Hello

Just bought this amp for a good price, and wondering if it's any good? Condition of it is really good, and inside is clean too.

From doing little research i found out that it's rated:

Output Power at 20Hz 20kHz:

4 x 35W @ 4 or 2 ohms

2 x 70W @ 4 or 8 ohms bridged

THD: <0.1% (20Hz 20kHz, full power, 2, 4 or 8 ohms)

S/N Ratio: >100dB

damping Factor: >200

Max. Current Draw: 45A

Question is, how do i hook speaker up to it? Do i need to buy crossover too?

You have a real nice sq amp for low power, its 35x4 at 4ohm and 45x4 at 2ohm it was one of the best amps that thay made nice sq but dont make alot of power sounds nice with some good comps, you can send it to me and i will take good care of it for you... :yahoo:

lol I need 2 channel amp, so i'm guessing it's 90wrms @ 4ohm? What about gains and other stuff, how do i tune that? btw, payed $8 for it.

See the lil black gain pots on the board there should be holes in the heatsink for them that's the gain left and right for each channel

On button there are 2 switches " mono" and "Stereo" for A and B channels .

What's the active xover? never ran it before, but heard of it.
