I went down to my car audio shop today... was looking to upgrade my 2 10s to something bigger. Was thinking 2 12's or 2 15's but the owner offered to install 8 10" kenwood subs in my trunk for 900$ canadian (no tax) including a custom ported box. Forget the model names, but they are the kenwood subs with 150 w rms each, and i have an amp big enough to power them all. My question is how loud would this actually be? (all in my trunk in a custom ported box), and is it worth the price? What are my other options to upgrading my subs that are worthwhile. (i have a clarion dpx1001.2 amp.
