What are the specs on the stock 79-93 amp?

After swapping my stock nugget amp out for a kenwood, the sound sounds staticy then fades in and out for a few minutes (usually after I go over a bump or turn) then goes off till you turn the car off for a few minutes. I triple checked the wiring and it's clean. No crossed over wires or grounded cables or anything and the remote is clean and the amp has the red triangle lit up (meaning it has signal and is on) and it's triple fused so there really isnt anything grounded out. I though she was overheating at first, but after fanning that thing till it's cold, it still does the same thing. I thought I was sucking the juice from the battery but swapping wires to the alternator made no difference and the ammeter reads in the nominal range.

So I got tired of it and put the stock amp back in using the original harnesses and wiring and viola! No more problems. The sound is just as loud as with the kenwood but there's practically no bass. So I got to thinking...... can that little nugget amp power a 10 inch single JBL powerwedge subwoofer? Can the stock amp be bridged (left + and right - )? I would be beside myself with happiness to not have to have 2 amps. I have a filter for the woofer to take out the high signals. What I did before is I realized that there is only 2 channels in a stereo signal , L and R, so the back speakers are working on the same signal as the fronts. So I just hooked all 6 speakers to the front channel and used the rear channel for the woofer. Could the little stock amp handle this?
