You want to talk about power. these guys are powerful I got 2 6 1/2 in the back and two 6 1/2 in the front doors and I am about to go deaf, I really can't turn the xbass on my boss audio 7970 all the way up because I'm afraid, I might blow my windows out, great price too, just awesome!
These speakers are worthless the wattage says 400 but its more like 90 watts max my 6.5 jensens i just put in sound way better i recommend alpine or JL audio for 6x9's and for 6.5's
I have these Boss Audio 6x9 400W 3Way Speakers, Boss Audio 6.5" 250W 2Way Speakers, 2 Boss Audio Tw18 tweeters, 2 Boss Audio P12s rated at 1000RMS a piece, 1 Boss Audio 4000W Outlast Amp,A Boss Audio 4Fared Capacitor, And a Boss Audio 7" Touchscreen Flip out Deck to top Bring it all together. I have all this in my Eclipse Gst. No ones Sh*t hits harder than mine. Keep in mind this is a professionally installed system with the best tunning, But its only about a $900 4000W System. If i would have bought these at retail prices it would be a $1600 system. BOSS AUDIO 4LIFE
