What fuse do i use for my Jensen 2 Channel Bridgeable Amplifier with 300 Watts Peak? thank you.

Watts = Voltage x Current

300 = 12 x Current

Current = 25 amps

Sounds like a 30 amp slo-blo fuse would be about right -- you could start with a 25 amp and see if that holds it.

I want a reliable system.

if you bought that equipment today then your answer is yes your amp will power the subs but if i was you and you want more bass I would go with a two channel amp or even a mono block amp that will be 1 ohm stable and if you decide to do that you might want to get subs that are dual 4 ohm voice coils and run them in series that will get you 1 ohm of resistance

I need a wiring diagram for the jensen lxa400. Pushing 2 kenwood 6x9 (200 watt rms each) and 2 dual voice coil 12's (300 watt rms each) in a truck box. Everything is 4 ohm. Thanks, Curtis

you shouldn't need a diagram all you need is these items here.

purchase a 4gauge wiring kit

run a a power line from battery to amp with a in line fuse 6in from battery.

run a ground from car frame to amp. ( scratch paint and screw it down with an eyelet for good contact)

run a remote from radio to amp.(blue wire)

run rca's from the radio to the amp ( sub input on back of radio)

finally connect your speakers.

How many watts RMS are?

Hello melesk82,

The Jensen XA4150 is a 4-channel amp that outputs 75 watts times 4 channels into a 4 ohm impedance.

Hope this helps.

I am looking to buy a 1200 watt jensen 2 channel amp. what model is this? is there a jensen 1200, i have not seem it.

I would recommend you purchase a brand name 600watt RMS amp instead of a Jensen 1200 watt peak amp. Trust me you will notice the difference. Try a kicker, hifonics, MTX, audiobahn Autotech... Its not the watts its the quality of the watts..

4 chanel amp I dont know how to conected,to radioand one subwoofer

Hello canelo63,

Your question appears under the product listing for the Dual XPA4100 but the in the text you say the amp is actually a Jensen, so it's not possible to provide specific connection information.

But most bridgeable amps can be connected to a single subwoofer and the other two channels used to drive a set of regular speakers. I'd connect the front speakers to channels 1 and 2 and wire the subwoofer to the bridge connections of channels 3 and 4. On the XPA4100, the bridge terminals are the first (negative) terminal on channel 4 and the last (positive) terminal on channel 3.

Hope this helps.

You can't bridge 4 channels into one channel. You can bridge the amp to two channels and drive one dual voice coil speaker.


The owner's manual is available from Jensen.
