excellent value for the money

I love this amp. It has guts, power and it can push more than stated. I had it pushing 10 speakers: 2-6x9, 2-5x7, 6-Pyle Plus 1" dome tweeters. I have not had any problem with this amp at all. It does not even get hot. I highly recommend this product. The SPL-GRLA840/4 sounds great.

It's ok

It's great till it overheats. I sent mine back. Doesn't push the power it claims!
