A Crazy Versatile Amp with surprising Power

The following review is for R-A90S, which is a part of the bundle you are viewing.

Ill start with explaining why I went with this Amp. I have a 1998 Volvo S70 T5 with every option and that includes the Dolby Surround System. That system was designed as 8 Ohm. So I made the decision that I would be completely rewiring the car and removing the factory Amp. The car has a Center Speaker, 2 6.5's with dash tweeters, 2 rear door speakers that are also 6.5's and 2 8" speakers on the deck. The car is loaded with speaker locations and that left me with the need to find an Amp that can power all of this. Enter the R-A90S, With the staggered power on channels 5&6 it was the perfect opportunity to install Alpine 6x9's on the deck to replace the OEM 8" speakers. The only exception is I am running the center channel off the deck itself. Regardless this amp does a great job of giving adequate power to all the speakers. Also this Amp is putting out a health amount of power above what was advertised. Even the included Birth sheet shows their test results on the amp you receive. My amp was putting out almost 15% more power than the guaranteed values.

Bottom line is that if you are looking for an amp to power a non standard setup this Amp allows you to get creative with your install. Its fantastic! 10/10
