some people have good luck with MA Audio. personally I dislike the company. They used to go by "Mobile Authority" if that sounds any more familiar. They probably are marginally better than Sony and Pyramid, but I wouldn't rank them at even the reliability or performance of Audiobahn. While I'm not an audiobahn fan, that's mainly for company practice reasons, and such more than as in MA Audio's case, where it's for reliability.
they are fairly cheap though. if ya want to give em a try its up to you.
Glass, that's a good explaination on MA Audio and Audiobahn. Lot of people are curious to know why a person dislikes one brand/product over another. I think if everyone gave opinions/facts like that, there would be no time wasting arguments on here.
so if i used the ma audio hk-802sx amp (4400w) and the kicker solo x 18 (5000w) sub would that work?
From my experience they have very good SQ. Way better than sony and pioneer. I heard their highend stuff is very very good. And that is a high end item you want there. Just make sure you have an HO alternator for that beast.
If you're going to use the max rating, then make sure you use it for both amp and sub. That way you're comparing apples to apples. However, Pyramid and Sony and few others, like to throw a monkey wrench into the mix. Instead of using the standard formula to calculate peak power, they make up their own rate. This is why, people get fooled. 1000W from one company may only actually be 500W. The ratio between rms and peak should be 2 - 2.5 times. I've seen as high as 5x, so be careful.
actually don't even use max to max comparisons if the products are made by different companies, because "max" ratings are essentially numbers pulled out of the air, and have no relative value across the board compared to RMS values. max for one product may be 3 times the RMS value, and max for another item could be 5 times the RMS value, or only 2 times the RMS. just stick to RMS for everything and keep life simple.
if you find an amp that puts out 4400 watts of power RMS, you better have about 3 alternators in that car to handle that current draw, because it's going to be ungodly.
