Had these almost a month, and have excellent bass from my Alpine head unit (pushing 17watts per channel). These also fit perfectly in an E30 (BMW). The highs are superb, and I have to turn down the treble.

The stock speaker wires plug perfectly into the speakers, without any need for cutting or crimping new ends. Installed and tested inside 20 minutes for the rear deck lid, and about 10 minutes for the front kick panels.

Also, these speakers fit with the stock (OEM, BMW) speaker grills, so it will look like factory speakers to the world (who may want to steal them), but they are much better. BTW, the factory BMW speakers are really good, and it's hard to find good replacements for them).
