I have a fosgate amp that does 50x4 at 4 ohms.

that's plenty to power up your 4 speakers.

it's in very good condition. Let me know if u wanna buy it.

75 bucks! shipped

 

Personally I would upgrade the speakers in the car, and amp them so your system will sound more in harmony with your subs. You have 2 loud 10" subs and the crappy bose speakers to partner up with them....... I would defenitaly upgrade the speakers to get some better sound quality, and if you are doing this in stages, be sure to buy speakers that are meant to be amped, because if you are going to do it right, you might as well do it right the first time (I am still learning this the hardway as I am replacing equipment that I bought just last year.... ).

 

The stock speakers!

I agree with Mckenzie 93 you should replace the speakers in your car. I'm sure your subs can be pushed more getting more bass but 200 watts of bass is till great for you low frequencies. Replacing the stock speakers may in fact increase the quality of the subs as well to you as a listener as the muddy bass sound of the bass will be gone. Your subs may be powered enough for you but the weak bass sounds out of the"paper" woofers may be destroying the quality of your overall bass/You can replace your speakers directly but you must remember that the Bose speaker are 2 ohm speakers and are powered by a 4 channel 2 ohm amp . If you have an aftermarket deck you can rewire which is a days project but well worth it. I would definately change the speakers but let me know what you think or if you have any questions?? I rewired my whole car with rg8mini coax cable as it is a shielded cable. 1
