My first system seemed fine for the first couple weeks until I heard a friends car that was done by Systems Unlimited. He not only spent a couple grand less but got a much better install and overall much better sound using less equiptment. I ended up having them sound deaden the front doors and the trunk as well as build a fiberglass subwoofer enclosure to give me back my trunk. This made a huge improvement on the sound as well as making my car much quieter. It pays to do it right the first time. I could have saved lots if I knew about this shop. If quality is what you are looking for instead of the slam bam then check them out.
