haha. No budget but I have always used kicker when it comes to subs and amps. I actually never heard much about cadence but a free amp is a free amp. However if there are better I am all ears!
I have a 12 solo baric running on a 750 watt amp. I tried to just let that be enough but the factory door speakers arent enough. I have kicker door speakers laying around and was going to throw them in and hook them up to this cadence amp so I am not all bass. The speakers are 5 1/4 and 6 1/2.
Well, if you already have the cadence amp hook it up and see how it sounds lol. I can't really tell you much since I don't know what model speakers they are, what model cadence amp it is, etc. If you don't like the cadence amp, some of the popular ones out right now are: Audioque AQ4x90, MB Quart DSC4125, and Sundown SAX-100.4D. These are just off the top of my head though, there's a lot more that are currently getting great reviews. The DSC4125 can be had for only $130, though, so it's got one of the best priceerformance ratios out right now...
Thanks for the help!!! I was planning to just hook up the speakers in the rear deck first because they are easy to get at. Are you familiar with BMW installation?
