Good Amp
My opinion of this amp is good. I had problems with engine/alternator feedback and then began going through troubleshooting steps. My results from troubleshooting indicated that I had too small of power and ground conductors and I needed to re-route and sheild the input and speaker wiring away from the power source. In doing this I increased my power + and - DC wiring to 2/0 but the terminal lugs at the amp in my opinion were way too small and would not accomidate a larger wire guage without shaving and modifying the connectors and even after that the phillips/slotted screw connector was not rigid or strong enough to make an adequate tight connection. I think the amp should come with a remote sub control not just a connection as standard equipment. The terminal lugs should be large enough to support wiring that most installers would use for a 3700 Watt Amp and that it should be of hardened and/or high strenghth brass or gold plated material. I think the installation instructions are too simplistic and the consumer could greatly benefit from a much more in depth installation guide denoting wire sizing and installation help. A complete troubleshooting guide regarding noise and interference due to installstion mistakes and inherent car noise. The online help that I used came from other manufacturers like Crutchfield and Kicker but Boss had very little supportive invormation in helping me diagnose my problems. Please understand that some of us are not professional installers and require a much more step by step descriptive installation manual in order to avoid having to redo the installation. I being on of them it took me three times having to disassemble the entire interior of my car before I got it right. That being said I made my own homemade 100%sheilded RCA input cables and twisted pair speaker output cables, increased my power wiring sizes, rerouted the wiring and reassembled the car. It sounds fantastic! I am very happy with the amp at this point and love the standard crossover and switching capability of the amp. I am a happy customer but it took blook, sweat, agrivation, perserverance, and patience to achieve the expected results.
