Those kicker 2 ways sound good for the money. the kicker 77kick10 mopar kicker speakers are only like $70 on ebay. You may need a small piece of dynomat in the inside of the soundbar on each side because the added bass can make the soundbar humm. My last jeep had 2 way crossfire audios up there and they made the bar buzz and hum until I added a small piece of dynomat on the inside behind each woofer. By small I mean like 2"x2"
