CLARION SW2513B BASS BOX TALK AUDIO TEST BENCH
Adam Rayner hooks up a CD deck to a decent amp – from Clarion and runs it bridged to test the SW2513B passive ten incher ported subwoofer enclosure. This is just £81 on www.clarion-shop.co.uk but only £73 less a penny on Car Audio Security’s website, which is utterly trustworthy.
