Nice Amplifier but has cooling problem

One week after installation, the cooling fan started failing. It made a high pitched screeching noise and then stopped spinning. Rather than send it in for repairs, I replaced the fan myself. It has performed very well since the repair. I have no other complaints about the amplifier. It has a very clean and powerful sound and seems to be a great match for my Boston Acoustics SR95 6x9's.

good amp

Very small, packs alot of power. It is a GT. Just like the big ones. Does not accept remote. It is big enough for a sub.

Awesome amp

Was skeptical at first but decided to pick up this amp anyway to run a set of pioneer ts-d1720c components and was not dissapointed. Mounted it under the drivers seat and it still manages to stay cool on 40c + summer days.

Pros: Perfect for a set of component speakers. Sounds loud and clear, people are surprised when they find out it's only a $100 amp. Fan is very quiet when it is on (I say that because half the time the amp runs cool enough to not need it on)

Cons: Not a fan of the top mounted controls, makes it a bit more difficult to tune when in tight spaces. Plastic mounting feet are flimsy but do the job. I also found the onboard mini anl fuse a bit odd, but it does its job.

For the money...

I'm a firm believer in you get what you pay for when it comes to car audio. This little gem is no different. Don't expect it to produce like a slash series JL and you won't be disappointed. For the money, it gets down. Only con, as with any amp you overwork, is that it does get quite warm.
