So I just installed two sets of Alpine SPS 517 speakers in my car along with a Kenwood KDCX302 headunit. Now, id like to get a subwoofer and amplifier professionally installed. I need some help though on choosing some solid parts. I know the best option would be to get a 4 channel amp and a mono block however that's a little too pricey for me right now. So now I'm debating between getting a 5 channel amp to power my speakers and my subwoofer, or returning my kenwood head unit and getting a Sony MEX-XB100BT to power my speakers and a mono block amp.
I've had sundown audio in the past for a subwoofer, and I definitely want to get an 8" sundown audio subwoofer. If someone can help me choose the correct one, an enclosure, and an amp that would be really appreciated. In the past I had a lot of luck with SoundQubed amps, I really like the bass control with clipping light, but I'm open to whatever. I really don't want to spend more than $200 on the amp though. Thanks!
