Customer Testimonial

Sonic was very patient with all of my questions about installing and purchasing products. I took more time then most people would. Not once did Mr Brendan H. give me any negative feedback. I would highly recommend both Mr H and Sonic Electronix.

Very good small unit, installed on a 21ft bay boat with small console, great setup with Ipod integration and enough power to drive four speakers well. I would recommend this unit.

Well it would be good for a basic system in a fishing boat but it does not have enough power for the sony 10's but it does power the 6.5s great and the built in cross overs work well but not for the big speakers even brigded it still is bairly enough for the 10s to work ok. Would buy but its not as much power as it says! I bought 2 amps 2 10" subs and 8 6.5 all sony seem to be great just the amps. Power is over rated but works great for everything else!!
