Installed this 6x9 comp. set in a 08 Nissan Frontier Front Door (6x9) and dash (tweeter). 150 watts rms going to each side. This component set has some serious volume capability without distorting, outstanding tweeters, 6x9's are clear, even at very high volume, but do not have a strong mid-bass punch. Optimisticly, maybe they will break in and improve. As it stands, I will be installing some kicker 6.5 subs (yes they make them that small) in the back doors and some 8" woofers in the back in order to fill in that mid-bass punch I am looking for. Crossover boxes are somewhat large, but will fit into some vehicles kick panels. I recommend this component set, but be prepared to add something else too for mid-bass.
