Ok, I need to make a decision if I should get the 8" BSW sub system @ $650: X5 Subwoofer / Sub System for BMW X5 | BSW

or 10" JL Audio stealthbox @ $550 without amp:
JL Audio Stealthbox® Custom-fit fiberglass enclosure with 10" W1v2 subwoofer Fits 2000-2006 BMW X5 at Crutchfield.com

If anyone has either please let me know how you like it. Also, I have a Hualingan head unit.

Another question I have is the JL does not come with amp, so what amp should I get that goes with the sub (up to $150 max)?

OR I should buy and empty custom enclosure from someone in the forum and buy separate sub and amp (have no idea what to get though for separate sub and amp)

Please help me decide.


Any feedback would be appreciated.
I have 2001 X5 non dsp (only factory amp and hualingan head unit)

Thanks.
