Don't let the compact size fool you; Dayton Audio's DTA-1 amplifier has the heart of a serious performer.

The Dayton DTA-1 T-amp can run off of 8 AA batteries for total portability, or the included switching power supply (with quick-release US and European style plugs). A rear mounted 3.5 mm stereo (1/8") audio input. Includes a 6 in. 3.5 mm coiled male-to-male cable for making connections to iPods, MP3 players, PCs,and portable CD or DVD players. Spring-loaded push terminals are designed for quick speaker wire termination. Intelligent short-circuit and over-temperature protection ensure amplifier longevity.

Its ,not designed for big speakers,but if you have some small speakers like mine this is the amp for you,My speakers are (2) 3 1/2 inch cambridge soundworks suround sound speakers 25watts a piece,I recomend you use some fairly new speakers that are high efficent,89db or higher to get that deep rich sound.I was very impressed with the amp,I've tried several different ipod setups on my bike like the I-home,and the handlebar mount I-ride and they both would not go loud enough.Bought this amp now problem solved.I've been out on a 3hour ride with the amp turn all the way up running on 8AA duracell batteries and it never ran out of power.If your thinking about making a setup for your bike I highly recomend this amp.Thanks for the reply..Randy
