I've been searching for a budget car amp & this seems a good deal as it's over £100 everywhere else.

A question for all you ICE buffs: when an amp like this is described as a '4 channel amp', does each channel have an independent input? In other words, could you use it for a quadraphonic setup?

Also if I have 50w speakers will this make a difference. Just forward planning here for when I get a motor upgrade.

​I don't know much about them myself, but I've read that you can adjust the power output by turning the gain control down, to avoid overpowering the speakers. You can safely power speakers with the RMS of an amp 1.5 x higher than the RMS of the speakers.
total bs on the ratings - you're not going to get anywhere near those even if you had your hearing aid set to as high as it'll go.

if you have the option, I would invest in a decent 2 channel with some modest fronts over trying to to amp 4 stock speakers.

also note that if you amp your rear speakers you'll lose the audible bell of parking sensors (if its built into your existing electrics, fortunately mine was a seperate buzzer).

I'm not going to vote either way. but bare in mind with car audio, generally you do get what you pay for.

I'd like to know this as well. Could it be used at home, with suitable power adapter, as a 4-speaker surround amp with 8 ohm speakers?

2 Pairs of RCA's, so yes essentially a 4.0 system.
8 Ohm, Not likely, usually 4 ohm or below. *if* it did run, it'd be quite quiet, plus you'd need a 14.4v power supply run it

​if it manages half the power that it says jt has, it'll be enough for me at this price. My speakers are 90w rms.
I decided to buy it. Opted for free delivery which stated 2 to 3 days but it arrived the next day.
