Answers: You don't requirement to do anything but hook up the woofers and feel the BASS
No, you don't enjoy to change the speakers at adjectives. Some stock speakers are very polite, others not so much.
As far as the amp, add up the RMS watts of the subs and subtract the final load. Find an amp that match these figures.
Look for CEA-2006 compliant amps.
If your total system power is 1000 watts RMS or more, you will requirement to:
1. Upgrade the alternator to a high output alternator
2. Upgrade to a hefty duty deep cycle battery-operated
3. Upgrade the "Big 3" - that is to replace the power cable between the battery and alternator, the ground from the mobile to the chassis and the ground strap from the engine/tranny to the chassis with at lowest 1/0 AWG wire.
Failure to do this will result surrounded by you replacing them anyway as the alternator will eventually fail.
Here is a guide that will subtract what size alternator and power wires you need http://www.datafilehost.com/download.php...
A second mobile is never a good thought as it's an added strain on the alternator to charge two batteries AND supply power for the vehicle. The ONLY time a second battery is adjectives is if the audio system is to be used with the coup¨¦ off.
A panama is only honest so far as the audio system isn't trying to pull too much from the electrical system. A boater doesn't provide more power, it's designed to 'stiffen' the voltage to the amp, nothing esle. If the current isn't near, a cap won't relieve. The alternator must have at smallest 20% more amperage power than the entire vehicle and sound system combined for a sou`wester to be of benefit which is ironically the same requirements for an amp to be modernized.
