Description

RETRO

Early 90s alpine v12 series in Immaculate Condition old school.

Built in crossovers, phase, gain, gold terminals etc.... Usual Alpine Quality

These amps are very powerful with great bass reach and weight married to fine control....Perfect for driving Subs....You will not be wanting for more power!!!

Full range driving ability is also to a very high standard but treble can become a little harsh at very (& I mean VERY) high volume levels - This can be controlled though with careful speaker selection and placement!
