What is the loudest car speaker?

Need help! Looking for the loudest & clearest sound from 6.5 car speaker-that does not cost too much???

• I have a rockford fosgate amp. 2 channel 35 watts per channel running some Sony Xplod red car speakers 5.25 components with little tweeters 120 watts over all-on a adapter plate to fit 6.5 hole, but I need it to be much more louder!!! I cannot afford the super high price speakers but a reasonable price. I listen to rock music alot. I have a one 12 sub-woofer for the good low bass. I love the 6x9 car speakers performance, but they don't fit in a 6.5 door sides. Thanks :o)

• Answer:

  ive always used MB Quart components if the customer doesnt want to go on the much more expensive brands like Hertz and RE. they are capable of getting pretty loud and still give a good sound quality without distorting too much.
