Pioneer GM-D1004 400W 4 Channel Compact Car Amplifier

Small amp. Big response

If you like driving with the windows down on the motorway but your stock head unit just runs out of steam when you turn it up over the road noise then this will be perfect.
Small enough to fit behind the dash of my Mazda 6.
Loud enough to power my Infinity 3 way 6x9" speakers with loads of headroom to spare at motorway speeds.
Easy to fit. Fantastic valueRead full review

Fantastic little amp!

I highly recommend this amplifier. I have had big installs over the past 25 years, but sadly can't have a big install in my Mercedes Coupe.
This amplifier really has brought the speakers to life!r>It's running 6.5 MB Quart speakers with ease. Very impressed with the sound quality and power for the size. Read full review

A very good compact amplifier.

I put an amplifier in the back of the 2DIN stereo. The sound is noticeably better.

Excellent sound but slight install issues

I bought an adapter lead to enable it to fit into a golf mk7 and it worked ...until I turned up the volume!

The amp draws more power than the radio loom could handle so had to wire to fuse box - which is better but not perfect... need to spend time wiring direct to the battery.

Tiny amp which gives a load more power to the standard head unit - would recommend 100% but make sure you know what your doing if the main radio harness does not have enough capacity for the amp to run on aswell!Read full review
