i need help !

ok but is it a good amp and will it blow the db212-2's all to hell is it to much power?

PoweredByDodge

its a decent amp - its not the creme de le creme, but its decent... and if you keep the gain down, no it wont blow them to hell.

Just do not go with the Jensen subs. When I sell them I know they are going to get returned.

98thumpin

ok point taken im going with the db 212-2. stupid question but what exactky is gain and what does it do? is it like volume or something?

neomagus00

no, for the love of tim, no... gain is NOT volume...

simply put, the gain knob matches your particular amp to your particular HU... it sets the amp to read a particular voltage (mine is 6.5, if i remember correctly), and amplify the signal accordingly, that's ALL... it's not used to make the music louder, or make more power, or anything else...

Well - you need to qualify that... there is absolutely nothing wrong with using a gain dial as a limiter.

You can't get "more" power out of an amp by dialing up gain, becuase it will just clip at its 'highest stable power output into that load'. But you can **** power output.

For example... if you have a 900 watt amp, but you would only like to get 700 watts out of it... you can set the gain below where you would normally set it to achieve the full 900 watts.

many people have used this 'trick' to make use of large amps (which they already bought before) on not so large speakers that they just picked up... or to 'match' the sound output of various speakers (example, bi-amping components and dialing down either the mid or the tweet to make them 'blend' properly).

It can also be used to blend amps together better. Say your sub amp is overpowering your mids/highs, turn the gain down a bit to match.

it's a non-denominational, non-offensive (here, you guys would read 'liberal' ) outburst (and what's wrong with me would take days to explain )

and yeah, i forgot to mention you could turn it down, good point...

98thumpin

ok so its like a limiter to use the helps adjust the power output of the amp so u dont blow ur speakers in other words. what is meant by the term bi-amping or bridging?

neomagus00

bi-amping is when you use a separate channel of the amp for every speaker, whereas normally for components you use one channel, then an external passive xover splits the signal

bridging is something totally different, where you combine two amp channels into one for more power (with a cost, of course)

1996blackmax

The cost for me is not that bad .... If I wanted to go this route.

MacLeod

Other than more distortion, better chance of clipping, more heat and so on.

1996blackmax

Not if setup properly

98thumpin

lol ok gotcha, another dumb questions what is meant by the term clipping, and also can you run 2 amps off of the same power cable?

neomagus00

clipping... here is a good short explanation

yes, you can run 2 amps off the same power cable, assuming you have a distro block IF AND ONLY IF the main feed can handle the currrent you'll draw over the proper distance... see this chart...

98thumpin

good information mainly clipping is when your asking your amp to do too much.

ok i need some help ok? im limited to oval speakers i noticed i can get mmc speakers in oval shape with an external crossover.

You could also go ghetto style like Mac .....

Get them. The MMC690 is the best coaxial speaker on the market!

Yes because as we all know, if you dont use a distribution block your system wont function. Plus it wont look as cool and that is also very important to the sound. Its a damn wonder Ive won so many competitions since my power wires wont work. But since you cant see them anyway just pretend there is a really fancy, gold....no...diamond plated distribution block under the carpet. Boy doesnt my system sound better already! :rolleyes:

1996blackmax

No need to get uptight :rolleyes: . I believe that taping the wires together is also a safety issue, but that's just me.

That is a pretty tall order, there are other coaxials out there that I would use.

98thumpin

ok i have a 1998 ford crown vic, it takes oval speakers the db 570 and the db 690s are what fits. but u heard the mmcs are better speakers. or for the money are the dbs better.

1996blackmax

The MMC's are higher up the line. If you can give both a listen, then see which one you like. Maybe the improvement in sound over the DB's may not be worth it to you.

You can also make an adapter plate for the 6x9 openings...

How? How is stripping the ends off two wires, splicing them together and then taping them up with electrical tape less safe than sticking one end in a dist block and **** a nut down to hold it in place? Its not. Ive been doing it for 15 years and have NEVER had any safety issue whatsoever!

Plus, I bet ya I could pull a wire out of a dist block before you could pull apart 2 spliced/taped wires. Im not knocking distribution blocks as they make things look better and neater but they are no more or less safe or funtional than PROPERLY splicing/taping.

Im not getting pissy about this but everybody seems to be bitching about it but so far, nobody has told me why this is such a horrible thing.

And yes, saying the MMC690's are the best coaxials on the market is a tall statement, and after having owned a set for a couple years, I stand by it.

1996blackmax

I just told you why I don't think it's a good idea...

I actually had some amps fry on me due to this when I was in high school. I thought I had spliced the wires and taped them right, but the smoke in my trunk proved me wrong.

How much tape do you have on the wires? Is the tape equivilant to the amount of insulation that the power wire has?

I work in the medical field and there are many people who do not use eye protection in surgery, never have. They have been lucky enough not to get anything. I always wear eye protection to avoid blood splatter in my eyes. There have been plenty of times after a case where I see specks of blood on my goggles (meaning this blood would have been in my eyes without the goggles), this has happened with patients infected with both HIV, and Hepatitis-C. Even some with necrotizing fasciatis. I just do not like to take chances when it is so easy to go the safe route. I apply this to many of the things I do, including car audio. I just think it's safer to use proper power connecting equipment, but that's just me bro.


About the MMC690's, I know this is a Polk forum, but let's be open to other things that are out there.....

98thumpin

ok well ive been to virvuit city and i heard the db speakers and yeah they sounded better than the others but the didnt have the mmcs hooked up im going to try to go to best buy tommorow just to see if i can hear them there. what is the major difference between the db line and the mmc line. besides price and looks i know the mmc's look cooler. id love to have the sr speakers but thats a bit out of my league right now for say twenty years or so.

neomagus00

db is cheaper than mmc with good reason - the mmc simply sound better

whether the sq difference is worth the $$ difference is a personal choice

1996blackmax

What is your budget for the speakers, meaning what is the most you are willing to spend?
