no, kenwood isnt a good brand, their speakers have terrible sound quality and their subs arent that great, their amps are decent but go with it if thats all your budget can afford go for it
but look into mtx, kicker, jl, alpine, even peioner, for speakers tho not subs, polks are also terriffic for speakers they sound great.
mtx makes thunderforms which come powered with an amp and a sub that fit specifically under your rear seats or behind them or whichever you are looking for. search mtx thunderforms on google and you can find eventually ones for that vehicle
