Car Audio: Would it sound much better if I replaced the factory Audi Head unit with a aftermarket deck ?

I added 2 12" Kickers with an Alpine MRP-1000 and the bass isn't hitting like it should. There's also a hissing noise while the amp is powered, with it clicking and popping when its turned on.

Would changing the HU make the bass hit harder and eliminate the hissing ?Car Audio: Would it sound much better if I replaced the factory Audi Head unit with a aftermarket deck ?The other answer is correct in that the clicking and hissing isn't just because you have a factory head unit. There's something wrong with your installation (ground, LOC, etc). If it wasn't professionally installed it would be a good idea to have someone take a look at it for you.



With that said, of course you're going to have a better system with an aftermarket head unit. For SQ there are some factory head units when adding certain aftermarket solutions on the market that can sound good, but if you're going to spend all that money it just makes more sense to replace the radio (if it's possible). For starters as long as you're not trying to by something entry level you're going to end up with more features. With a decent radio you can get Pandora support through the iPhone app (if you're an iPhone user), HD radio, Bluetooth, and even Nav in a double din. For SQ if you choose an aftermarket radio that has a parametric EQ, crossovers, time alignment, and 4V preouts those are all features you never see in a factory radio. Also you can find yourself something with a 24 bit d/a convertor too. It all depends on your budget but replacing the head unit can have a big impact on the overall SQ of your system.Car Audio: Would it sound much better if I replaced the factory Audi Head unit with a aftermarket deck ?No it would not. A lot of people do not realize that MOST factory head units are better quality in sound quality than an after market one. The noise you are hearing is most likely ground loop noise. You prob do not have a good ground on your amp. Or it could link back to your LOC (line output converter), you prob used one because it is a factory head and will not have RCA outputs. If you wired this up wrong it can be your problem. Also do not run your power wire and RCS's on the same side of the car. You did not give me much info so this is the best help i can really give with the info provided. Hope I helped.
