Customer Reviews
I am having it installed right now haven't received my car back yet but I will let you know how everything go thank you for being concerned
CTSounds are making remarkable, affordable products . They sound good , look good . I wouldn’t hesitate to buy from them again
I recently swapped out my trusty old school Alpine V12 for this 80.4 to have a matching pair of amps, and I was immediately floored by the improvement in sound quality. This little guy is awesome and my highs are way louder and twice as clear.
I thought it sounded good before, but it's night and day better now.
As always, super happy with the purchase.
If you're looking for a screamer for little cash, look no further.
My truck is insane! Thanks guys!
Great Amp Power My Door Speakers And Crystal Clear Sound!
