Car Audio Questions ???

[pinknerve]

Ok, well, my question is about my subwoofer, which I should be getting very shortly. It is a Polk/MOMO 15"(MM2154) sub that can take up to 800 watts peak power max!!!! Now, I also have 4 polk speakers along with it and I was wondering whether I should get an amplifier just good enough for the subwoofer on its own or whether I should get an amplifier with ability to give some more power to my 4 speakers and the sub??? Now, if I get an amp just for the sub, wouldn't that allow my 4 speakers to give out less bass since the sub would produce the bass allowing the speakers to give better sound quality????????

2 front speakers each can give 135 watts peak
2 rear speakers each can give 180 watts peak
Subwoofer can give 800 watts max peak

With all this info can somebody help me out and give me some advice?? Also if it is a good idea to have an amp that can give power to all 4 speakers and my sub, how many watts should it have to not blow out any speakers or sub??????? Thanks,Pat

In my experience going with the dual amp setup is a much better setup than using one single amp for all five speakers (if there is only one sub of course). I am currently using one four channel amp for all my cabin speakers and one bridgeable two channel amp for the two subs (10" polks I might add). What this does is allow the 4 channel amp dedicate more power to the cabin speakers and not have to sacrifice clarity for a bass note, which draws alot of current. 15" subs is a bit much for my taste but thats what its all about, ORIGINALITY,...right :)
As long as you set your xover freqs right you should expect great clarity and punch from your cabin speakers and your sub should fill very nicely the low end and kick.

stop reading and judging off of max rating. you're wasting your time.

Have you tried the car audio section of the forum??

[elessar117]

I don't know what you are reffering to since there are no ratings posted at all. this was just a simple question and a matter of opinion. I agree that the question should have been asked on the Car Audio forum but no polkie should be left in the dark about audio, for is it not this the reason that we seek our fellow polkies out for answers.

Yes, but chances are many more people will be taking a crack at it on the Car Audio side.
When Toxis said ratings, he meant max power ratings, which mean almost nothing, stick to the RMS values, that's what really matters.
