Kicker Solo-Baric L5 Car Subwoofer - Page 7 Questions & Answers
I have 2 kicker lmpulse 1x402 amps. How do you hook both in line to power 2 10" subs, 4 ohms each
It isn't wise to connect the business end of amplifiers together so if you want or need to use them together you do it at the input end.
It is better to use an active rather than a passive method, simply connecting the inputs together in parallel would work but is not recommended and the results are unpredictable. A passive splitter would be better and produce more control and predictability.
It depends what results you are looking for. Clearly it is better if each amp drives only one speaker, especially if they aren't an electrically matched pair. If the amps normally require an 8 ohm speaker it should still be acceptable to use 4 ohm loads as long as the peak input at the front end doesn't exceed half the rated maximum.
You could use one amp on each channel for stereo via a suitable preamp or you could use an active phase splitter and use the two amps as a single push-pull amplifier with two outputs or with a front end filter you could make one amp work on the bass to midrange frequencies and one sub-bass to bass frequencies.
Some of the stuff is probably commercially available but some would need to be constructed so what you need is a friendly tv engineer or an electronics enthusiast...
