[QUOTE="shizzzon, post: 8474771, member: 590338"] The reason why you are reading wiring to higher ohm load (4ohm) is typically because of buying the cheapest amplifier for the highest actual output power. These amps listed already are really pretty cheap in terms of quality. I can say that clearly by some of them stating what their Damping factor is which is pathetic. The lower you wire an amplifier, the lower it's damping factor which translates into exactly what you do not want. You want a high damping factor amplifier. Zapco, like you mentioned before, has VERY high damping factor. One of the amplifiers listed here has a damping factor of 200. This is the typical low quality control for cheap priced amplifiers. I know of an amplifier line coming literally any day now which is built from buildhouse that only does high quality manufacturing of electronics and low powered speakers. They do not care about SPL, only sound quality. This Class D amp is- Actual tested output 375w 4ohm 642.2w 2ohm Damping Factor- 656 Compare and see for yourself- Phoenix Gold RX 500.1- Efficiency- 50% Damping Factor- Greater than 200 PPI Phantom 1000.1- Efficiency- unlisted Damping Factor- Greater than 91 Class D amp i'm talking about- [B]Efficiency- 90% 4ohm | 87.8% Average to 2ohm[/B] [B]Damping Factor- Greater than 650[/B] Zapco Z1KD (300w 4ohm) Efficiency- 86% 4ohm Damping Factor- Greater than 350 Interesting isn't it... PM me for more details.. They have over 15years experience and have just recently starting branding their own work. They used to OEM for years. [/QUOTE]
