed with any of them. Always used MTX Crossovers with them.

 

yes lanzar is fine. its one of the best for the price it wont put out as much power as an class d of course but for components and a basic system it is fine. You really dont want to over power your sub with an amp, that wouldnt make any sense. thats how you blow fuses in things. a sub doesnt ahve a fuse and will result in a blown sub. if the amps is a 500 watt amp and the sub is 600 then you will have no worrys about pushing to many watts to it.

 

i have two mtx

 

Sorry man, I disagree with Choppa. I have been installing systems into cars for 15 years and competing for 10. DO NOT UNDERPOWER YOUR SUB. Underpowering a sub will destroy it quicker than overpowering will. If you don't believe me ask someone on these forums www.the12volt.com Also, you do not blow fuses because your sub is being overpowered. I have heard that LANZAR is okay, if you stick with their optidrive series.

 

Thank you for stateing that every time i tell someone that they think i am stupid, and have no clue about systems.

 

no one said u were stupid i have always been told by people in competitions we go to and by the guy who did my system who owns an audio store that you dont want to over power a sub then u have an easy chance of blowing it if the sub doesnt get to its full potiential your chances of blowing it are MUCH lower. thats y even home systems have a 50 watt sub with a 75 watt sub thats jus wat i was told and see i may be wrong. but wat ever makes a system beat is fine with me

 

Lanzar is the crappiest brand ever!! dont be cheap when it comes to car auio. Once i got american legacy speakers and they sounded REALLY GOOD, if your gonnaa go cheap go with that brand instead of Lazar...

 

I haven't done any car audio since 1988, but I am a huge home audio buff and too little power will blow a speaker before too much power, and it's not due to volume (although the louder you play it, the more chance you have). It has to do with clipping. You have peaks in music and if the amp cannot push the speaker during a peak, then it will "clip" or distort which can cause a speaker to blow.

Here's a quick excerpt from a website I found that may do a better job of explaining:

Why do we keep 'blowing' speakers?
Some people mistakenly buy amplifiers rated equally to the average rating of the speaker. What then happens is that they push the amplifier into clipping (either constantly or regularly) and it is the clipping that destroys the speaker. Clipping is distortion. While distortion in higher frequency drivers is easily noticable distortion in woofers is not so easy to detect. This is especially true in noisy environments or if the engineer is not as experienced in what he is hearing.
A bigger amp with clean headroom is much better than to be under-powered.

Another problem is over-excursion. This can go back to the topic of EQ misuse (See the guide on this site). It can also be a system alignment and protection issue.

If a speaker is being driven below it's operating range then it will likely overheat and/or literally over-extend itself in its frame. It will then have to be replaced. To help eliminate this most channels on the mixing console can benefit from use of the HPF (sometimes called Lo Cut Filter). Things such as vocals, guitars, cymbals, etc. don't generally have energy in that range and can easily benefit from the cut.

Feedback is also a speaker 'killer'. Besides just downright unpleasant to hear it places undue strains on the speaker if left unchecked.
