Summary: Bought on recommendation from Crutchfield advisor to match up with a single Kenwood shallow mount 150w 8" sub. It's been only 3 weeks but so far I am pleased with the matchup. This a simple amp, no xover settings (built in 80hz lp) just power gain and a bass boost option (great for some stuff, over powering for other) I may opt to get the remote bass control (not offered at Crutchfield?) for a little more control (I listen to a wide variety of music).
Pros: Simple setup. Turn on options. Extra terminals for paralell setups.
Summary: Beautiful sounding amp. Especially for the size and the price. For a struggling college student, this was definitely a good purchase and should last me well until I'm able to afford a more powerful system.
Pros: Low price. High Quality.
Cons: No filter adjustments and the gain control knob is sold separately. And honestly I wouldn't mind getting a decal with the amp. Just saying.
Summary: It's pretty cheap which is good and pushes my 12'' kicker comp , but if you wanna upgrade to a heavier subwoofer then you would need more power. I like the bass boost knob and the low input setting, but the gain control needs to be adjusted with a screwdriver which is fine, but I like to adjust my bass while I am driving. This is an easy fix if you have the gain control remote, but that remote is sold sepratley.
Summary: This amp performs well for the money. The reason I gave it only 2 stars is that the instructions and manual suck. It is a mono Subwoofer amp and there is NO I REPEAT NO instructions on hooking it up to the sub. There are 2 channels on this amp like any other amp. I have no idea if I am losing power due to incomplete instructions. Let me be clear, I have been hooking up car stereos for over ten years, I know what I'm doing.
Summary: Not a bad starter amp, very little controls besides gain and a bass boost. Its a simple mono amplifier with 250 watts of pushing power. I have it hooked up to a single sony explod 12" which seems to be a little bit too much for this little amp to handle, but it still does push it decently. Its probably best with a smaller 8"-10" bass tube or sub.
Pros: Build quality, price, simplicity
Cons: Power output, gets very hot if you don't give it a small gap of air to run under it, tempermental with the auto turn on, only worked with REM wire.
Summary: Installed this in my 91 Miata with 8 inch Kicker subwoofer and Clarion head unit. Much better sound then I anticipated. This was a parcel shelf installation with the amp mounted in the trunk. I previously replaced the factory speakers with little improvement.
