In Phase XT-8

Just because it’s small don’t discount it. The NEW In Phase XT range is the second generation of the XT series subwoofers. With some huge improvements to the already fantastic XT series these 2nd gen XT subs really need to be heard and handled to appreciate the true quality within.

The heavy-duty, heavy gauge stamped basket with a black powder coated finish shows it means buisness, and with the kevlar fibre enchanced nonpress paper cone and hi-roll foam surround it can handle some very impressive power ratings. The 1000 watt peak and 300 watt RMS rating has been achieved by the 2” high-temp, four layer aluminium voice coil, and one piece two Layer black poly-cotton spider with substantial double stacked 90oz magnets. All this power is kept cool by the black finish t-yoke with VC direct cooling vents.

Passengers will be blown away and left questioning whether you’ve equipped the boot with a 10 or 12-inch woofer once they’ve heard this combination slam, subtlety and immediacy of bass response.

For tight, punchy, melodic bass there’s no need to listen elsewhere. If you actually want musicality rather than outright soul destroying, window rattling, this 8-inch could be the perfect woofer for the job.

In Phase Car Audio XT-8
simon warne on 23/11/2019 5 star rating

put this in a ported box sounds great nice and crisp hits nearly all the lows for a small sub it keeps up with some big boys

charles on 04/10/2014 5 star rating

I brought two of these along with a custom slot ported box for my polo R 2013. The bass was unreal. I could not believe how low two 8" woofers would go. All my mates think i have two 12" subs. I must say the lads at Leicester made me a excellent box and gave me a cracking deal. 150% recommended!

    Hi - the inphase XT8 has 2 terminals, does this mean my spare 2 channels will both be used? I have an inphase 4 channel amp with older looking screw type terminals

    Car: Citroen C1 - 2005>

    How much amperage is it pulling??


    there is no way to tell that without wiring it in a car with an amp and testing it, as every amp would be different and depending how the subwoofer if wired will also affect the amperage draw
