Bronze Member Username: L25Post Number: 16 Registered: Sep-04 | This is my first car stereo. Sounds great but I want it to kick harder, it shuts off at high volume with alot of bass. My amp gains are set very low (2). Sub amp base boost set to zero, controled by remote bass level. What is the weak link? Can anyone give suggestions to improve this? Thanks, Jeff Here are my specs: 1999 tacoma shortbed pickup HU Pioneer Premier DEH-P860MP Kicker KX550.3 @ 13.8V, 2U Mono, 1.5% THD 400 x 1 400 x 1 Dynamic Power In Watts, All Channels Driven @ 14.4V, 4U Stereo 70 x 2 70 x 4 @ 14.4V, 2U Stereo 80 x 2 80 x 4 @ 14.4V, 4U Mono 165 x 2 SUB Power In Watts, All Channels Driven @ 14.4V, 2U Mono 420 x 1 420 x 1 MTX 10" Thunderform 4500 non amplified Power Handling: 225 Watts RMS* Sensitivity: 87dB* Enclosure Volume: 1 cubic foot Impedance: 4 Ohm* CDT Audio CL-51 5-1/4" component with SatNet 456a Xover and Image enhance tweeters 80 watt RMS |

AudioFreq Unregistered guest | Weak links... for one, the speaker you can gain 6-10 db overall very easily buy purchasing a better and more efficient sub. If you want it to kick harder... there ya go. Get a larger alternator. Add a stiffening capacitor 1 farad and a battery isolater with secondary battery. This should prevent a lot of the shut downs if the gain is correct. http://www.allexperts.com/displayexpert.asp?Expert=63518 |

A 1 farad cap is always a good idea. .5 is a waste of money since a 1 farad only like 30$ more and you would get twice the product. Use 8 g wiring or 4 g if you want to run bigger amp. Good high end rca cables. High end speaker cable. (I use monster cable). Careful with the deck, Ive had bad experiences with multiple pioneers. Other than that its chill. |

Bronze Member Username: L25Post Number: 18 Registered: Sep-04 | I am using KnuKonceptz 4Ga battery and ground cables, 12 Ga speaKer and RCA Kable, overkill for my setup. So either my sub is not up to the task or my alternator, or both, but what are my options in this teeny cab? I might have room for another custom sub enclosure behind the passenger seat, but it would be even smaller than my thunderform. Being a complete idiot, can anyone suggest an appropriate alternator? (reread my first post for details.) Thanks, Jeff |
